They shoot great! It may or may not break?, but it will definitly show wear, (tight fitted toggle train almost always shows some scuffing on the top of the links) BUT, only load the mag. to 5 rounds, and you will have a much more pleasurable outting...as the mag. springs are ridiculously strong!! Your thumb will wear out long before the gun! best to you, til..lat'r...GT
BTW, If I have a really nice gun to shoot, and I'm really concerned about rash...I never have any problem when shooting it, It's only when I drop it or bang it on the car door frame that the "feeling bad" time begins!
