Kimber Compact CDP I in a Spark's VM2. Have not found "The" defensive round for it yet so am carrying hardball. Tried Remington Golden Sabers but the Kimber hated those. Will try HydraShocks next probably.
Edited to add: Just ordered 500 Winchester Ranger RA45T for "trial"! Thanks AZ Husker!
Kimber Pro Tactical, series 1.5 for all day carry, Kimber Gold Combat series 1 for shorter spurts. Both in a Versa Max II on a Sparks belt, CM Powermags with 8 rounds of 230 gr. hard ball. Spare mag and Shurefire E2e in a Brommeland combo pouch and usually another mag in my back pocket. Ready to rock 'n roll!
