Is it possible to use 9mm on a 40s&w Glock?  What do you need to change it?

You will need a .40 to 9mm conversion barrel (NOT a factory 9mm barrel––this won't work). Look at Lone Wolf for this.

You will need 9mm magazines for the model you are converting (if converting a G22 you need G17 mags, if converting a G23 you need G19 mags or G17 mags, etc.)

You will need to change out the .40 extractor in your slide to a 9mm extractor.

Vini will be along to spell out anything I've forgotten.

Thanks, this reaffirms what I knew.  I was discussing this subject with a friend and wanted to make sure, so I turn to the expertise from you guys.

Cheers

How well do the 40 to 9 conversion barrels work with the larger breech face?
