Glock 32

As is typical of pistols chambered in .357 SIG, each of the standard Glock models (31, 32, and 33) may be easily converted to the corresponding .40 S&W chambering (Glock 22, 23, and 27, respectively) simply by replacing the barrel. No other parts need to be replaced, as the .357 SIG magazines will feed the .40 S&W round.
