I got in to the sport of 3-gun because I'm a generalist rather than a specialist. In other words, I don't do anything particularly well, but can get by in most subjects that are shooting-related.
One of the best ways to improve our skills is to break each aspect of the sport into its component parts and focus intently one area, then compare our performance to others in order to discover just where our weaknesses lie. The downside to this is that our screw-ups are manifestly obvious to those around us, so if you're a shrinking violet, prepare for a little discomfort.
I got the chance to assess my pistol skills last weekend at the USPSA Area 2 Championships at Rio Salado in Arizona, and boy, was that an eye opener. Rio is probably the best pistol club in the country, and you can't throw a stick in any direction without hitting a half-dozen Grand Masters, so at any competition, the field is very, very deep, and therefore an ideal venue to absorb information.
I was squadded with Eddie Garcia, Nils Johansson, Muneki Samejima and Cody McKenna, among others, all of whom achieved super-ninja status years ago and are great guys to boot.
Anyway, here's a video of some of the stages, shot by my team mate John McClain, with all my ugly mistakes in evidence.
