Very hard to load - Magpul Industries PMAG 10 GL9, Glock 17/19 10-Round 9mm Magazine

I thought I would give these magazines a try for the price. I have some magpul magazines for my ar15 and I have no issues with them but these for my Gock 19 gen 5 are horrible. They are so hard to load after putting four bullets into the the magazine I have to use my magazine loader to put the rest in or I risk breaking my thumbs. These do not have a ss liner inside like the original Glock mags so there is more friction loading the bullets making it way more difficult. Save your money and buy some original glock mags.
