I had a FEG PA63 in 9x18 some years ago. Aluminum frame. It was actually quite well built, reliable, attractive, and stupid light. Kind of what a Commie version of 007 might carry.
The thing bit. For a relatively anemic round, it was just plain unpleasant to shoot. The single action pull was very good, so fine accuracy was possible even with the nubby little sights...so long as you didn't flinch before the hammer dropped. I'd liken the felt recoil to firing a .357 Mag snubby with full power light bullet loads, only the .357 snubby has better grips, so the "bite" still isn't as pronounced. I was happy to sell it off to somebody who fell in love with it and didn't mind the setting an M80 off in a closed hand sensation. He actually thought that was cool, and a fun surprise when friends came over to shoot.
That's an excellent description of the PA63. The double action trigger pull makes most double action triggers on revolvers feel nice. The PA63 is a very close copy of the Walther pistol for sure. I still have mine though I don't shoot it much anymore. It is the last commie pistol in my collection now. I'm sure that I could double or triple my money if I wanted to sell it right now. I think I gave $125 after taxes for it.
