Since it seems like everyone has their own method when they buy a new 1911, what do you do? I usually detail strip the gun and clean it out. this will get any little particles out of the nooks and crannies. I check the extractor tension. I started this after i bought my EMP, whose extractor had a deathgrip on the ammo, which caused FTFeeds. I adjusted it at the range, and it's been good ever since. A lot of initial new gun issues could be related to the extractor. I used to treat the barrel with MilTech, but I'm out of it right now, so haven't doen't the last couple of guns. I usually make a slurry of FP-10 and JB Bore Compound to lo lap the slide and frame. I learned this from 1911Tuner on another site and it may be the reason why my guns seemed to run from the start. This also seems to reduce the "break-in" rounds that are needed for a 1911. For lubrication i use this I don't have a single favorite lube, but i do use grease on any part that slides and oil anything that pivots. Right now i use Slide-Glide Lite and either Wilson or Ed Brown oil. I don't clean the gun until after 300rds or so. The unburnt powder will mix with the oil to help lap the slide/frame. I think Wilson recommends not cleaning (only adding lube) until after 500rounds for this reason. For cleaning, I usually use Hoppe's, Butch's Bore Shine, a Dewey rod and jag. I only use a brush on rear occasions, but not often. I recently got Gun Slick foaming Bore Cleaner and it seems to work well. and i think that's it.
