I saw an add for some 50 round USA mags that were advertised as Colt 9mm 50 rnd mags made by USA mags. I asked the seller if the mags had the bolt hold open feature and the reply was yes. I then checked around and can't find any "USA magazines" 9mm Colt 50 rounders that had the bolt holt open feature, they were just real long Uzi like mags. Are these for real or is the person pulling my leg?

dont know if the have the bolt hold open but the general rule of thumb is to run far away from USA brand mags unless there the ar15/ak hybrids made from welding a ar15 mag top to a ak mag body.

Don't buy ANYTHING made by USA.

Thanks Guys!
