It's not a single action RAP.
The Springfield Armory "Firecat" is nothing more than the Astra A-70, produced by Astra in Spain for Springfield Armory. Kinda like the XD is nothing more than the HS-2000 produced by IM Metal of Ozalj, Croatia.
The big difference is price - both pistols, when marked with their original manufacturer's markings are relatively inexpensive. SA jacks up the price to appeal the American notion that "if it doesn't cost a lot, it can't be good," and there you have it.
The Astra A series are excellent pistols. I have an A-100 in .45 ACP, and it's one of my favorites - accurate, reliable, and comfortable to shoot. It will give any SIG P220 a run for the money, not least of all due to its 9 round magazine. . . If you can get any of them (A-70, A-75, A-80, A-90, A-100) at a decent price - SNAP THEM UP.
