Looking into possibly getting an auto .22lr handgun. Choices I'm looking into are the Walther P22, the Sig Mosquito, and the Ruger SR-22. Few people I've talked to highly recommend the SR-22, and just wanted to hear some other opinions (Experience based). Only bad things I've heard about the others are they are finicky with certain ammo. Is this the case across the board? Or just specific to the Mosquito and P22?
