I'd like to hear anyones thoughts on this. Since the TSG-22 is blowback operated, and since it pretty much requires hi velocity 40grain ammo to operate I'm thinking lightening the slide will help in function on a lower velocity round. My thought is to open up the top of the slide like a Glock 34. My father in law is a master fabricator and has the appropriate tools so having him do the modification is no problem. Is anyone else following my train of thought on this? Am I way off base here?
