At least once every other week for a 200-300 round range session with about an 80/20 mix of target to carry ammo. I usually work on fundamentals and skills like reloading, malfunction drills, etc. In between while at home, I practice drawing from concealment, reloads on the move, weak hand manipulations, etc.
These days, I only own my carry pistol, a couple shotguns. Shopping for/deciding on another AR. In years past, I've had several handguns at a time but did not carry then. I strive to master this one pistol, this one caliber, and in doing so hope to stay alive longer. My investments are in ammo, targets, holster, belt, mag carrier and range time. Soon, more training.
Ruger SR9C, currently in a Galco KingTuk designed for the Glock 19, IWB, strong side between 4 and 5 o'clock. Soon to be replaced by an RCS Phantom with an FBI cant and the accessory double mag carrier. I use a cheap but effective knock-off Trainer's belt from Duluth Trading.
