Frequently Asked Questions

Can you put a Glock 19 barrel in a Glock 23?

Yes, a stock Glock 19 barrel can be installed into a Glock 23 slide. While this may result in a loose fit, the configuration was successfully tested firing 15 rounds of 9mm ammunition without malfunctions.

What are the main differences between a Glock 23 and Glock 19?

Externally, the Glock 23 (.40 S&W) and Glock 19 (9mm) share identical dimensions and frames. The primary internal difference lies in the ejector: the Glock 23 has a straight ejector for .40 S&W, while the Glock 19 uses a curved ejector for 9mm.

Are there aftermarket barrels for Glock caliber conversions?

Yes, aftermarket conversion barrels exist that are designed to fit .40 caliber Glock slides but feature a 9mm bore. These are often designed for a tighter fit compared to using a stock 9mm barrel in a .40 slide.

What happens if you put a 9mm barrel in a .40 Glock slide?

Installing a stock 9mm barrel into a .40 caliber Glock slide can create a noticeable gap or 'slop' due to differing tolerances. However, in testing, this configuration still functioned reliably, firing 15 rounds without issues.
