I carried my 43 in a JM AIWB long, I carry the 26 in a 19 holster. Printing is minimally different on me. Shooting the double stack is a lot better for me. With a 43 my trigger finger wants to go all the way around to go all the way through the trigger guard and drag on my left hand knuckle.
With full power ammo recoil of the 26 is dramatically softer and it tracks with a lot effort for me.
Slow fire accuracy better the two is just about equal though.
