CDNN has some asian military super extended cap. glock mags. they had them in 9,40/357, .45. so i ordered up 3 for the .45 and bent the feed lips in to match my factory g29, and g20 mags. they feed flawlessly. i took all of them out to the woods after work and filled them to capacity which by the way is 31 rounds. fed fired and ejected 100% proper with 10mm rounds, when i switched to 9x25 they would only feed right if i loaded 25 or less. but i am not hosing away with no 9x25's anyway. here it is 9x25 setup below the mags were only 18 bux, and like i said just three or so light but firm hammer stikes on each side is enough to hold the 10mm in there just like the factory mags. get them while you can!!!! her it is, it is a little Wanna kill these ads? We can help!
