I used to have a G20 and liked it. I had a few reasons for getting rid of it, sometimes I regret doing so, I still have some cases left that I keep in case I go back.
The chamber of the G20 does not support the case of the 10mm very well, I have seen empties that were bulging pretty bad, kept me from getting the full potential out of the cartridge.
Most factory ammo is almost like the .40S&W, not worth going to a big gun for that performance. I should have bought a KKM barrel and kept the G20. I found some reload data from IMR using 800X that were amazing. IMR removed the hot loads in later revisions of their data.
The real 10mm, not the watered down versions, were designed to be the perfect handgun cartridge. Good bullet diameter, velocity, comfort control. I agree.
