Needed threads
I needed a hard to find .40 threaded barrel and this Silencerco did the trick for my Glock 22. Very fast shipping, barrel works, what's not to like.

Surprisingly great barrel
Purchased the Silencer Company threaded barrel for Gen 3 Glock 26 for obvious reasons. Was skeptical at first due to a narrower feed ramp than stock G26 barrel. However it ate everthing from Gold dots, FMJ RN, 115GR. -147GR. Whats more improved accuracy! A company known for Suppressors, they hit a home run as far as Im concerned with the treaded barrel for Glock 26. Well done.
