There are plenty of .22lr semi auto pistols on the market. Having owned several brands and models, I've found that many of them have the barrel attached/mounted to the frame itself, like the Ruger SR22(which is removable with tools). I assume this is to assist with feeding and accuracy. Are there any .22 pistols where the barrel is not attached to the frame(Sig Sauer short recoil system style, like glocks, ect)? Not counting the Buck Marks, Ruger Mark Series, ect.
