I just put an extended magazine on mine from Choate. But I already don’t like it. It really changed the balance. I think I am going back to standard. It did change where flashlight mounted and that was a plus as it got rid of some of the weird shadowing. By same token I have not pushed hard on it yet? So I might be premature on my assessment? Hard to see an application outside of competition arena that a side card does not negate the advantages of the extension?
