Mine hasn't ever cracked the frame, did the slide once, but they sent me a new one re-engineered. Got mine right after they came out and the slide was redesigned where the weak spot was.
Mine's UNREAL accurate. It shoots 3" clusters off a bench at 25 yards with the short barrel on it and CCI stinger. Pretty amazing and quite reliable. The 5" barrel feeds bulk pack Federal fine and shoots 2" at 25 yards. That's pretty dad gum accurate and useful in the field. I've slayed rabbits to snakes with it with just the 3" barrel. It's the only pocket carry I have that is worthy in the field for small game. Pretty amazing and why I keep it around. I hardly ever shoot it. I figure too much shooting and it'll wear out, being zinc and all. I have better .22s for plinking. I use it as a niche gun, pocket carry field use. NO it's NOT a high quality gun, but it has its better attributes and it was cheap. It's FAR, FAR more useful and a better gun than an RG I once had. Actually, it works FAR better than a Beretta tip up barrel I had, more accurate, more reliable. That Beretta was a POS and Beretta customer service is non-existent. I got rid of that one, kept the Phoenix Arms. LOL Jennings is junk. The HP has a hammer, I like that, and it's actually quite accurate. I've fired a Jennings, couldn't hit a paper plate at 15 yards with it.
I don't keep inaccurate guns, but it wasn't mine, belonged to a friend.
If I had to guess, I'd say my HP22 has probably 4K rounds through it, about half and half between the 5" and the 3" barrels. It wears a recoil spring out occasionally. Thing looks like the spring in a ball point pen.
But, the springs are cheap and available. I have a spare left when the one in the gun wears out. Don't know when that'll be cause I don't shoot it that often. I have a Ruger Mk 2, a Rossi revolver, and other nicer .22s I fire often, but the HP has its place. As cheap as it is and considering the decent accuracy, I don't consider it a waste of money.
