Nifty. You just put that together for grins and giggles? I might have to buy it off you.
I like a sweat shield that covers the metal as I have acidic sweat and Arizona causes some sweating here and there. The back of the mag holder - is it bare kydex, or could it be lined with some soft leather for fat guts? I carry concealed under a loose t-shirt in summertime. The only one I have is from a company that went under well over ten years ago. Did you know in all that time I didn't have a single photo of it? Just now, shows a LOT of honest wear.
P-10C and magazine for comparison.
That mag holder has been adjusted for the P-09, the Phantom, the P-07, and was originally made for the P-01.
If you can read the stamp, that's Hazel Gun Leather from Colorado. That WAS a while ago!
