Bersa .380, unreliable, hard recoil. Soured me on autos so bad I carried wheel guns for two years.
Taurus Ultralite 2" 38 Special, yes the sight of it sent a robber fleeing down the alley but recoil was vicious, trigger was awful, and the finish was dreadful.
Walther P22, what everyone else has said, real picky on ammo, not very accurate. Traded it for...
...a Kimber .22 1911. Not picky on ammo but even less accurate than the P22. Traded it for...
...a stainless steel Ruger M77 chambered in .270 Winchester. Weighed as much as a fence post and shot 5" at 100 yards with the very best ammo.
Ruger P89, weighed as much as a brick, and about as concealable as one too.
Titan FIE .25 ACP, no explanation needed.
Beretta CX4 in 9x19, rifle verision of a Beretta 92, less accurate than a Beretta 92.
Kel-Tec PF9, worst recoil I have ever experienced outside of a scandium J-frame 357.
Taurus Tracker .22 5", should have learned from my previous Taurus revolver experience
Tristar 20 ga autoloader, perfect finish, but couldn't break many clays, didn't point quite right.
