Frequently Asked Questions

Can I put a 9mm barrel in a .40 S&W Glock slide?

You cannot use a standard 9mm barrel in a .40 S&W Glock slide because the outer diameter is too small, leading to poor lock-up and accuracy issues. You need a specifically engineered 9mm conversion barrel designed with a thicker wall to match the .40 slide dimensions.

What are the benefits of using a 9mm conversion barrel on a .40 Glock?

Using a 9mm conversion barrel allows you to shoot cheaper 9mm ammunition, significantly reduces felt recoil for faster follow-up shots, and often increases magazine capacity compared to the original .40 S&W caliber.

What makes a 9mm conversion barrel different from a standard 9mm barrel?

Conversion barrels are built with a thicker outer diameter to properly fit and lock up within a .40 caliber Glock slide. Standard 9mm barrels are too thin and will not function reliably or accurately in a .40 slide.
