No one's mentioned it but I will. The 3.8" barrels of the G29 & G30 may not deliver the quoted velocities. You probably better consider that in your thinking.
Also, I've shot G29s, carried G30s and currently own a G21, a G20 and a G20T. The recoil of the 10mm as experienced in the Glock is nothing like some would portray it to be. My personal opinion is that 230g +P 45 ACP rounds have more felt recoil than full power 200g 10mms (I've shot both the Double Tap and the Buffalo Bore). YMMV!
