I ordered one of these 2 months ago to use with my Form 1 suppressor I made from one of the Chinese imported solvent trap kits. This was originally intended for use on my CMMG Banshee pistol. When I drilled out the baffles last year, I was paranoid about baffle strikes, so I made them sufficiently large for 10mm, even though I was only anticipating running 9mm through it. Heck, I probably overdid that, because I can nearly fit a .45 through them. But the can is 12 inches with 8 baffles, so I figured that was plenty of internal volume and restriction orifices despite the exit bore to be effective. Heck, other than the stamp, I'm into it for only $50 bucks, so I'm not gonna be anal about the performance.
I pulled the direct thread mount cap off and threaded it onto the StingerWorx mount. I didn't have a bore alignment rod/gauge, but knew my baffles were generously drilled and was willing to risk it. I'm happy to report that after nearly 900 rounds of 147 grain polycoated Blue Bullets over 3.9 grains of CFE Pistol powder, there have been no baffle strikes. And I looooooooooove this product!! I've been wanting to suppress my Sterling for sooooo long. It feeds funky bullet profiles better than my Uzi and just recoils smoother. Only my MP40 is smoother.
The Sterling has always been a crowd-pleaser with new shooters, but it is even more popular now. Nobody wants to put it down. Now I'm worried that my El Cheapo Form 1 can might simply wear out from use.
