.45 acp LWD 2 port ss barrel for your g21/sf. put maybe 2 mags worth when i first got it and soon switched to a threaded barrel…so this one is just sitting in the safe. however, it did work well. it really kept the muzle down between shots aiding in faster follow-ups aswell as a softer recoil impulse. coulnt tell an accuracy difference between this and the g21sf OEM barrel…i tried but my accuracy results were about the same iether way. $100 shipped. email me at [email]kendapp@live.com
buyer also recieves 2 peirce +2 magazine extentions
