I have an m11 9 but I'm keeping it. Just seeing which variant you are looking for. Could keep my eye out for one. The m11/9 is probably the most versatile out of the bunch.
They arent MAC's but I do have a couple subguns for sale including an suppressed sterling on a form 3. I can get a MACtransfered in on a 3 but it would be from out of state. Give the shop a call at 337-706-8638
