On a fairly frequent basis, I get questions from friends or acquaintances who ask me what type handgun they should buy for personal and home defense and concealed carry. I usually suggest they go to a range and try out several different models to see what fits them, which they can shoot most accurately, etc. I also highly recommend they take classes that cover Oregon's laws, as well as proper safety and gun handling skills, and finally I recommend they train with both dry and live firing.
Invariably they will venture forth to gun shops or shows, where they purchase a gun based upon size, weight, cost and seller's recommendation. Upon getting home, they will load their new prize and stick it someplace handy. One friend went so far as to get CCW permits covering the majority of the Continental US, but has failed to participate in any safety and skills classes, nor has he fired his new Crimson-Trace equipped 5-shot hammer-less S&W J-frame.
At this point, I am backing off my willingness to share my knowledge and experience. I recall many years ago someone sharing the following wisdom; "Never teach a pig to sing; it waste's your time and annoys the pig."
