My model 11 project gun has got me pretty depressed and just sorta wanting to give up on Semi Auto shotguns for good. Finally got it running with the 30 inch barrel, got the short barrel trimmed and ready to go and the cycling issues are back. Meanwhile, my pump guns run like champs. My Mossberg 930 home defense is a project gun foundering in the safe, can't find magazine extensions for them right now due to all the gun craziness (haven't really looked lately, can't afford to anyway). Thinking of just slapping that 30 inch full choke barrel on, put the wood back in it's place and let it rot in my safe. It bit me on the finger today.
