I thought it was an interesting discussion and I'm not sure why the OP requested a lock.

While many seem to think that you just leave a Glock alone, it seems the best pistol shooters in the world have decided to put together their own custom guns.

There was a good thread on Primary and Secondary but you have to register to see it.

12/23/16 Update:
I'm updating this thread a bit to include the term "fauxland special". The Roland special is a very specific setup: Glock 19 with frame work and slide milling, stock internals, KKM bbl and comp, Trijicon RMR, and an X300U.

What about pistols following this functional theme but not actually being Roland Specials? Unlike a clone AR thread that balks at "inspired-by builds" I'm amending this thread it to include similar glocks that deviate from the specific configuration but fill the overall function: RDS and comp equipped Glocks that aren't competition oriented "open-class" rigs.
G17s, ATOM/ZEV/etc slides, other optics, upgraded triggers and internals, TBRCI comps, non-KKM barrels, non-x300u lights, lonewolf/P80/CCF frames etc... do not a Roland make, but they are functional equivalents that are being termed "faux-lands".

Main thing is that KKM Barrel/Comp combo uses a weird 9/16x32 thread pattern for which there is almost nothing else that will fit it.  If you want to be able to use your barrel with other stuff, you'll need to just get a standard 1/2 x 28 thread pitch barrel and use the Micro Comp.

The KKM and Micro Comp perform fairly similarly in terms of felt recoil reduction and it is worth noting that both will cause sporadic issues with 115 gr if you don't can't the OEM recoil spring.  The only difference I've noted is the amount of flash and gas.  Wholly unscientific, but it seems that the Micro Comp is actually less flashy thanks to gas dispersion features on its top port, resulting in more smoke.  Haven't had a chance to compare both side by side, just my observations from shooting a bunch with seperate builds over the last few weeks

Anyone using a DPP? I'm heading really good things about it, it's just going to be a hassle to put BUIS on.

With a similar setup, plinker 115 gr from PMC and WWB sometimes gives me issues thanks to the KKM comp being too effective.

I avoid the issue by primarily shooting 124 gr and higher.

I am a bit temped to put together an ISMI guide rod, spring, and Gen 4 to 3 conversion plate for when I'm just plinking.  Not an expensive conversion at all.

Putting blue loctite onto the barrel thread itself is over the top and it will definitely, definitely work hahaha, especially if you degreased the thread and comp.  I did it out of curiosity and it was stuck on there:  figured you might not even need the set screws if you did that (ala the Carver Comp, which just uses red loctite).

For me, just degreasing the comp/set screws and only applying loctite to the set screws was enough.  Without loctite, the comp would come loose after half a mag... but never got dangerous since the guide rod prevents rotation

I've got a G17 ATOM slide. Which is really cool for optics evolution, but doesn't allow the optic to sit quite as low.

I'm torn between the RMR and the Delta Point Pro. The RMR makes everything easier mounting wise, but the DPP straight up looks like the better optic.

I got the info I needed of the P&S Facebook:



The OEM ATOM sights are .365

I've got time but I need to decide between the DPP (still waiting to find out Fed/MIL pricing) and new BUIS or just getting the RMR.

I'm also trying to decide between the KKM setup and an S3F/TBRCI setup.

Just waiting for my frame to come back from Olympic Cerakote and more funds to free up.

That's why I'm leaning that way

I'm not convinced that comp will do anything other than weight the front of the gun considering its attached to the slide and chucked with the barrel.

Part of the reason a pistol comp works is that the gas presses on the comp increasing the lock time and slowing the pistol slide down. An open top slide mounted comp that chuckles without the barrel isn't going to do that or redirct gasses.

He probably got it from me since that's my photo I took of one yesterday haha

We ordered a bunch in December, finally got em Friday, sold out immediately.

We've got more standard and nitrided ones on backorder now.  I even gave up the one I was hoping to keep for myself!  This next batch should be in a lot quicker:  a production batch at KKM was lost due to flooding and heavy rains in January, hence the delays.



If you mount it onto a Glock, you need a sealing plate from Trijicon or Battlewerx etc to help with water proofing.  We sell the Battlewerx ones because they are cheaper than Trijicon AND have the dimple which pushes the battery up.  However, the most important mod you need to do is to modify the side battery contact.  The anti-flicker plate, shoe-goo on the battery... those are not as important as modifying your side battery contact.

