Before he bought 1100’s, my father shot a Sportsman 58 which had a very similar, if not identical handle. More than once, usually on a dove hunt, the thing would take flight and come up missing. As a little tyke, I was his retriever and remember on at least one occasion when we got back to the car, I heard some choice words 😁 as he tried to unload. I think he was able to use a key to pull back the bolt.
I haven’t had it happen with my 1100 but my brother has, so if you have an 1100 that likes to spit the handle it’ll pay to have a spare.
