10-4nwhen I went to the Academy in the 70's it was on Confederate Ave. and we shot SW Model 10 at the qualification range, carried a 38 till the SW Model 27, 357 mag came out, then went Dirty Harry with a Model 29, 4", that puppy would bust a mag wheel when shooting at tires to stop em, like they should nowadays, might save a few lives.Most cops carried revolvers for decades as well as many civilians. Many still do. The 43 still holds one more round than most revolvers and 2 more than many of the 5 shots.
