Very good range mag - Elite Tactical Systems Glock 19 10-Round 9mm Magazine, Translucent

I have purchased 5 of the Elite Tactical Systems magazines for use in 2 of my Glock 19's. So far I have shot about 800 rounds through them and have been impressed with their feeding, having no malfunctions. The only problem that I have encountered is that a couple of the mags won't drop free when fully loaded to full capacity. I experienced this with both of my Glocks so the problem is not with the mag well of the pistols.
I really like being able to see the rounds in the magazine and the price is well below a factory Glock mag. I have had no problem loading the magazines to capacity, but I do use a couple of different mag loaders due to the volume of ammo I shoot. Loading the new mags by hand I found that the last round is a little difficult to get in, but it can be done.
I would have given these a five star rating if the magazines would drop free one hundred percent of the time, and I recommend them for range use only for that reason.
I will note that one of my Glocks is highly modified and is picky about magazines. No feeding problems were encountered using these mags.
