Glock 17 Plastic training barrel

I can’t find any Glock 17 plastic training barrel in stock anywhere, does anybody know where to find one? I need a way to make my pistol inert, but functional for dry fire and scenario training.

All I see out there is this. Pretty pricey. https://www.morgantiming.com/store/c2/Dry_Fire_Training_Barrels.html

Looks like Blade Tech has discontinued theirs. Which is what I have.

I have no experience or connection to these barrels, but they seem economical. https://www.ebay.com/itm/PISTOL-TRAINING-BARREL-INSERT/273598303915?hash=item3fb3baceab:m:mUq_Wv3TCgiyBAcM_DL7a5g

You should be able to find some of the Blade Tech ones around still, maybe check ebay? The above link also has some that are kinda similar.
