I have the Glock 32 I agree the ammo is to exspencive.but I thing if you look at the balistics it has alot more to offer then the 9mm the 10mm or the 40 or 45. If I were in law inforcement the 357 sig would be my choice. And my Glock 32 is dead on I like to try the M&P in 357 sig my M&P 9C is also dead on just my thoughts.
