If there is too little shoulder to function with a traditional 1/2-28 interface, the special will muzzle face index.  So technically the special could work on all barrels, but the shoulder is better if you have it because muzzle faces are more likely to have dings, burrs, or to be carbon fouled.  Those issues can complicate installation.

Thanks.

On the Browning, maybe the barsto slows your unlocking or the can has less backpressure.  Nice looking BHP.  The custom BHP is a nice looking pistol.

Yes, use one of the Cam-Lok Carry Comp.

We didn't specify a torque value to that, I would recommend very lightly snugging those with a wrench, the required torque is ~1.5 foot lb or about 18 in/lbs.  If you hold the 11/16 wrench with a short grip with your thumb around the open end you should feel something like that same squishing feeling of the taper engaging that is felt with the silencer, and that will indicate the comp is mounted correctly. It is very low torque, but it's more than you can put on the comp with your fingers, and that's why the part has wrench flats.

According to the Air Force https://apps.dtic.mil/dtic/tr/fulltext/u2/283347.pdf  Hand torque on a 7/8" knob is 3-6 in lbs depending on the amount of grip afforded by the knob. It's not an exact correlation, but it shows you won't be likely to achieve adequate torque with fingers on the ~7/8" diameter part.

.578x28 is a muzzle face indexed thread, the Beretta 92 is good to go.

I have an epic Safariland holster, but then found it wouldn't accommodate suppressor tall sights on my G17.  Those Trijicon sights are perfectly regulated to the extent I can go like 1 out of 2 on full size IPSC steel at 250 yards offhand with high velocity 124 grain ammo.  It's too bad the holster doesn't fit the sights. Except for the flexible (not rigid) rail for mounting IR lasers, the G17 is an incredibly effective platform.

I'm sorry you had issues with the system.  

Please contact our customer service via our website.  The CAM-LOK adaptor style will dictate what is needed to check- if you got the special, that will require a check of your barrel muzzle face- often times the barrel muzzle faces have thick carbon or dings (which can deform material proud), or can have chamfers so big that the barrel face is a bladed edge of material, and those conditions can effect your mounting alignment because you need perpendicularity and flatness of ~.0004" or better to have good alignment happen.  

If you got the 1/2x28 standard that would be like a normal 1/2x28 piston in how it locks up on the thread shoulder and then would bring into question the piston and adaptor and would warrant at that point shipping the can and barrel for a customer service inspection to trouble shoot that.  That is an option in either senario- shipping the can, parts and barrel to CS to let them look at it.  We sell swiss CNC turned and ground alignment rods, so they have those handy for inspecting alignment.

I think install torque recommendation is 20ft lbs. I wouldn't expect that to be a determining factor in a problem though (overtightening).  Overtightening on a barrel face is probably not the best for a barrel with a thin bladed edge of a face.  

It also sounds like you may have really aggressively tightened the suppressor on the camlok adapter.  Very few end users have had issues with over-tightening (popping the adapter through the threaded area to the un-threaded area).  You should have no trouble getting the can off if you install it with moderate torque almost like the torque you would use to put the lid on a 20 ounce soda bottle.  The pistons aren't very thick because there is very little room to execute this system, and you can actually temporarily very slightly deform the piston at the unthreaded areas like squeezing a spring-tempered tube in a trianglular fashion, by over-tightening the piston if you are quite strong.  That allows the ID thread to change shape slightly and effects the tolerancing of the system in ways that could in extreme cases allow the threads to pop through engagement.  

Overtightening shouldn't effect alignment, because it doesn't put the device out of alignment.

About the only other thing I could think of that would result in the suppressor falling off, is meshing the threads somewhere that doesn't cause taper contact.  There are like three or four threads, so they could be meshed in a different area, but that wouldn't result in the system getting "tight" while turning it.  Turning through to the next thread could cause a temporary stop as you run into the next set of threads, but it wouldn't be "tight" so the ability to perceive that as a false positive is diminished pretty severely.

We finished manufacturing restock CAM-LOK® adapters and added 1/2-28 smg/pcc barrel adapters compatible with .630 length threads, and 1/2-36 smg/pcc barrel adapters.   That machine turned over from CAM-LOK­® barrel adapters now to standard 1/2-28 three lug barrel adapters.  


Those parts are headed to nitride and should be available soon.  

We’re going to be running pistons in a few weeks and will eventually make CAM-LOK® fixed mounts also.  The machine we’re putting those into is running SDQD suppressor rear mounts right now, but should be done soon.

They did start machining those a few days ago.  We had a 5 axis machine occupied with charging handles for a long time and that cost some ability to keep the 365 barrels in stock.  They should be about 3 weeks out on account of Nitride.
