I have two threaded barrels for sale: First is a Lone Wolf Glock 23 .40 to 9mm conversion barrel with 1/2x28 threads. Has less than 50 rounds through it. Very accurate and in nearly new condition. SOLD! Second one is a Sig P229 9mm threaded barrel with less than 50 rounds through it. It fit really snug in my 229 when I had it and may need fitting. Super accurate though. Has 13.5x1 threads, and I have a matching Silencerco piston to go with it if interested. $160 Sorry for the crappy pics, I can probably send better ones if needed.
