The problem is many, many people with carry permits never practice. I was in a required class for a permit in Nevada and there was an older lady with a S&W .38 special revolver that she said she owned for 30-years and had never fired it once...in fact, she didn’t even know that is was a revolver.
I attended a one-day combat handguns course at an academy and it was a fantastic cours. 400-rounds in about 5-hours with many under-loaded magazine reload drills and shoot-no shoot course with walls and doors and life-sized human photo-targets.
I try to shoot at least once a month.
Cheers and keep your finger off the trigger.
For practice, knowledge, proficiency and fun, join in IPSC shoots. Widely varied scenarios, lots of shooting at varied targets, movement, anticipation, practicing application of skills, pressure in the form of competition and speed and just the camaraderie make it a great day. You don’t need to be good as all skill levels participate - but you will get much better with the practice. Go simply watch and you will be hooked.
