I sent my Elzetta ZSM Tactical Shotgun Flashlight Mount back & they sent me a new one. I mounted the new one with strips of bicycle inner tube between the mag tube, barrel and the mount. This allowed me to tighten the mount a lot more before magazine binding would occur.
I took the shotgun to the range and fired another 50 rounds through it. The shotgun performed flawlessly with every shot. The light mount and flashlight stayed firmly in place.
The ammo used was 25 rounds of Federal 3 dram 1 1/8 oz 1200 fps loads
and 25 rounds of Federal 2 3/4 dram 1 1/8 1145 FPS loads.
The Federal 2 3/4 dram 1 1/8 1145 FPS load should approximate the recoil impulse of the Federal 132LE 00 with 9 pellets weighing right at 1 1/10 oz with a muzzle velocity of 1145 fps.
So far I have a total of 250 rounds through this shotgun with no malfunctions.
The trigger is breaking in and feels much better now.
I was thinking of putting a spring kit in the trigger but I think I will leave it alone. I still may put a reduced rate recoil spring in it when they become available but I am not certain. It seems to be functioning fine with lighter loads. I', thinking maybe the reduced rate spring might be insurance against malfunctions in the event I don't have the weapon properly mounted on my shoulder or I have a situation when I have to fire it from the hip or some other awkward positions. Anyone have any thoughts on this?
So far I am really pleased how this rig is coming together .
