Twist rates and bullet stability are also very important when it comes to using silencers. Last thing you want is the bullet touching anything.

Glock and HK barrels use the same 1:9.84" rifling and Sig uses 1:10". Most aftermarket barrels use the slower 1:16" rifling. So basically stick with OEM factory barrels.