I posted about it on my Instagram here and i showed mine.  Mine is not done too well... I'd prefer it have more of a curve, but it was the best I could do with my basic tweezers hahaha!  You just have to be careful to not bend past the point of elasticity and break it!  Without the mod and just an anti-flicker plate, mr RMR went to 1000 rounds or so before it had issues.  Without an anti-flicker sealing plate, my pal's $2500 custom tuned G-19 with an RMR started flickering after 12 rounds LOLOLOL!  

The RMR's housing, electronics, and glass... all hella tough, hella hardened.  The achilles heel is the power supply design, designed before slide mounting was a thing.



I also shimmed mine with a bit of cut up gift card... but that's not really needed.  Some folks use foam etc.

A Deltapoint Pro has a MASSIVE side battery contact that is two pronged... at 12 o clock.  More shock = More contact.  The RMR's baby dick of a side contact is at the exact wrong spot at 9 o clock too.



My thoughts on the Delta Point Pro are

DPP Pros

1.  Way larger window/aperture.
2.  Way clearer window/aperture
3.  Smarter power system.
4.  Recent price cut (New MSRP is just $400 now)
5.  Secure, yet easy to access top loading battery
6.  Great warranty from an American company.  If you manage to break it, Leupold will take care of ya!

DPP Cons

1.  Very very tall, so you need a very, very tall front sight.  .385 and .495 are the heights I've encountered, pal at Leupold told me .385, another pal's build is the taller one.  A massive front sight is a real pain in that it snags on a lot of stuff.  That being said, the DPP is very reliable and lets you know when it's batteries are running out.  BUIS are not absolutely critical on it IMHO.
2.  Battery Life:  According to folks who have been using them professionally, they replace em very very frequently (weeks), though some folks are reporting 6 months with nominal daily care use.  Ease of access to the battery compartment is very handy here... but also makes the difficulty of co-witness with irons a bigger issue.

My thoughts on the RMR are as such

Battery powered RMR Pros

1. Strong strong strong.  The housing is famously strong, and newest production models have have hardened electronics to better resist shock.  The Glass is immensely thick, and feels twice as thick as the already thick DPP's glass.
2. Better lower profile mounting/BUIS.  With a bottom loaded battery, you can get the RMR low onto a Glock and co-witness with regular suppressor sights.
3. Custom fitting is an mastered art.  The folks at ATEI and others can custom fit RMRs, so the tough housing is basically perfectly fit onto your pistol, and a part of it
4. Long battery life.  The tinted window and adjustable LED tech gives the RMR a battery life of up to 4 years, though most folks swap the inexpensive battery at 12 months when daily carrying.
5. Proven service:  Doug from ATEi has an early model RMR RM01 and after mods... it's been through 20K rounds easy.  Some folks in the LE world are also up there with their RMRs in terms of round count, post modification
6. Superior Battery Life.  Practical battery life on battery powered RMRs seems to be measured by years.  4 years supposedly
7. Great warranty from an American company.  If you managed to break your RMR Trijicon will take care of ya!

Battery powered RMR Cons

1. Expensive.  Quality costs money... especially the adjustable LED models which are the clear favorite.
2. Smaller aperture.  The smaller aperture is very unforgiving.  Your pistol skills need to be on point... or your BUIS are more important, depends on how you view it.
3. Power supply system needs modification.  Takes 2 minutes start to finish when you have an experienced person like myself do it.  I am considering buying a surgery tool so I can get more of a curve on my side contact bends hahaha

I think the DPP and RMR are both fantastic choices, and the best choices at this time for a weapon mounted MRDS.  Everything else out there is a value/budget buy.  I'd run either a RMR or DPP happily and work with their respective strengths/weaknesses alike.  Some times I'm biased towards one sight, sometimes I'm biased toward the other.  In terms of cost/performance I think the RMR and DPP are on the same marginal utility curve.

Seems to me the only real drawback to the DPP is the sight height and that the optic itself is much more developed.

The RMR is a lot more theoretically durable though.  When it first came out, we did some informal abusive testing of the RMR on AR-15s and concrete, since dude was a volume dealer and had ordered enough to get one for free from his sales rep.

