Looking into putting together a gun for play and maybe a bit of 3 gun. I've found a couple of 1100s and I'm looking hard at the CZ 712. I know people are gonna say Benelli but I don't want to sink that much into one. Is there one of the Beretta models that will take mods such as a mag extension that I can get reasonable. I like a Beretta, I shoot an A400 Xplor Unico. I just figured for the price, an 1100 or a 712 should fit the bill. Any reccomendations, opinion or snide remarks are encouraged.
