After my usual trip to the range today,and while taking the slide off my p3at i noticed the pin is somewhat loose and no longer makes that snap noise while putting it in or taking it out to remove the slide..is there a way to tighten it up, as i fear if i dont, it may start walking out while shooting the gun? the gun has about 100 rounds through it and shoots well...its in my back pocket in a leather TALON GROUP holster, 24-7....
