I don't yet have a Micro, just got a Micro 9 and really like it.
I currently have a G42 and a P380. I have pocket carried the G42 for the last year. I shoot it as well as any gun I own out to about 15 yds. The P380 is my pocket gun when I am wearing slacks or something pant wise that won't accommodate the G42. The P380 has been very reliable as has the Glock, its long revolver like trigger and reset make it a challenge to shoot fast and accurately. As a get off me gun, it is excellent.
I carry Underwood +P 90gr XTP, about 1150fps from my OEM Glock 42 varrel, 1200fps from my Alpha Wolf barrel, which is my G42 carry barrel. The diminutive P380 still delivers pretty amazing velocity from these loads at over 1100fps.
