I'm now thinking of maybe getting one or two more, not for carry ... but as something for the range, maybe my wife, and because I like interesting guns (it's why I bought a Browning 9mm BDM, Daewoo P51 and Swedish Lahti).
So, I'm wondering what I might look for in a .380 to go with the Sig.
Sounds like a worthy endeavor. Perhaps the following list may be of use. In the descending order of desirability (for myself):
#1 Beretta 84F. The 83 might be interesting too, or, actually anything in the Cheetah family.
#2 Erma KGP-68A. I know that some people pan the Erma's quality, but this is certainly a distinctive gun in .380.
#3 Taurus Model 380 UL. It's pretty cute... Unfortunately, the force of the mainspring on it ruins all the fun, and my attempts to lighten it were not successful. Also, Taurus' stock clips have a rather short service time, and aftermarket is absent. At least you can fit Model 85 grips on it.
#4 Browning 1911-380. Unlike, say, SiG P238, which is a copy of Colt Mustang, the Browning is a scale model of 1911A1. Even has the miniature mainspring housing and grip safety. Unfortunately, it's not particularly faithful inside, although at least it uses a locked breech operation.
#5 Colt M1908 Hammerless - the gun that started the .380
#6 FN Model 1910 - I think it was even more popular than the Colt back when Teddy Roosevelt was President. See also Browning Model 10/71.
#5 Remington Model 51. Need I say more?
#6 Seecamp LW380. It has an unusual delay mechanism, which relies on deformation of the case, so it may be unfriendly to reloading. But it's definitely the smallest.
#7 Beretta M1934 Corto. Now, of course, Beretta 84FS is so much better in every possible respect, but if we start talking about .380 antiques...
#8 Llama III-A, or Especiale. (but not Max)
#9 SiG P290RS just for fun.
#10 SiG P232
#11 Sphinx AT 380-M. Now this is very magical and only goes on this list so low because there's basically no chance to find one anymore.
#12 Taurus Curve with laser - although I heard it wasn't a particularly wonderful gun...
Here's a list of other .380s, which do not interest me personally, but may be of interest to you:
- Walther PK380. Sure, it may fit your hand well, but the quality is reportedly Umarex, that is to say "low". Just buy Browning 1911-380 instead.
- Walther PPK & PPK/S. An iconic gun, but SiG P232 is better.
- Makarov Izh-70. Since it's not a service weapon, it has not collector value, except perhaps as a memento from 1990s and the hopes for friendship and cooperation between the superpowers. Those were the days. Otherwise, it's worsened Makarov with adjustable sights.
- Kahr PM680/CM680/CT680. I already had my fill of Kahrs. Good thing "T680" does not exist in their line-up, or I would be very tempted.
- NAA Guardian. The nastiest recoil this side of BFR.
- RIA 51912 Baby Rock. Just what kind of criminal builds a 1911-lookalike with blowback operation?! Even Walther and Browning used locked breech. Come on.
- SCCY CPX-3. Wake me up when it's actually available.
- Micro Desert Eagle. Points for the unusual gas-delayed system, like on VP9. But I heard it's a terrible gun, as far as guns go. Bad trigger, heavy recoil. I may be wrong.
- Savage 1907/1915/1917 in .380. Impossible to find, supremely expensive, and completely useless. An interesting antique for sure... I may get to it once I have my Model 51.
- Kimber Micro. Too modern and too practical to collect, and loses to SiG P238 in usability, as well as price.
- Vz.61 re-chambered into .380 by Czechpoint.
- Browning BDA. I would rather have an actual Beretta.
- Jimenez LC380. You know, this is kinda tempting in a perverse way. Walk into a poorly lit pawn shop, walk out with the most reasonable, reliable, and durable of Jimenez guns. But ugh... no.
- Beretta Pico. lulwhut
- Bersa BPCC. A service gun on .380? Oh my cookies.
- CZ-83. Quality guaranteed, but you have to love CZs. Also, good luck finding one.
- Grendel P-12. This is a historic curiosity for sure, but I'm not
that much fan of George Kellgren to pay the asking prices for it.
