I am ordering a Glock 17 threaded barrel from Gemtech to give one a try. Aftermarket barrels, without a ramp polish, seem to be a 24/25 \will it go bang' proposition. Hoping that the factory barrels will take things to the next level. The most reliable suppressor pistols for me have been the HKs. USP9, 45, HK23. They just never jam. There is something about a pistol that fires every single time. No matter if it is dirty or not. Hoping the Glocks can make it to that level with these factory barrels. Anyone have experience with them?
