Hey Fella's
For myself...
When carrying in possible harms way
A service sized pistol or revolver with at least one reload, and usually a second small revolver/pistol with it's own reload. My theory is in case of a malfunction of my pistol. TAP-RACK-BANG drill... That fails drop the mag and insert my spare. And TAP-RACK-BANG. A complete malfunction then transition to the second gun. If carrying a revolver ... well I've only had a revolver malfinction once, and that was my fault. But with a revolver I'd probably transition to the second revolver before I'd re-load.
When carrying within my own comfort zone
I carry one small revolver, or pistol with at least one reload.
Perhaps my experiences have made me somewhat paranoid, or overly sensitive to dangers both real and imaginary. My philosophy is that doo-doo happens when and were you least expect it. And the people who bring the doo-doo may not look like I expect them to.
