Air-soft Glock

I Googled "Airsoft Glock", and this was the first result...

Here's another

But part of the reason they may be more difficult is due to licensing restrictions. Apparently, Glock doesn't like other companies making clones of their products...

I won an HFC 185 Glock copy years ago. It was pretty close but a bit tight is a regular Glock holster.

I loaded it to my then minor BIL so he could practice mag changes for IDPA matches on the weekend.

Glock made a big fuss regarding airsoft replicas of their pistols and they successfully got them pulled off the market years ago.

Recently Stark Arms started making replicas again, and they're pretty darned good. If you use Airsoft for Force on Force, this is a nice addition.
