The bolt is supposed to lock back when cycled manually. When you fire it with a round in the magazine the round trips the bolt and carrier.
Until you break it down and clean it completely, you can't diagnose anything else. I have a '63 and a '66 Model 1100, and they both are still going strong with the only part having been replaced being an extractor in 1982. The '63 has upwards of 115,000 rounds through it. I did change the metal V ring in the '63 to an O ring about 1967 so I wouldn't lose it. O rings are available on ebay for about $6 for four - delivered. I can't drive to the hardware store for that. You want Viton. My '63 still has the O ring I put in it in '67. They do not get damaged shooting, they get ruined by ham handed disassembly and assembly.
The old style piston and piston seal work better than the new style. They did cost more to make. If you ever do need new ones, Midway sells a Nu-Line clone set. Modern coil action and magazine springs do not wear out sitting either. I have replaced several that were very rusty for other people.
If you have lost yours, go to www.remington.com and download and owner's manual, and read it. Lots of good info.
After you clean it and try it come back if you need more help.

Re: Older 1100 12ga. repair questions.
Well, now you have known of it. I have owned 13 1100s/11-87s, and worked on hundreds of others, starting in 1963. The bolt is supposed to lock back when cycled manually. I currently have one that doesn't; the carrier latch is slightly bent. It cycles fine and I have been too lazy to change it.
The brand new ones have a small finger on the carrier so it does not lock back, to keep people like you happy I guess. It usually does not affect the normal cycling of the gun if it does not lock back.

Good job. I have owned about 30 semi autos and shot about everything made, and have yet to find one I like as well as an 1100. They are easy to keep going. You did good on the O rings too. People talk about going to the hardware store, and I can't drive to the store for that.
