If you've ever shot a Walther PPKS, you would not want to have the thumping sharp slide rail slicing into the web of your hand 8 times per second.
I did something like that but only one pass, that you very much. With a Walther PP that I had as a kid. I wanted to see if I could drop the hammer manually and move my thumb out of the way before the slide fully recoiled. I lost that little contest. Kids and guns. Ain't it amazin'. I've decided there are sound reasons for age limits on buying guns.
