I remember reading in mazazine a couple years back reading a magazine about the Glock 30 and 29. Seems if I remember correctly that the Glock 30 used an extender on the magazine to bring it up to 10 rounds. It stated that using this extender on the 29 mags would constitute the contruction of a "high capacity magazine" and thus would be illegal. Now that the bans over it doesn't matter. An 11 round 10mm in that size sure does seem well interesting. Do they make factory extenders for the 29 to be an 11 rounder?
