Selling a Glock 20 10mm to 40 S&W conversion match barrel. Didn't use it much except about 50 rounds. I ended up getting a Sig 229 in 40 and just threw this in the back of my drawer. I used it in a gen 4 glock 20, and it worked great. Looking for $140 shipped, USPS MO or Paypal F&F will work for me. First I'll take it gets it.
