I used to put a spare magazine for my Warthog in my jacket pocket or trousers (if there was room). I could not see putting a magazine carrier on my belt and then carrying concealed...kinda defeats the whole purpose. Of course, carrying extra ammo in ones pockets is not a very safe nor sanitary (for the ammo) idea either.
So, I thought occured to me today (an almost annual event!)
In my "junk drawer" was a small pouch that a Gerber multi-tool had come in. The tool resides in my motorcycle "on the road" repair kit, so why not use the pouch for the magazine?
The fit was nice and snug and the end flap completely concealed the ammo. The Gerber Logo on the outside satisfys casual curiosity and I feel a whole lot better having it secure and readily available.
