I am buying a 9mm AR very shortly and have some questions about magazines. I really performance of the 9mm out of a carbine. They are light, ammo is cheap and 147grn JHPs have some serious snort out of a carbine. It was my understanding that Colts, or similar models, use a propritary Colt magazine which is simliar to an Uzi mag, and that it was possible to modify an Uzi magazine to make it compatible. I belive the Colt 32 round magazines sell for around 50.00,
which is more than I am willing to pay as I compulsively buy magazines. Uzi magazines seem to be very reasonable, but how involved is the modification process and does it make the magazine less reliable after being altered? It seems to me, that the Olympic which takes the 33 round
Glock magazines may be an even better idea. The mags are cheap, widely availble and have excellent reliability. I have "fighting" rifles, so for this role buying an Olympic doesn't confront me at all, especially since it will be considerable cheaper and have a lifetime warranty. I have a line on a Colt a friend is selling, but I am unsure about the magazine situation. I would rather not have another Mini 14 GB situation where the only way I can exploit the reliability potential of the
weapon is to buy factory magazines at a premium price. If the modification to Uzi magazines isn't extensive, complex or compromising then that is probabaly an solution. But as I see it right now, the Olympic which takes Glock magazines is the best choice. What do you think? Any insight, suggestions or experience?
