Glock 21

[Seabeeken]

Can a Glock 21 45 acp be converted to 10mm?
Is a simple slide, barrel, and magazine change all that is necessary?

AFAIK yes. They have the same frame.

Mostly. Some people have had to change the ejector also but that's a small thing and may not be needed in your case.

Thanks for the info!! I was sure someone here would know

Did some checking. A G20 slide will fit it but there are none to be found for a Gen 4. Plenty of Gen 3 slides but no Gen 4.

You don't have to buy the whole slide. They make conversion barrels that will fit your slide. I haven't researched this much, but you MIGHT need a different recoil spring too.

Glockstore. Storm Lake $160. Lone Wolf probably cheaper...

Thanks, I'll look into that. The spring and an extractor change are also required for the conversion. Still not sure about the ejector.

Then, if you're like me, you start to wonder if 10mm is the way to go .... or do you start looking at .45 Super.

Choices choices.
