Promag 43x " 1 "round i repeat 1 round mag follower n spring are horrible have took apart still nada - ProMag Steel Glock 48/43X 9mm 28-Round Pistol Magazine

Have sanded cleaned greased reassembled tried everything do not purchase this magazine unless you want to be mad because you wasted money Glad I did not also purchase a 15-round pro mag The ETS plastic magazines run flawlessly I would definitely go with that route rather than throw money away on a reputable brand name that sells garbage they should recall all of their 43X28 round magazines
