Glock 17 shoots full auto
 

Hi friends. I have Army Armament Glock 17. I have used it for 2 years periodically changing some parts. It is a clone of TM G 17. Last time it began shoot full auto, and I can't understand why. I have some thoughts about what can be the problem, but I would be happy if some experienced members could give me a piece of advice. Thanks!

It could be the hammer sear is worn and is causing the hammer to slip continously.

Thanks friend. I spent hours examining it and also decided that with great possibility the problem is with hammer sear. I am also suspicious about the trigger lever.
