This is the only Kimber, and in fact the only 1911 I have ever owned so I don't have anything to compare it to. When you go on brand specific forums you see people voicing the same complaints about these pistols from all three makes: Kimber, Sig, and Colt.
I fired the Micro some more yesterday and I think the mag drop problem is caused by my grip shifting when the pistol fires. It is definitely more common when you fire stout ammo such as Fiocchi or warm reloads. The mag release is quite close to the trigger guard, and if I put too much finger on the trigger I think the pistol can shift just enough to cause my finger to bump the mag release. I intentionally fired it with a firm grip and not as much finger on the trigger and the problem did not return yesterday so hopefully that is all it is.
Another thing I find is that the Micro likes ammo on the hot side. The most accurate load I have ever tried is 3.2 grains Bullseye with a 102 grain lead round nose. This is a pretty warm load, a little above the published max in most manuals, and not something you would put in a cheap pistol other than Hi-Point. The Micro makes neat cloverleafs at nearly perfect point of aim with this round, whereas with lesser charges it shoots a bit high with more spread. It also shoots the Fiocchi 95 grain FMJ quite well, which is what I use for carry in this pistol and my Glock 42. I have also put the Wolff 12 pound Colt Mustang recoil spring in the Micro. This spring is one or two pounds stronger than the rather squishy OEM Kimber spring and seems to absorb the impact of stout loads quite well, it also does a much better job of keeping the brass under control.
