Yeah but I am pretty hard set against altering arsenal condition. TBH the gun does not need a slide release and rigging one in just is meh.
It probably would work for a PPK type as well assuming they use the same catch mechanism.
Actually you can actuate it by hand, it is just awkward as hell, the bar is exposed on the outside of the gun and can be raised by hand if you are dexterous enough.
...but their exists also in the human heart a depraved taste for equality, which impels the weak to attempt to lower the powerful to their own level, and reduces men to prefer equality in slavery to inequality with freedom.
