Way back when, I had one of those AMT, backup 380's. It wasn't a terrible gun just a little too heavy. It did have one bothersome problem though . . . the safety bar pin used to break off at the rear where it went into the frame. Mine broke at least twice that I recall. I ended up selling it to another guy on our department. Now a days, I carry a Sig 238 with Hornady critical defense (90 GR) ammo. It carries and conceals nicely.AMT .380 Backup old single action.
I have some 115gr JHP +P. It's from back in the late 80's and isn't made any more. I bought them at a gun show in Dallas.
It doesn't expand much, about .40 to .45" but it has decent penetration for a .380.
It's WAY overpressure and I've never fired too many of them. Huge Blue Dot type muzzle flash. Got about 35 left out of a box of 50 rounds.
Personally, I tend to strongly agree. I even stoke my G-21's with 230 grain FMJ ammo during the winter months.At the end of my certification course, this
was on a list of several books that our CCW instructor gave us.
After reading it, I'll be sticking with FMJs when I carry my .380
Assuming that you read the book, it looks like you took away a lot of what I did.Personally, I tend to strongly agree. I even stoke my G-21's with 230 grain FMJ ammo during the winter months.
To answer the OP's questions: It doesn't really matter; and I don't really care; but, I've been using Magtech 95 grain FMJ in my 380 auto. At the moment, though, I'm using Fiocchi, 'Extrema XTP' cartridges with 90 grain JHP heads. I got a good price on a lot of this ammo; (in several different calibers) it's nice 'n hot and blossoms ....... OK. Not great, but, OK.
I occasionally carry (weddings and funerals) a German-made Walther PPK-S that I've owned for the past 35 years. In 4 or 5 hundred rounds it has, never once, jammed on me! Austin Behlert did an action job on it, and SS Armoloy-plated it for me. It's a nice little pistol and carries well underneath lightweight suits and Summer wear.
(I don't lose a lot of sleep worrying about what I've got in either my 32 or 380 autos. Wait until you're close; shoot straight; empty the clip; go for the head, and you'll be fine. Which, now that I think about it, is probably, 'Why' I always carry one of these guns with three full magazines - I consider them to be, basically, 3 shot pistols!)
