I was debating have the slide milled on my g26 gen4. I am going to be doing this in conjunction with an LW external ported barrel. I know when you lighten the slide it affects your cycle rate which can lead to reliable issues and the gun being battered. I have found a lot of aftermarket springs for the larger glocks but nothing for the little g26. Can you guys suggest where I could get different springs and/or what kind of springs I would want to be aiming for?
