The G29 and G20 were designed from the ground up for the 10mm. They are not another design that was adapted for the 10mm. I shoot both Underwood and Swamp Fox ammo with no problem. DT and BB as well.
The guy who owned Swamp Fox ammo (RIIP Mike Willard) passed away suddenly and I can't get more, but it was the hottest 10mm ammo I ever experienced.Both my Glock 10's handled it with aplomb. I have one box of Swampfox ammo left and probably won't shoot it as it's as scarce as the original Norma 10mm loads.
