I have extensive experience with the Phoenix Arms HP22, but only with the long barrels, and I've even improved one when it broke. First the kinds of accuracy with a barrel that isn't moving around is excellent, at least it was for me, usually I shot stationary empty twelve gauge shotgun shells with ease at 25 yards, usually accurate enough for me never to have noticed anything bad. The magazine catch will wear out with excessive use, it's made of aluminum, and eventually the mags wouldn't hold in, so I took a allen wrench and slotted it and made a home made button to retain it. While I was taking mine apart and fitting up the new mag catch I squeezed the thin portion of the upper mag well and it cracked a bit, but crack isn't in a critical area or go anywhere, I mean, ya know the frames are coated pot metal. I modified the bs "have to put it on safety before mag removal", aint hard to do, the junk is under the left hand grip.
I've shot mine about 2000 or more rounds, I'm surprised it lasted as much, that little cheap stamped sheet metal plate in the back of the slide around the firing pin, its been cracked for about a thousand rounds. I have two five inch barrels for mine, three finger rest mags and two non finger rest mags, I never felt the need to have a short barrel for CCW. It's too bad they redesigned the mag followers not to have last shot hold open, but I guess it was done to be on the safe side against being sued by anti gunners.
Oh, forgot, nearly, that the slide return spring, it can get a little weak, maybe weak to begin with, I noticed a broomhandle mauser pistol bolt return spring was same size, had an old one with plenty of strength, maybe more, so I cut it to about length with more coils, more strength, and that improved stripping off rounds from the mags a whole lot better. Mag catch and slide return spring, the only two problems with these, apart from not being all steel, though when I bought mine, about twelve years ago, swear to God my gun dealer at the time fooled me into paying $170 with two non finger rest mags and the case, just seems they are the same price now or less, I no longer deal with that con artist dealer who still deals guns and gold/silver/coins etc usual stuff, he's the kind of guy who gave a poor little old woman $50 for a mint condition luger rig of her late husbands saying in front of me it was an old unsafe gun siince it was foreign made, and then price tagged it at $2500, she didn't even have a decent pair of shoes! That's right, the shame of it, I paid $170 over a decade ago, and I'm gonna make sure I squeeze every penny out of this pistol, its taught me alot.
