Very nice! I have been thinking of getting one as a project gun. The magazines that you have are 9 rounders right? I think the 8 round versions have a flat floor plate and would fit into your mag pouches.
I know that the standard Glock mag base will limit you to 8 rounds and will fit the closeable pouches, but I might just switch to the exposed mag pouch or get some custom leather puches. Still deciding.
