I have tried to google this but apparently I'm using the wrong words because I can't find what I'm looking for. My Grandson bought one of these for his glock and I really don't understand what it is supposed to be doing. So...........
What is the purpose of the "gas sealing" chamber/barrel?
Because of the "step" in the chamber, how much does this effect case life?
As with nearly EVERYTHING glock, I am not especially impressed, particularly given the price.
