10mm is a phenomenal cartridge. It's the 357 Magnum of the semi-auto world. It's the literal do-all. You can hunt with it (I've seen guys take 250-300 lb hog with a 10mm) and use it for personal defense either in the woods or on the street. The thing to look out for is the fact that factory loads aren't exactly up to snuff. A lot of companies don't take advantage of the pressures that 10mm is designed to achieve, and you basically end up getting what turns out to be a 40 S&W +P. You should be seeing at least a 2-300 fps increase from 40 to 10mm with the same bullets. Energy levels should be right there with hardcore 357 loads starting at about 650 ft-lbs and going up from there. Any lower than that, and you aren't taking advantage of the cartridge. If you need more punch than a fully fledged 10mm, go get yourself a 44 Magnum. Both 357 Magnum and 10mm have the unfortunate tendency to be loaded much lighter than their cartridges have the potential for. Underwood and Buffalo Bore are some of the only companies that really put out ammo in 10mm that realizes the potential of the cartridge.
As far as recoil, yes it is going to be more stout than you're probably used to if you've been shooting 9, 40, and 45. Personally, I've had my idea of what recoil is readjusted by some very large rifle calibers, and my own Smith & Wesson 460 XVR revolver, which chucks a 360 grain 45 caliber bullet at 1900 fps, which I confirmed over a chrono. Recoil is relative. If you can handle it, you'll be fine. It's probably not going to hurt you unless you're limp-wristing a 9 or 40. What'll help is getting yourself a nice heavy gun like a 1911, which will help absorb a lot of recoil.
If you're insistent on a Glock, I recommend going to a range where you can rent one, or borrow one from someone. First thing you do is put one round in the magazine. Fire that one, then make sure the trigger clicks once that round has been fired. If it doesn't seem like the trigger reset, that means you actually pulled the trigger twice, and would have fired the second round into the roof. You may laugh, but I see this this more often than I should with heavy calibers and people who aren't used to recoil. This is especially true in new shooters. And a if you think a nice heavy trigger pull will save you, you're mistaken The S&W 500 revolver has a 12-16 lb trigger pull in DA, and a woman was recently killed when the recoil caused her to double tap while at the same time the muzzle rise was so great that she shot herself in the head.
And this is a similar event:
