I have one. With the stock springs, the DA trigger pull was about 50lbs, and recoil was like a .44mag. After swapping the springs, the DA trigger is still heavy but is now manageable, and recoil is far, far less. It's still not a gun you'd want to fire hundreds of rounds through at once, but there are now no problems with putting 50-100 rounds through it for practice.
I actually carried it the other day for the hell of it. It was certainly a lot more comfortable than my usual Springfield EMP (of course, 9mm+p ballistics slaughter any 9x18 offering).
Given that you can now get a pa-63 for $140, and do the spring swap for $10, I think it's a great value for anyone looking for a cheap but quality carry gun or "truck" gun.
