Holster for ruger security 9

[Huntnfish89]

Just looking at some options for holsters for a Ruger security 9. I picked one up recently and was thinking about trying to something that works as a modular system that I could switch from hip to drop leg, or pack belt. I know it's not the ideal woods gun per se but still.

I was looking at the alien gear shape shift system, but it seems that they dont make one for this particular firearm. Maybe the one for a glock 19 would work as they seem to be pretty similar in size and shape?
