The "mm" Glocks are designed well for the caliber it holds, whereas the "caliber" Glocks are byproducts and tend to have a few more problems (although I have never seem a problem with any of them in many years)
The 9mm Glocks are legendary for being tough and long lived.
The 10mm Glocks were specifically designed for the 10mm and later reamed out for the .45.
In other words, you are very safe with a 10mm Glock. The chamber is as well supported as a 9mm Glock and there are very few problems with either one. The barrel and chamber are extremely thick and tough. There is a lot of steel and support there, unlike the .40 and .45 caliber Glocks which are reamed out for the larger diameter.
10mm brass is also tougher than any other on the market, and also, it takes a lot of "juice" (powder and energy/velocity) to load 10mm to it's max pressure potential. It is very rare, even reloading, that you will ever encounter a 10mm load that is loaded to max pressure. No one loads 10mm as hot as it can really go, not factory ammo makers, and not most reloaders. It can go REALLY hot before it exceeds it's limits. I don't think you would ever have a problem with a 10mm Glock in that regard.
