I can name a bunch, but I'll stick to the latest. The Ruger 9MM American. I wanted a "knock around" Nine for hikes and didn't want to abuse my CZ's, I bought the American. Really crappy trigger and I couldn't get a decent group with any ammunition. Sold it at a loss and bought a CZ 09. I have three Colt AR-15's and thought I would get a Mini-14 for something a little different. A friend had just bought one and invited me along for a range shoot. Sadly. the Mini-14 is not in the same league as the Colt's, not even close. Had some failure to feed's, and some stovepipes with Winchester and Remington ball ammunition, accuracy at 100 yards was mediocre, and that's being kind. 8 to 10" patterns are not what I expected. The Polish P-64 in 9MM Makarov looked great. Small size PPK looking pistol with a punch and it was C&R legal so I ordered two. Worse trigger I ever tried, including the Nagant revolver which is saying something. The double action had me squeezing so hard I accidently triggered a second round when it transitioned to single action. I was advised to try Wolff springs, but I know when I won't ever like something. That's the three that I can come up with quickly. I have lot's more.
