A friend of mine has one in 9mm and I think the whole concept is great.... He takes his in his backpack when we go ridding out in the desert!... I've shot it a few times and and wasn't to impressed at first ( it felt kinda cheap and rough around the edges) but when it came to shooting it I gotta say I did like it... Specially when we used The rounder (factory) Glock mag.
P.s. Don't buy pro mag mags for it! They do not work at all
A man who is good enough to shed his blood for the country is good enough to be given a square deal afterwards.
