i have a G20 and G29 (and C.D.E.) with a good bit of 10mm ammo. i dont shoot the 10mm much anymore now that my wife and daughter are more in to shooting. i will keep my C.D.E. for the occasional hunt and just to have a 10mm, but if really considered trading the 20 and 29 for a 21 and 30. this is because i can get more paractical use from a .45acp than a 10mm. this is not a caliber war debate. i would still have a 10mm for woods carry and the occasional chance hunt.... so, if you had a 10mm that already fit all of your 10mm needs, would you trade your G-10mms for G-45acps?
