I have an arsenal converted saiga 12 shotgun, originally made by Izhmash in Russia. This shotgun has a billet trigger guard that takes an ar15 grip, Ergo grip, Ace side folding stock, Tapco G2 trigger with a very smooth and light pull, hi viz painted front sight, and quad rail. The 19" barrel is threaded for external chokes or muzzle brakes. It comes with 1 Izhmash 5 round, 2 AGP 10 round, and 2 SGM 12 round mags. The SGM mags will hold 13, if inserted on an open bolt. I tried all 5 mags and had no issue. I've fired 100 target loads and 5 rounds of buckshot through it so far. I had no issues. This shotgun is really fast. I have too many shotguns, this needs a new home. $1125 OBO. Trades 9mm, 44 mag/spl, 12 ga, 308 match ammo 9mm full size pistol Maybe something else? Let me know what you have.
