I carry. Just want to note that if you start spraying lead you better be real concerned about where those bullets are flying. You don't want any bystanders wounded or killed. I have laser grips that I hope would put some fear into the SOB and maybe stop him in his tracks. But if I pull the trigger I know where my bullet is going. But misses have to be a huge concern. It's no different than hunting - you HAVE to know what's behind your target. Hopefully I never have to use my pistol.
My Kahr PM9 came with Crimson Trace laser, and I'm ordering a CT laser for my Sig P239. My XD/9 and S&W Sigma/9 have the cheaper Laserlyte lasers.
I never realized how helpful a laser was until I went to the range several weeks ago and shot with and without. Night and day difference.
Always a good idea though to be a decent aim without it, just in case it doesn't work when you need it or the sun is too bright to quickly see it. My stepdad is a retired 31 year PD veteran and taught instinctive shooting - I'm gonna work on that some.
A year ago I really wasn't into guns that much. I always owned guns, just never got into it as a hobby. Once I began going through the process to get my CHL I realized how much fun it is. I've also found it to have a lot of the same benefits that karate had for me years ago -- that being that they're two of the few hobbies where your skill can go with you just about anywhere and everywhere and be of use. I looked back at past hobbies, i.e., golf, billiards, flying, and realized that those skills were pretty much useless to me once I left their arena.
