Storm Lake Glock 31 barrel I put this barrel in my G22 so I could shoot .357 Sig. Barrel has ~50 rounds through it. I am also including ~50 rounds of .357 factory Winchester ammo if transaction is FTF in Houston,TX. $70.00 shipped or $70.00 with ammo FTF. In case you don't know. you can shoot .357 Sig through your Glock 22 with just a barrel swap. Everything else is the same including the magazines.
