The sun came out today and I was able to take a break from unpacking to test drive the little Kimber. Distance was 18 feet, ammo was some cheapo Maxxtech FMJ (Combloc production, fairly accurate but dirty). I'm pleased to announce it did not disappoint. Function with this dirty ammo was 100% and within a few mags the Micro was shooting almost as well as my Glock 42. I tried a couple mags of Remington FMJ and accuracy was about the same but ejection and recoil were stronger with a small fireball coming out of the muzzle.
The only thing I might change is to go with a solid black rear sight was this would match my Glock 42, which has an OEM white dot front and Ameriglo flat black rear. So far very pleased with this little pistol and look forward to trying my reloads in it.
