S&W 76 / MK 760 Custom Barrels

The top barrel is an 8" stainless in .30 Luger. The bottom barrel is a 5" in 9mm Luger. While individual gun and ammunition combinations may work with barrels shorter than 5", our testing has shown that a 5" barrel will function in every S&W 76 and MK 760 in which it was installed. Therefore, we recommend 5" as the minimum practical length. If you want a shorter barrel, we will make it but will not guarantee that it will function in your gun.

We WILL NOT make barrels for the 76 / 760 in any chambering packing more punch than the 9 x 19 Luger or .30 Luger. Please see the FAQ section for a more thorough explaination of why.
