Not a purchase, but rather a trade. The friend who traded me the first pistol he ever purchased, a Sig SP2022, regretted it and wanted it back. So I traded it back to him for a Springfield XD-s 4" Bi-tone. It's a nice gun except for the trigger.
The trigger on the XD-s is over 8lbs, hard mush to the break, reset farther out than it needs to be. A $70 Powder River Precision spring and sear kit would bring the trigger down to 5 - 5.5 lbs, shorten the reset, but still would have a soft mush before the break. I don't think I want to put $70 and time into the XD-s. It will end up being trading fodder.
