Reasons to get at least one twenty round magazine.
1. Gives you that nostalgic look.
2. Lots of the ammo you buy comes in 20 round boxes, one box=one mag.
3. In a close quarters combat situation, more compact 20 round mag gives a little more clearance.
4. The quality of most original USGI 20 Round mags is hard to beat. Of Course, USGI 30 Rounders are also built to last.
5. Can easily be reloaded in 1/3 less time than a 30 round mag. On the flip side, it Will be Empty in 1/3 less time.
6. Better get two, 'cause of the flip side of reason #5.
7. There will come a time when there are no people left willing to part with their remaining original USGI 20 rounders. Get 'em while you can.
8. Does that little stamp mean "Universal Industries", "Colt Hartford", Or "Indiana University"? You Decide!
