[G.Sgt Marty]

My idea is loading ur Mag by hand.....I know it's a pain in ur ass, but if u can't find a speed loader to fit ur Mag Entry, then ur thumb is ur only bet lol.
When I was in the Military, we had to thumb our rounds into our mags, there were no speed loaders for us, but u train urself to be fast at hand loading.

Good luck and Semper Fi!
