I have a .40c that I am thinking about putting on a full size slide. I dont care for short barrels on compacts, but with my build a full size grip is a bit much to conceal. Also the sight radius, muzzle velocity etc is attractive. I see the new PC slide kits are about to be out and I am looking to go that route. I own a PC Sheild and love it. I have full Apex on my .40c short of a barrel because of my current temptations. Anyone have any experience or insight into this? I do not know much about the ATEI hybrid and I am not too crazy about having a non stock recoil spring setup as long as they are readily available.
