Since this seems to be "The Thread That Will Not Die..." I'll jump in here.
I recently acquired a Firestar M45. Did a lot of research, some of it from lurking on this very forum, and even this particular thread!
Funny story, actually. Once I decided on the Firestar, I was lucky enough to find one at a local gun shop. Put in on layaway in early December, and went in shortly before Christmas to put some more money down on it. After much hemming and hawing the guy finally 'fessed up that my dad had come in the week before and paid it off!
Anyways, after a couple hundred rounds at the range, I've noticed a tendency for it to hang up fairly frequently. Seems to be a failure to feed. Don't think it's a limp-wristing issue, as it's happened to both me and my dad, and while i'm relatively new to handguns, he's been shooting them for 50+ yrs.
Ammo that it failed w/ was Hornady 185 XTP, Remington Golden Sabre 185, Blazer 230 FMJ Target loads, Winchester FMJ 230 target rnds, and Remington standard 230 JHP's. Only thing it seemed to like was some standard Winchester JHP 230's, but i only put one mag of those through it. those are obviously what i'm loading with for carry, but i still have my doubts...
Happens with a variety of ammo, even FMJ, so I'm thinking magazine issue possibly? It's a factory mag, maybe it's just tired, or could use a little porting/polishing?
Here it is, BTW:
And that is a FREAKIN" SWEET piece Grapeshot!
