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.

Installed SKU: 1012-STS-A27 9mm conversion barrel on my .40 S&W caliber Glock 22. Almost 500 rounds thru it without a single malfunction. Surprising the 9mm shot to the same point of aim as the .40 caliber. Average group at 7 yards is 3/4 inch.
