Re: Mini 1911's...
Some of my tiny 1911's are over thirty years old, the old Detonics Combat Masters, the oldest.
They have their own set of problems, due to the short stroke, and cycle time; the extractor, and breech face, must be perfect, for reliability, the recoil spring a monster, and frequently replaced, or you will beat the frame and slide to death; the 5" gun is fitted with an 18# spring, as standard, the Detonics runs best with a 28# spring, with 'full house loads'.
The magazines must be hard to load, ie, with a very stout spring, or they will tie up the pistol, as they have some less than half the time, in a 5" gun, to put a round up, for feeding, in a compact, because of the short 'cycle time'.
In the officer's model Colt, I would lose the recoil spring plug, and replace it with an Ed Brown, or similar unit, with a full length guide rod, as the stock piece has a high failure rate.
Ammo is critical; if too long, it does not have enough time to rise and feed, in the firing cycle; a critical step in putting the 'package' together, for ccw.
Lubrication ought to be grease, not oil, and my preference is Moly Disulfide grease, applied to the slide ways, with a toothpick, and sparingly, or you will see a lot of permanent grey spots, on your clothing.
Mags, again; while most of the compacts will run with a full sized mag, it better be perfect, with a stout spring, and that, only for practice; that same spring, in a short mag, will insure reliability, if it does not compress to 'coil bind' with the mag fully loaded.
I learned the tiny colts from the man who pioneered them, Armand Swenson, probably the most gifted pistolsmith ever to walk this earth, a friend, mentor, and all around wonderful man; interesting that I found this thread on Easter Sunday, the anniversary of another most wonderful man's death, and ressurection.
