Won't it? The gun is going to be hanging between your legs where a real man keeps his natural equipment.. (quit laughing RIKA)... that means that your sweat which is very high in salt content is going to leech in everywhere.
Hmm, as a general rule of thumb, when I see a gun at a gun show that is poorly maintained on the exterior, I assume (usually rightly so) that it has also been poorly maintained on the interior. If you are going to take the time to maintain the interior of the gun, why the heck would you scrimp on the extra couple of minutes necessary to care for the exterior as well?
Sounds like you are being penny wise and dollar foolish with your time to me.
I could never have any respect for a man who let his personal gun get all nasty, either on the inside or the outside. But then people who don't actually use their personal equipment but just brag about it are prone to be careless and sloppy, aren't they?
