Of those listed, the 38 Super and .357Sig will have the flattest trijectory. The .357 Sig, even in a compact polymer like a glock, let a lone a fullsize metal framed Sig226, is going to have much less felt recoil. If you think that the 1911 platform will make up for this, then go with the 38 Super, as I don't think there is a 1911 make in .357Sig.
