Airsplat has some, Glock is suing them though. Ol Gaston hates that anyone makes a dime without him getting anything. Actually, I dont think he likes it even if he does get paid. He not only doesnt want the company logo on it, but he doesnt like it looking at all like his guns or even fitting in the same holsters. 'turd.
Check Airsplat's website, last I looked they were back ordered 6 weeks and they had the suit filed last month so it may be a little risky. But having an airsoft training gun is an awesome tool.
