I could see the Charter Arms Pit Bull being attractive for use as a BUG to a semi-auto in .40 S&W, particularly amongst cops using department-supplied ammunition. The problem is that the .40 S&W Pit Bull is substantially larger than a S&W J-Frame which itself is considered by many to be the upper limit of acceptable size for a BUG.
