No, but I had one that was often damned by faint praise.
Ruger P90. All Ruger P-series are often referred to as "good solid guns with poor triggers." Mine had the heavy long gritty pull, but was VERY accurate for a combat gun. Focusing on the trigger pull issue, I just bought a 1911 this year, and found that it is not in the same league as that old Ruger from a reliability standpoint.
O.P. - Regarding S&W ruining the PPK, that is one of those things that gets repeated very often, and is seldom (if ever) substantiated. To the contrary, everything I've read from actual owners suggests that S&W improved the PPK, as slide bite is no longer a problem and feeding reliability, esp. with hollow points, is better.
The only point I can make against the PPK is that they are expensive. One could argue that the Bersa Thunder 380s shoot at least equally well for half the price. But there seems to be a niche market for well-made 380s. Walther PPK, Beretta 84 and 85, Sig Sauer P230 and 232. Only now are simpler, cheaper-to-manufacture 380s storming the market.
