I was lucky enough to have the opportunity to get a Service Grade on the first round and surprisingly I was picked for the fourth round. Since I had the service grade on the first pick, I went with the wild card of range grade.

Round 1:
Frame: RR
Slide: Colt
Conclusion: Mutt






Round 4
Frame: RR
Slide: RR
Conclusion: Mystery Gun

That second one looks like one of the Delta guns. Saw a thread about another one that someone got on 1911forum I think.

As far as #2-
I'll qualify this statement by saying "I'm not an expert."
But could be a early "Delta" one- Late 70's to mid 80's would be my guess. It looks to be put together by someone who knew what they were doing and not all ratted out.

It's not one of the MEUSOC .45's (M45), I know that much. They had a diffrent happer, extended ambi-thumb safeties, and different sights.

Either way, those are two nice shooters!
