Aw Cummon Abilene
There ain't nothin in the Great Book of All what says one has to shoot ones Cap Guns "one handed." Cap Gunz can be shot in any cattle gory. The dualist requirements do specify "one handed."
On the other hand (cool Segway, no??), Capt. Baylor may just be tired of cleaning Cap Guns. Cartridges do be some easier . . . mostly.
Also, when faced with the mostly assured possibility of RAIN, in may well behove one to forego the Cap Gunz to insure the Fuego. Could be.
I have no clue.
