No doubt there is surely a tactical benefit of CC vs OC, but I do truly understand that rights that are not used, are in jeopardy of being lost and can appreciate folks that desire to exercise those rights.
I have not looked up any type of 'stats' nor do I know if any even exist BUT ..... I really do not recall EVER hearing of a legal gun owner that was OC, being involved in situation of thieves running up and snatching weapon from holster. I just dont see that as an legitimate 'worry'. But make no mistake, if a bad guy is trying to take a gun from you, your life is surely being threatened and you DO have every right to use lethal force ...... as an LEO or civilian.
I totally disagree on the need for a safety, except for idiot. Idiots do not need guns of any type. For 32 plus years I carried without any type of safety as did hundreds of others I knew, without any problems. By removing revolvers from the list of guns you are removing THE most reliable weapon of all. Calibers surely matter. I much prefer to put 2 GOOD shots with .45 or .357 vs any 9mm or .380. You seldom hear of bad guy being shot 4-5 times with .45/.357 and living, but I have known that to happen numerous times with 9mm and less calibers.
