I was looking into a .22 caliber pistol for cheap shooting and a nice way to introduce my fiancé into the handgun world. I was looking at the M&P22 because I'm buying myself a 10mm glock and I want have a m&p also to see which I like the best for future purchases after my colt 1911. In my reviews and research I saw that they were single action whereas the other m&p models were double action. Are the .22s truly single action or am I missing something? Any other input of nice .22lr pistols would be helpful.
