OK, you CAN NOT buy an auto loading 3.5 inch capable shotgun and expect it to reliably fire and cycle 2.75" target loads. I don't care who makes the gun and what they claim the one you purchase may not cycle light loads. If you want htis ability then buy a pump.

Gas opersted firearms require a certain ammount of PSI for a certain ammount of time to fully cycle the action. The pressures generated inside the barrel must be signifigant enough to overcome the weight of the moving parts of the action from the gas rings ro the bolt and also overcome the opposing forces from the return springs. A 1 or 1-1/8th ounce target load does not generate the same ammount of pressure for the same duration of time as does a 3.5 inch goose load.

However they should handle loads of 1.25 ounces and heavier. But the 1.25 ounce loads may still give you some trouble every now and then.


AS for the two guns the 1100/ 1187 has been around for a long time and they work reliably if you maintain them properly. Which means replacing the gas rings periodically and keeping the gas system clean. Gas guns don't work well when they get caked up with carbon deposits.

I have yet to go into a 935 so I can't comment on that one.
