I have the M&P .22 and It occasionally has a FTF. I would say, if I'm shooting some bulk ammo, one or two every other magazine or so. Usually it's the second or third round of the magazine. I have three and it doesn't matter which one it is. If it's going to happen, it'll happen. A quick rack and you're good to go. Obviously it doesn't do it on the higher end ammo like CCI.

I will say that I looked at the 22A when researching a plinking pistol and decided against it (and many others) because apparently it's tough to do a semi-auto .22 well because you have to balance the slide weight, recoil spring and feed ramp just right to have it be reliable. People also make comments about a lot of semi-auto rifles with .22 ammo.

My shield is a 9mm so I don't have a magazine problem, but my friend bought a Kahr CW40 and the mag drops ever so many shots, but only with one of the magazines. <shrug> Not sure why. He hasn't decided if he's going to fight for it or not.
