Mikey, glad to know you're an engineer also. I'm an EE doing power and lighting designs for facilities. If I'm in the mid Tenn area , I'll come shoot with you guys. I will be at the Nationals also, along with at least 6 others from the Atlanta area. Mike Benedict a 4 gun Master shoots with us now in Atlanta, he'll be there.
I don't know much about the 210mm mags. (sounds like an IPSC equipment, hee hee). Try it in the box, I'd like to know also if it's legal. I shoot mainly CDP (marksman) .45 ACP Colt Govt. built for street carry. Sometimes I shoot SSP (sharpshooter) with a G19. Hope to see you at the Nationals, I think I'm in squad #11.
