Been carrying concealed for about 6 years now, on-the-job off and on about 5 years total now. Been "playing" with firearms off and on for decades before that, since I was a wee one. Sorta shifted into firearms as a hobby as my interest in cars waned for awhile, and as a result of things I've experienced and things I've seen going on locally and nationally. Used to be that I freakin' HATED Glocks, largely due to their obnoxious fanboy crowd and because they feel weird in-hand; after getting a smoking deal on a G30 from a co-worker and giving it a fair shake, dang it, I found out that I actually shoot them more accurately than the M&P's and Rugers that I had preferred up until then. So, by and large, most of my carry pieces are Glocks. *hangs head in shame* I'm just another lousy Glock guy now. Dammit. Although I do still carry the occasional Ruger or S&W revolver now and then ... just because.
Main carry pieces are, in order of largest to smallest:
1. Glock 21 (usually open-carried to/from work, haven't quite convinced myself to swap in the 10mm conversion barrel for carry yet);
2. Glock 19;
3. Springfield XDS45 4.0";
4. Glock 26;
5. Kel-Tec P11;
6. Glock 43;
7. S&W 686+ 2.5"
8. Ruger SP101 2.25";
9. Kel-Tec P32 Gen1 (hard chrome finish, for summer);
10. Kel-Tec P32 Gen2 (blued finish, for winter).
I switch around my carry pieces from day to day, based upon what I'm wearing, where I'm going, and ... well, just whatever I fancy that particular day. Aside from the two wheelguns, they all have exactly the same manual of arms - no manual safeties, no DA/SA triggers. Some folks will harp on the fact that the revolvers aren't EXACTLY the same setup, but my default response to encountering a malfunction or running my primary gun dry is to draw my secondary, which is whichever of the two P32's I'm carrying that season in my back pocket. If I'm in a situation where I need to empty my primary AND my secondary, I'm already in a world of hurt, but I should at least be in a position by then where I have found cover and can reload without having to need Jerry Miculek-like speed to be effective about it.
As an aside with regard to the .410 rounds, if you're using ammo that's actually designed specifically for .410 handguns, the performance is MUCH better. For my S&W Governor, which pretty much only sees bedside duty, I prefer either Federal Handgun 000 buckshot or Lehigh Defense Maximum Expansion loads (which are .45 Long Colt loads oversized in length specifically for Judge/Governor/Bond Arms applications). The Federal Handgun 000 buckshot loads make fist-sized patterns at 10 yards in everything I've shot them through (full-size Judge, Public Defender, and Governor), and ballistic gel tests show them consistently coming in right at or just over the required 12" penetration depth. A third choice would be the Hornady Triple Defense load and, if none of the above are available at all, lastly I would opt for the Winchester PDX-1 .410 load (those BB's are worthless and spread too far too quickly, but the discs do okay). Using old-school .410 loads designed for full-length shotguns instead of modern handgun-specific loads usually yields the crappy results for which the .410 handguns have long been known. Use the right ammo for the given task.
