Thanks Patrick and Kyle. I am going to try the weaker magazine spring. I never would have thought of that one. The '3 inch carrier asembly' is certainly a new one on me. Does this part work as a parts interchange to the 11-87?
I know what is happening I just don't know why it is happening. I have spent a bunch of time working on it. I admit it, I am wierd, these little mysteries fascinate me. The strange thing is that my 11-87 works 90% of the time but two other 11-87s don't. I know of two 1100s that work, two that don't and wierder still other 1100s that works properly every other shell. Sometimes yup, sometimes nope. Same ammo, same technique.
JP did tell me what I suspected was true. Both the 11-87 and the 1100 are designed to load the chamber and NOT pause with a round on the lifter. So did they not work when delivered and the customers just never knew it was broken to begin with, or did they wear out and the customers never noticed the change? Both explinations seem strange, but as I said many owners are not even aware of it till I point it out. Then they look at me like I cursed their gun. Ha. Not the best way to make friends. 'Hey, can I look at that . . . '
As common as it appears to be, someone must have noticed and cured this by now.
