Hello ladies and gents. I just scooped up a full size PX4 storm in 9mm and was curious to see what informed minds had to say about resources/advice on this particular pistol. Im looking for a holster that will carry comfortably and be able to accomodate a laser or flashlight, and in the future a sight/targeting upgrade depending on how the factories perform. Anything to look out for over its life? Known failures? Mods that make it run better?
