Thread Pitch Information
We get a lot of questions about thread pitches and what we use on particular barrels. Glock barrels are available in two types of threads: Suppressor Threads and Compensator Threads. These differ in a few ways. Our suppressor threaded barrels are available in common suppressor adapter pitches like:
1/2×28 for 9mm and .357 Sig
9/16×24 for 10mm and .40S&W
.578×28 for .45ACP
These barrels also have a longer distance between the end of the slide and the start of the threads. This accounts for guide rod interference when using certain suppressors.
Our compensator barrels are threaded:
9/16×32 for 9mm and .40S&W
5/8×32 for 10mm and .45ACP
Using this thread pitch allows us to get the compensator as close as possible to the slide. This wouldn’t work for a suppressor as the guide rod would hit the suppressor. As you can see, these are not interchangeable.
Our M&P barrels are available in the above mentioned suppressor threads as well as Carver comp threads if you plan on using a Carver Custom compensator.
1/2×28 for 9mm and .357 Sig Carver Comp Threads
9/16×24 for .40S&W Carver Comp Threads
Can you thread a barrel .575 x 40 to fit a EGW cone style comp? And also do you make Wilson/Nowlin ramped barrels?
Charlie-
Yes we can do that thread but would need to have the comp you plan on using her and yes we make Wilson/Nowlin ramped barrels.
Can you thread a 1911 barrel for tungsten sleeves?
What thread pitch is the sleeve? How far back on the barrel would we need to thread?
