I've been very interested in a PCC since the bills for my second child's birth have slowly abated over the last few months and I've been able to budget for a new gun purchase. As I look at the options on the market I notice there aren't many that seem to offer an ambidextrous magazine release, without leaving the AR9 platform, especially if I want to use Glock magazines (which I would prefer). However, as I understand it the Colt-style magazine well conversions may be compatible with ambidextrous magazine releases, and that would (with a buffer and spring swap I imagine) jibe well with my existing Aero pistol lower build. This may even make the build a little cheaper to offset the cost of the Colt SMG magazines if I were to go that route. Can the southpaws in the room point me in the direction they went? I can run guns without ambi releases, but it's just so much more fun with a fast magazine change ya know?
