I always found the Glocks to have a weird, almost twisty characteristic to them when fired. They don't fit my hand nearly as well as the either the single stack 1911 or my para-style, though. And I'm still biased against polymer stocks, but that's an emotional thing rather than practical.
As with most shooting-related problems, the problem is usually the shooter, not the equipment, so I'm willing to take a hit on this one
However, Hydrashoks....eww. Too many stories about clothing clogging them up. A cop buddy from Texas even stopped one with nothing but a leather jacket and a hooded sweatshirt. Granted, it was a 9mm round that hit the zipper and travelled around to his back within the lining of the jacket (post terminal ballistics is a chancy thing with any 9mm). But I'm skeert.

edit: of course, i went looking on the internet for facts to back me up, but i couldn't find any. bah.
Golden Sabers have that nifty scalloped jacket that really tears stuff up. More and more people are moving to them, especially as an alternative for revolver shooters whose guns aren't +P rated
