A # 1 Product

by

Retired with a Gen 3 Model 32 .357 sig. service weapon. It killed on both ends, ordered the Double Diamond 9mm conversion barrel and dropped it down to a 9mm.

Gun works flawlessly and the teeth have been pulled from that old .357 sig monster not to mention the 9mm ammo is dirt cheap.

Great perfect drop in fit.
