As to where it was made, mine says "Irwindale" on the slide, otherwise I would have no idea. Mine has been reliable with all ammo except the Winchester Dynapoint. I did have some failures to feed with the CCI 30 grain TNT. They have a really huge hollowpoint and it would sometimes hang up on the left side of the chamber but I switched to another magazine, got three with the gun, and the TNT's began to feed just fine. I've tried CCI in 30, 40 and 50 grains, Federal in 30, 40 and 50 grains, Remington in 33 and 40 grains, Winchester in 34 and 40 grains, and Fiocchi 40 grain HP's and SP's. All were reliable and accurate but I've settled on the Fiocchi soft points because they were about as accurate as any and less expensive than any others except the Dynapoints which are about the sorriest ammo I've ever seen.
