I've been running the same kimber 1911 in .45 for nearly 20 years, in competition and as a daily appliance.
Excellent on the IPSC course. Very handy everywhere else.

Are you allowed to go multi caliber?
The 1911 is easily adaptable from .22LR out to .460 Rowland with many choices between, all from the same pistol.
