I've had problems with Wolf ammo on many guns, but my 9mm Taurus PT92 has been fed everything from fine USA manufactured stuff, to cheap Chinese and Russian ammo. (The China stuff was loaded for sub machine guns, and very hot, the Wolf Russian stuff barely has enough powder in some loads to get the gun to cycle...)
Round to round, the Wolf stuff is never consistant. That makes it pretty hard to shoot accurately with it, and unless you just want to plink/rock n roll, a waste of money in my book.
For the money, the pistols made in Brazil by Taurus are the best deals out there at the moment. The XD is nice, but it's made in Check, or Yugoslavia, so not really a USA gun anyway...
The full size PT is concealable, but I'm leaning towards buying another, smaller 9mm Taurus, perhaps the Ti version.
Light, best trigger stock out there, and the cost is very reasonable.
