I have a Springfield EMP in 9mm. It is a very nice little carry weapon. The only problem is the bottom corner of the mainspring housing is checkered and after a few rounds, rides very uncomfortably in my hand. Too the point that it is very annoying. I would hate to shoot more than a few mags through it at a time. Does anyone know if any company makes a new mainspring housing that is smooth or fits better? One plus would be to get rid of the ILS. Maybe I should just sell it and get a colt defender. Any help is appreciated. I have tried a google search and have checked around on a few other forums but have not really turned up anything helpful.
