I have a low round count Glock31 in 357sig. It comes with 2 10 round mags, box, and paperwork. Also included is a Wolf 9mm threaded barrel, 12lb recoil spring, and a Wolf 3 port compensator. The stock 357 barrel has 20 rounds thru it. The Wolf barrel has less than 300 rounds thru it. It has the 3 1/2lb trigger bar installed, an extended slide release. I also have the RCBS dies to reload, and 500 or so rounds of once fired brass.