The DPP is no slouch, but it is not as theoretically durable as the RMR.  The RMR is more durable and has way better BUIS options... but is harder to use.  It really boils down to individual user preference.  For competition guns... DPP all the way.  For fighitng guns, you can use either, but the RMR definitely has the edge in terms of durability and better iron sight options.

I've been borrowing a RMR and a DPP equipped slide from a pal, and I like em both.  I strong prefer the lower profile RMR for daily carry, and the much clearer DPP for shooting at the range, at competitions etc.  Won my first match today with a DPP equipped G19



My bro at Leupold hooked me up, got like 5-6 headed my way from Oregon on Monday.

Most distributors are shit out of luck on DPP since the military and Cabelas is buying everything they have in stock for the next X months.  

I'm going to be getting "blem" units, and they'll be priced as such!  My contact is telling me that the blems are extremely slight, as Leupold has very high QC standards.

There's 2 types of durable though. I know you know this, but many people conflate the 2.

There's the external durability of the sight's housing and glass against being beaten,  hit, slammed, etc...

There's also the internal durability of the device and it's circuits, wiring, battery contacts, etc... against the recoil forces produced.

From all appearances it seems the RMR has the first and the DPP has the second.

Yup, absolutely true!  One thing is that the RMR's guts and electronics were soft upgraded a few years ago and are very, very hardened from what I know.  

It's really just the original design problem of the side battery contact that's holding the RMR back.  It's crazy, but 2 minutes with tweezers and the flaw is fixed and the RMR's overall durability surges past the DPP.  By bending that contact ever so slightly that little bit of mass you put at a slight angle makes the RMR impervious to slide shock causing interruption to power supply.

Maybe Trijicon will update the design or retrofit a more shock proof electrical system into the system... but in the mean time, a super, crazy, easy mod makes your RMR crazy durable.

Supposedly, some people don't ever have the issue without modification:  I'm not sure that I buy it.  I am far more convinced that most people just don't shoot their guns.  I kept my recent production model RM06 stock just to see how long it took for me to encounter issues:  less than a case of 9mm on a comped (slower slide velocity) pistol.

This was discussed on the Primary and secondary Facebook recently. I'll see what I can dig up on it later.

i tried mine this weekend and it stovepiped almost every round shooting 115grn Fiocchi, I will try some heavier loads next

Were going to hit that crap product point soon if we haven't already.

Considering comp purchases were rare (until recently) it was a performance part that needed to work. No one would make an aesthetic piece because competitors needed the performance.

Now that everyone wants one regardless if they even work, and more companies are turning them out, there will be a rise in garbage comps. In fact looking at the designs of some we might have hit that point following the TBRCI comp.

At this point, I'd stick to KKM or TBRCI until someone else does real legwork on the late comers.

As a side note, if anyone wants a duty style holster and is concerned about the SLS locking up, check out the Blackhawk Omnivore
Retains the gun on the light, fits any gun with that light, and looks to have clearance for a RDS, will fit a G34 and goes for $55.

I'm not a Blackhawk fan, but this looks to be miles ahead of the Serpa and a good temporary option until the Safarilands come out or you can swallow a custom holster.

Yup, with the gassier/hotter 115 gr loads you're gonna have a lot more issues since the comp is doing it's job too well. I had a lot better luck with PMC 115 gr (1 stoppage a mag or so)

One solution is to get a ISMI guide rod and 15 ft/lb spring which works out of the box with Gen 3, requires a $12 adapter plate for Gen 4.  Another solution is to shoot 124 gr and higher.

That's hot!

I ended up letting mine go since I didn't want to take a bunch of pics of it and not have any on hand for folks to have hahaha.  I'm waiting for my slide from ATEI too!  Just went with mounting, side serrations, and black nitride refinish myself.  Gonna start reselling ATEi services as a dealer now!

Anyone ever cut and thread a G34 bbl for a G17?

Gotcha. My frame and slide are tight and designed around swapping in to tighten the OEM parts. So an after market bbl may be too tight on either the lugs or the hood.

Seems like cutting a Glock bbl might be my only "good" option. Plus then I could get it timed with the comp.

Any suggestions for places to get this done?
