1. SigSauer P220 45acp - Older Style West Germany:
In my opinion, the BEST 45acp. Probably one of the best semi-autos overall. And one of the best companies. Accurate, dependable over any others, reliable, and WILL shoot anything you give it. Some 45acp; especially in the 1911A1 world, you pay high price for reputation and name. With the P220, you are paying high price totally for quality.
2. S&W Model 13-1: Same as the model 19 except fixed sites instead of adjustable. One of the smoothest and most accurate guns I've ever shot. It's served military and police officers admirably for years. Definitely one of the best.
3. Walther PPK 380. Not a mouse gun. They fit FULL in your hands; all the way to the bottom of the pad of your palm. They fit so perfectly. Yet they can be concealed in your front pocket if needed. There is no reason for a mouse gun when you can have the Walther PPK with a longer barrel, yet still able to conceal. Of course, they do cost a little bit. I will probably buy a 9x18 version, probably an FEG PA63 just to have another perfect feeling; never jam, and very accurate personal defense weapon.
4. Springfield Armory 1911A1 Mil-Spec 45acp: Mind you, I emphasize SPRINGFIELD ARMORY. NOT all 1911A1 are equal. And I believe that this model; especially if you can find the older models from the mid 1980's; was the best of the best. Better than Colt and better than the newer ones even by my beloved SigSauer. This 1911A1 was accurate, reliable, feed almost anything. It was excellent. A little big for carrying; but for those who don't mind shoulder holsters, they worked fine.
5. Hungarian AP-MBP 7.65 (32 auto). Modeled after the Walther PPK. I carry this one as my concealed when the Sig P220 isn't practical. When shooting the correct ammo, it's indestructible and as reliable as they come. My theory is; European guns: Buy European ammo. American guns: Buy American Ammo. When I feed Fiocchi or Sellier and Bellot into the FEG, it always fires reliably and accurately. I will probably buy a 9x18 version, probably an FEG PA63 just to have another perfect feeling; never jam, and very accurate personal defense weapon.
6. Ruger Blackhawk 45LC: It's a traditional single action 6 shooters. it can handle HOT LOADS which make it great for hunting. Better than a 357 magnum and about as good as a 44 magnum. It simply feels like a "Real Gun" is suppose to feel. Definitely not a concealed weapon. But when it's on your side, it feels right. And Ruger's reliability is a bonus.
I really don't want to stretch the last 3 spots. Not that I can't think of any that I like; just that those above are just so good that the rest would just be fodder. I will say however that I have NOT YET found a polymer gun that I liked; felt right; or was comfortable. Not like a gun should be. That includes Glock as well as Springfield Armory XD. And I've also never found a 9mm, 40sw, or 10mm that I've liked and would buy.
Forgot to mention: Depending on what I'm wearing; I carry either the sig P220 45acp or the walther or FEG 32acp. And for home, the primary handgun is the S&W Mod 13 357 magnum; with the P220 strategically locally elsewhere if needed.
