Interesting thread here. I was an old revolver guy, but sold everything off years ago for personal reasons. Just started back in a couple years ago, not much money after a bad divorce and thought I needed SOMETHING around the house, and the .40 caliber had been interesting me for some time. Went and picked up a Hi Point JCP .40. Yep, has a bit of a bad reputation, but I know some will say I must have gotten one of the good ones. Accurate as hell with the fixed barrel. Bought some more magazines from the factory and it turned into a jammin machine. BUT looked close at them, and man... dont know who makes their mags but they need to be beat. I cleaned them up, powdercoated them so they had a decent finish, dremeled the stamping flash off the body and set the mag ears to the same specs as the one good mag and haven't had ONE malfunction in over 1k rounds since.
Bought an abused C9 compensated model off a guy, called HP and had them send me (free) a new firing pin and spring assemble, recoil spring, extractor and spring. Not one problem with it, have around 1500 rounds through it now, accurate but noisy with the comp on it.
SW40VE was my third purchase. Smoothed out the sear assembly to get rid of the gritty trigger pull. Works fine and accurate as long as I stay with heavy grain bullets. It likes the 180 gr in FMJ and JHP's as well. Shoot a 155 gr and it will jam every round.
Picked up a Phoenix Arms HP22 for the kids and wife to plink with. Not a bit of problem unless you want to count misfires where the cheap ammo just doesn't fire. No problems, must have gotten a good one but I don't buy the super-cheap bulk packs unless I want to spend a little extra time clearing out the occasional stovepipes.
Worst ever firearm was my issue M16. Would either stovepipe or FTE like crazy.
Picking up an Armscor M1600 on the first just because it's so damned ugly...
