Do you think there is any way to fix the issue of not being able to hold the mag during firing? Would there be a way to shim the mags or maybe the inside of the lower reciever so that they wouldn't misfeed? Thanks.
ETD...ARGGGGG, just re-read your post and see that it's the slide guide on the mag and not a feeding issue. Still, is there a way to hold the mag to stop this from happening?
