Will a Glock 20 fit in a Glock 21 holster?

[Xfire68]

I am shopping for a holster for my Glock 20 and some sites don't list any for the 20 but, they do for the 21. I was/am under the impression that they are the same on the outside?

Also recommendations are welcome. I am looking for a range holster and down the road if we here in IL are lucky enough a IWB holster as well.

Yes, the guns outer dimensions are exactly the same. The difference between them really is barrel diameter and maybe an inner part or 2.

I'll let ya in on a little secret....SOME, not all, will also accept a 29/30 without issue.

^^^correct. One caveat---just make sure you're not getting a G21 holster designed for the 1913 railed version as they generally are not cross-compatible.
