I don't have experience with that particular model or caliber, but I can tell you that glocks are tough, reliable guns.
The cons are the grip angle is different than most other pistols (some can get used to it, some can't) and the only external safety is on the trigger.
Love my Glocks. The closest thing I have to what you're looking at is a Glock 30 (subcompact .45). It's very accurate for a small gun.
Rent one and shoot it if you can. If you can't find a rental in 10mm, shoot either the full-size .45 or .40. The .45 also has a SF version, so that would give you the closest hand fit to the 10mm, even though the recoil will be different.
Some people are indeed bothered by the grip angle. Some people actually prefer the Glock's grip angle over other pistols' grip angles. Personally, until I read someone's complaint about the grip angle, I hadn't even realized they were different.
As for the lack of an external safety, I personally consider that a plus, rather than a minus. That's a personal choice, of course; everyone should do whatever they find comforting. I consider my holster to be the external safety. That, and my brain.

I dont know about the 20 but i own a 23 and, i love it. This is my second firearm ever so the grip angle is not a problem for me. I dont have any negatives but if i had to pick one it would be the safety factor, or the lack thereof.
thanks for the replies i really appreciate it and ive been to the gunshop a million times and i really like the grips for the glocks and i think id prefer the safety be my finger in a time of extreme pressure suck to have the safe on
I carry a 21SF at work. I really like the SF smaller grip; it's more contoured than the regular 20 or 21, which feel like a big brick in my hand. I wear gloves at work a lot and the smaller diameter grip helps keep a good hold on it.
The Glock 20 is the full size 10mm, built on the same frame as the .45 ACP Glock 21. If you simply like the size of the gun, you might consider the 21 or 21SF since ammo will be more readily available and perhaps slightly more affordable.
The 10mm Glock 20 is also an excellent choice, and IMHO one of the best 10mm pistols on the market. For simplified explanation, imagine 10mm as ".40 caliber magnum" and you'll be in the ballpark.
Along with others here, my preference is towards the slightly reduced SF frame over the standard frame.
Enjoy whichever model you decide upon, and let us know what you think.
