I'm actually following in your foot steps and getting a sub compact glock. Model 26 9mm.
Hey, check this outhttp://www.botachtactical.com/vigl9mm33ma.html
These mags have pretty good reviews, check them out. I ordered two already. They are only $12.
Just an FYI, Botach Tactical has terrible customer service. Knowing that going into it, i am not expecting to get my shipment for 3+ weeks, so im okay with that. I've dealt with them before, and they communicate terribly, and probably take too long to get you your stuff.
But for the price, im going to risk it.
