Exactly original, GI mags = Checkmate Industries. Get them with the XP springs, which are Wolff Extra Power equivalent. You must ask for the XP's. Not to be dismissed; only a 2.40 option instead of seven bucks aftermarket.
Do NOT fail to order the XP springs.
These GI mags, due to a knowledgeable gunsmith's input, are actually as good or better than original GI's because the release point has been optimized..this makes these excellent for ball, HG 68 SWC's and HP's with a ball like ogive. What makes them better than original GI's is the offering of the XP springs. Not to be missed out on!
