I don't carry outside the home often, only a few days a month (it is nearly impossible to get a CCW permit in MD, though I am in DE and VA often and carry when outside MD on a non-resident UT permit, and soon I'll get a non-resident NH permit so I can carry in PA again, and I'm there quite a bit). I do often carry around the apartment for quick home defense. There are only slight differences in what I have in my holster at home v. when out of state where I can carry. I have been a part-time carrier (outside the home) for some years now, and I've carried at home for 15-17 years now.
I've gone through several options that I don't carry anymore:
-My S&W 65LS has been carried a little in a cheap Uncle Mikes IWB holster early on. I love the gun, it was my 1st .357mag, it is in great condition, and it is out of production so I don't really like carrying it anymore (I'm afraid something may happen to it). I also prefer carrying guns that aren't too expensive ($600 and under) just in case. I do still sometimes load it up for home defense (though I don't carry it at home since I don't have a good holster for it)
-My S&W 1911PD. I love 1911s and it is a Lightweight Commander sized gun. I stopped when I started only carrying guns with no safety and a DA 1st shot. It is also expensive for carry (for me).
-Bersa Thunder. Sold it years ago, too big for a .380.
-Taurus 85CH. I go for larger capacity most of the time now
-S&W 442. Capacity is too low
-Ruger LCP. Capacity and I prefer a larger caliber
-Taurus PT 140 Millennium Pro. It hasn't worked in years. Before that it lost the rear site (since replaced)
Bought with carry (partially) in mind but never carried: (some had some carry at home only)
-2" Rossi 461. Had issues early on and I don't really shoot it much or trust it as a result.
-3" Rossi 461. Due to the issues with the 2" it will need far more testing before I trust it.
-Ruger KP345. It wasn't reliable and I sold it once I got it working
-CZ 40B. Great gun, shouldn't have sold it, never had a carry permit while I owned it.
-Taurus 605. Great gun, but I never had a permit while I had it.
-SIG P229 (.40S&W). Loved it, but sold it when money was tight. Never carried it, always went smaller (PT140 or 85CH) the few times I carried when I had it
-Kel Tec Pf-9. Not quite as reliable as I'd like for carry. Not as comfortable to shoot as my other micro-9 (SIG P290RS). When I might carry it, I find myself carrying the SIG P290RS instead. I think I actually carried the Pf-9 on a VA day trip all of one time.
Bought with carry in mind but not yet ready to be carried:
-CZ P01. This is my newest gun and needs another range trip or two before I carry it (1st carry will probably be in a few weeks).
-S&W M&P40c. Bought it this weekend from Buds, once it gets to my FFL I have a week long MD "cooling off period" before I can get it. I suspect that once it gets a few hundred rounds through it, the S&W and CZ P01 will see almost all my carry time.
Current carry guns:
-SIG P290RS. I now like larger guns with higher capacity, but I love this gun and can't bring myself to retire it.
-SIG P250 Compact (.45ACP): Love it, great size. I often carry it at home and when visiting a state where I can carry. It may get retired for the CZ P01 and S&W M&P above for the greater ammo capacity in roughly the same size (P01) or smaller (M&P).
-S&W 625MG (.45LC): I rarely carry it out of the house (too big and heavy) but I do carry it sometimes (in an OWB holster and sometimes in a Galco Summer Comfort IWB). I often carry it at home or have it loaded for home defense in a quick access safe. Outside the home it gets the most use when camping in the woods.
Most likely to buy for carry in the future:
-3" S&W 686 Plus. Love revolvers, a medium frame 3" revolver is terrific for carry, I love the 7 round capacity (I prefer higher capacity these days, and that is nearly as good as it gets for a carryable revolver).
Edit: I missed at least one:
I also had a NAA Guardian in .32ACP for a couple years. I think it made it to VA in a cheap Uncle Mike's pocket holster once or twice. I carried it at home a lot since I can easily empty my pockets at home and carry it around. I never really trusted the caliber and sold it about a year before I replaced it with the LCP.
