Its a big misconception to think that most LEO's are well trained or knowledgeable about firearms. Most are not.
100% agreed. Most cops aren't gun guys.
The difference between most LEO's and most civillians is TRAINING. They may be complete fools with a gun in their hand, but they DO usually have FORMAL training, and the documents to prove it, which is a helluva lot better than the civillian who just got their first gun, their brand new CCW, they have 200 rounds a year downrange, and now they're carrying a cocked and locked 1911. Or worse yet ... carrying a 1911 in condition 2 or 3. Now they're fumbling to rack the slide (when most jams occur) or cock the hammer by hand (don't let it slip off your thumb), because even THEY'RE afraid of carrying in Condition 1, which is actually the safest for an experienced 1911 person. Can you spell recipe for disaster ?
Yeah ... we all know to keep our fingers off the trigger unless we're prepared to shoot, but if everybody's so damn good at gun handling, muzzle control, and trigger control .... how come there are thousands of mistakes made at ranges around the country every week. People with their fingers on the triggers with loaded guns pointed at people, people sweeping other people or the entire firing line with loaded guns, etc etc. Anybody who's ever been at a range has had that happen or seen it happen.
I've shot tens of thousands of rounds of 45ACP out of 1911's, and I won't carry one anymore. Not when guns like Glocks, LCP's, SR's, or P3AT's are available.
Bottom line .... carry whatever the hell you want to. Carry modified guns, with amateur kitchen table gunsmith work, carry reloads, change the springs (usually for no reason), put in fire control groups from aftermarket manufacturers ... whatever. Chances are you'll be just fine .... until you're not ....
