I think it was the cop in the video above who mentioned that Glock mags function very reliably, but their weakness is a tendency to blow out the bottom plate and throw cartridges everywhere. He also gave a lot of focus to changing out magazine springs after a lot of use owing to the tendency of springs to wear out after enough load-unload cycles. More of an issue for full-auto though, where a very fast spring rise is crucial, usually not so critical for semi-auto. And on the subject of springs, he mentioned swapping out mainsprings after something like 7,000 to 9,000 shots if memory serves, with blow-back actions, as springs weaken with use. As for Glog magazine base plates, I suspect Magpul or SGM or other Glock-style magazines would suffer a similar fragility problem.
Of course an advantage we Canadians have comes from rivets; with our magazines pinned at 10, who cares if the bottom plate blows up? Just duct tape over the bottom to keep the spring end from catching on anything and keep on shooting. Who knew there was an advantage to rivets?!
