This is the factory Glock .40 barrel that comes stock in the Glock model 22. It can also be used to convert the 22C to shoot as a non-compensated. Converting the 31 or 31C to shoot .40 s&w is also possible. Using it to convert the 17 to shoot .40 s&w is not safe as it will not fit into the slide properly. Calibers can only be converted down, not up. This barrel will not work extended in the 23 or 32 due to the difference in the locking blocks.
Caliber: .40 s&w
Height: 1.26 inches
Length: 4.49 inches
Rifling: right hand, hexagonal
Length of Twist: 9.84 inches
Travels at: ~ 985 feet per second
Using reloaded or lead ammunition in Glock barrels is NOT recommended!
||WOW! Great Factory Replacement Barrel
|I have thought about getting a .40 barrel for my 2nd Gen G31 in 357 Sig for years. I was always concerned that it would not shoot to the same point of aim and I would have to get adjustable sights. I finally broke down a purchased one a week or so ago from Glockmeister. It is a lovely thing to look at, but how will it shoot. I just got back from a range session this morning and WOW! I first dropped it into my 2nd G22 and it shot exactly to the point of aim as the original factory barrel. Ah, but thats in another .40, what about a caliber change. So, next I dropped it into my G31 with .40 magazines. Well, it shot just a tad - less than 1/2 inch - high at 30 feet, but since the .357 Sig has always shot a hair low, a half inch up makes about perfect. Now I can shoot the .40 ammo for about 1/2 the cost of .357 Sig. Love it!|
