For the first several hundred, I would be using heavier 124g bullets to get that recoil spring worked in. I had issues with 115g bullets on my Canik within the first 300 rounds as well. Pump some more through it and let things break-in. A tight fitting 1911 can take a little time to all mesh - but that's a good thing down the road.
I personally don't strip clean my pistols until after a 1000 rounds or more, there isn't a need. I do take a rag and either Ballistol or G96 with me to the range and simply wipe the barrel tip, the load ramp, and the magazines before putting back into my case to take home. Then I leave them until the round count gets up there. My revolvers I will clean the cylinder face better when I get home, but I don't ream anything down the barrel until over a 1000 rounds - there's simply no need and it prevents muzzle wear; I have seen some rifles that had minimal rounds down the tube yet the muzzle needed to be re-crowned as the owners cleaned the heck out of them after every time they took it out.
I wondered about the 1911's without the bushing as to how you pulled the slide. I came across this video, seems like a cool little tool.
