I thought Glock, too. I used to own a Glock but I had to sell it because it kept crawling out the front door and firing rounds off at random.
None of mine do that. You should call the factory.
My sister carries a Glock and all you have to do is breathe on it to make it go off. A neighbor of ours and retired police officer shot his television with his. He said all he did was pick it up. My husband traded for one and was afraid to sell it so he eventually sold it to a police officer as a personal gun, very cheap. I’m afraid of them.
