I'm a moderately active pistol shooter. In the last two years I've taken two three-day handgun courses, one with Todd Jarrett at Blackwater and one with Louis Awerbuck here in Indiana. Over that time I've participated in maybe as many as a dozen bowling pin matches. I get to the range once a week and, given the confines of the range rules, attempt to maintain proficiency with basic skills, such as strong- and weak-hand only drills, reloads, and suchlike.
However, this stuff needs to stay current. Due to a confluence of events, I only hit the range once between the middle of January and last weekend's range trip with Caleb. It showed. Especially on the draw; you can practice the motions of the drawstroke "dry" 'til the cows come home (and I do need to get more use out of my blue gun...) but it's not the same as shooting from leather with live ammo, which I hadn't done since the Awerbuck course last summer. Time spent with .22 trainers is valuable for sight alignment and trigger control, but it doesn't simulate recoil control with the full-size pistol, which is a major component of rapid-fire shooting.
I seriously need to make a point of trying to get out to Wildcat Valley with Shootin' Buddy at least once a month, or else get a membership at MCF&G here in town. Or both.
Standing in a booth in an indoor shooting range is training for a pistol fight the way sitting in your garage and moving your car's shift lever around with the engine off is training for Le Mans.
