That tactical 1100 will reliably cycle standard 2.75 loads IF you do some minor modifications to the gas ports. I prefer the 22" version with the standard stock.
FWIW there are several vendors on Gunbroker selling used Beretta 1200 FP's. They were the fore runner of the Benelli inertia guns and the best of the bunch IMO. If you want a boringly reliable semi auto self defense gun, that is it. Every one Ive ever handled worked flawlessly and digested everything you put in it. The bores and bolts are chrome lined and easily maintained. The majority of parts are intechangable with the Benelli M1 and there are still a ton of parts on the market.
