Just started having issues with my kkm comped 17 running +p with factory spring.  Traded out for 13 lb flat spring and guide rod, still seemed to have a few issues but not nearly as many.  Also running +p.  Wonder what else needs to be done.

How gunked up is the gun? For whatever reason, my RS starts to throw the occasional malfunction if I really let it get nasty. However, my RS also likes a little more lube than your standard glock.

It was pretty dirty.  I did give it a thorough cleaning before the last range trip this weekend and before testing with the 13 pound spring setup though so i don't know.

I’m glad I saw this about the comp and using hot ammo. I’m going to go ahead and stock up on some +p hollow points.

I know y’all are saying that the longer slide pistols are prone to weak cycling with a comp. I take it that the 19 has a barrel length better suited for it?

What +p SD ammo are y’all using?

For 9mm, things get difficult bast G19 size. A lot of people have issues with 19 length as well depending on what barrel & comp.

I run Speer Gold Dot 124+P through my KKM barrel/comp.

124gr NATO for range/practice ammo, Hornady Critical Duty 124gr +P for carry. The recoil profile is so similar I can’t tell the difference if I shoot a mag with a random mix of the two (only done for reliability testing, obviously don’t mix different ammo loads for defensive purposes)

Can you elaborate on the issue? Is it failing to return to battery? Is the spent casing stovepiping? Trying to get a sense as to whether the issue is happening on the slide rearward or forward travel.

My 19 Roland is 98% reliable with a 13lb spring but wasn't even in the ballpark with a factory or 15lb spring. You can go lighter than 13 but you start to beat up the frame and at that point the spring doesnt have much energy to send the slide home. It's a delicate balance.

What's everyone's current favorite trigger setup? I've got everything else ready or ordered, but haven't decided on the trigger yet. Never had any aftermarket Glock trigger or components, so not sure if I’m missing out.

A "true" Roland either has a 10 cent trigger job or and Overwatch trigger.


I've been really happy wit my Overwatch NP3 trigger, minus connector and trigger block.
Link Posted: 5/19/2020 9:14:04 PM EST
I went with the polish job and added a Glock minus connector. I like it, for me I believe it is in that sweet spot for carrying.

Has anyone had issue with rmr type 1 battery drain? I had issues with flickering so I bought a battlewerx sealing plate, didn't fix it. Did the ATEI mod where you bend the contact and that fixed flickering issues. Unfortunately in doing so the battery lasts about 2 months. (even when off)

Had the G19 Roland for a few years now.  Just finished the G23 recently and haven't had a chance to shoot it yet.  Both had frame and slide work done by ATEi.  The stippling work has definitely improved judging by the work on both guns.

So I bought a Safariland 6354DO, thinking it was the right holster, but it doesn’t fit. I removed the bbl plug, but the comp is still interfering with seating the gun fully. I’ve never modified kydex before, so what the best way to make this work? Heat it up?

Since you have to re-order, you should go for the more modern and widely compatible Safariland RDS holsters (6390).

I've owned both and sold the 6354.

The DO was made for the Doctor Optics MRDS, the new RDS models fit a wider range of MRDS.

Mounting holes on the DO are higher on the holster, making it ride much lower than I prefer.

The newer versions have better designed MRDS shroud as well as a cover to help keep stuff off the lens.

Is the cycling issue just for some folks? Are there any people out there running comps with factory springs shooting cheap 115gr ammo? Or does this Roland setup require +p ammo?

After reading people having cycling issues I’m thinking I should just get a couple 13lb recoil springs now. What springs are you guys running and what do you guys recommend for the gen 5?


Thanks in advance.

Let me know if you have any issues with the SiCo/PMM combo.  I had the same setup in my G45 and I had to ditch it due to feeding problems.  I think the problems are from the barrel itself though.  The KKM combo ran great in my 10 with any and all ammo I put through it.

I really think the most honest answer is "it depends". Some people swear their Roland's run 100% with stock springs and 115 ball. I know mine didn't (Gen4).

Went down to a 13lb ISMI spring and it's been quite reliable since. Every once in a blue moon it'll fail to go into battery, let's call it once or twice every 1000 rounds. I won't carry it, but IMO that's not really the point of a Roland anyways.

Thanks for the feedback. I think I’m going to just grab a 13lbs spring now so I don’t have to wait another 2 weeks after I find out it doesn’t cycle with factory recoils spring, cause I hate waiting for stuff.

Is this the part I would need?

Everything from WWB 115gr to 147gr competition loads.    At first I thought it was the comp causing problems but it looks like the issue is the barrel itself.   Others have had similar problems

I have PMM, Killer Innovations, Agency Arms (Single Port & Dual Port) and KKM comps on my Glocks and all run 100% shooting 124 grain and 147 grain loads.
One thing I’d like to point out is, you need to break new barrels in with 200-300 rounds before installing your comp. I’ve done this with all my pistols and have never had an issue.
9mm NATO is my favorite cheaper load but is impossible to find right now.

ETA Stock recoil springs in all

What’s the weight of the 9mm NATO rounds? Is there a specific manufacturer you favor?

Btw what Glock are you using for your PMM and KKM comps?

Yep, that's the exact guide rod I have on mine. It works perfectly, just find the spring you prefer and use some locktite on the screw which captures it. It'll come loose under recoil otherwise (it's a very tiny screw so you can't put a lot of torque into fastening it).
