I've actually observed split Glock mags at the back of the feed lips. It was my buddy's old .40, and the older mags apparrently(?) did not have the same steel reinforcing at the top of the magazines. He sent them in to Glock, and got back new mags with no problems. At the time (having little experience with "Tupperware" guns), I chided him, made fun of his cheap plastic pistols, and kept right on shooting my steel Gold Cup. And, of course, down the road, when my Gold Cup developed some problem or another, he laughed; paybacks are sheer
hell, let me tell you. (
)
But the point is, I've never seen my buddy's problem duplicated. He had a couple of lemons. Completely anecdotal, statistically unimportant lemons. When they were replaced, the problem was fixed, and he's never had another lick of problems with his Glock.
I don't own one, and don't want one, but that's for personal reasons. Not because the material is too soft (It only has to be harder than my hands), or fragile (I can't break them any easier than I can my Government Model), nor because the magazines are more breakable.
The vibration statement is just bizare. One of the things about polymer frames that has most impressed me has been the reduction in felt recoil for a given weight pistol. Obviously a polymer 9mm of a given size will weigh less than a steel 9mm of the same size-- compare a G17 to a Browning High Power-- but ounce for ounce, the polymer transmits less shock, in my opinion. I was shocked the first time that I shot a Kel Tec 9mm next to a .380 AMT Backup, as the Backup seemed to kick more, though it was heavier and fired a more anemic cartridge. Some of this had to do with the increased width of the beckstrap of the gripping area, but I fully believe that the composition of the frame had something to do with it.
But we appreciate the warnings of the possible dangers to our firearms. It had never occured to some of us to worry about these things before.
