Ran about 100 rounds through my TM deagle hardkick on propane, no issues. But on my Ksc glock18 ran fire on semi, but the first mag I ran through on auto the slider cracked and came off and shot the spring half way across the room, albeit I have to admit I think the shop keeper sold me a bum gun, even though he claimed it was new in box, but it looked used and was probly a return. But over all Ive never had an issues with running any TMs on green gas, but well most of the TMs Ive used are fairly new and well that slider on a DE is fairly thick. Never had an issue with a KJW though.
