When I owned any, my favorite striker pistol would have been the Canik TP9-Elite SF. That pistol had the very best trigger I could find in a striker, and equal to many pistols' single action pulls when using in defensive shooting senarios (practice, IDPA shoots, things like that). Ergonomics were great for me, and flawless reliability.
The only problem was that it would NOT shoot cast boolits with any repeatability. Tumbling, spinning, low accuracy, you name it....that is how cast shot through this pistol. And jacketed, right back to stunning performance.
After using my rules for keeping a gun, I decided to pass this one along, and return (eventually) to the B6 series. These shot EVERYTHING I could put through them, and not complain or show much deference to bullet type.
