Hey guys, I had a couple of extra clip-on Don Hume leather mag pouches for my S&W single-stack 45acp.
I love these pouches but wanted to get one for my double-stack mag for my P - 09.
I took one of the single stack leather mag pouches soak it in hot water for about 2 minutes, covered my loaded double stack P - 09 mag with a plastic bag and forced it into the leather mag pouch slowly.
It's stretched out nicely. Using a double 00 BB . I pressure formed another indent in the leather that helps hold the mag. Works great.
Now I have the mag holder I like for a double-stack MAG👍.
EDIT : now that I think about it that may be a great advantage to having single stack leather because at some point you can stretch it out for double stack if need be.
