Good afternoon. I've recently acquired a Benelli M1 Super 90 Tactical and want to put a pistol grip stock and side saddle shell carrier on it. This gun is in mint condition and I want it to be similar to my 870's for ease of operation. I know this is an older gun, out of production. But, does anyone still make these parts? Will M2 or M3 stocks fit the M1? Thanks very much!
