The bbl is not that short. Vel loss in the 45acp isn't as critical as other service rounds, it's designed to expand going slow. I get good expansion from my 1911OM using just about any of the majors JHP. If you are really worried, drop to a 185gr or 200gr XTP JHP for higher impact vel.
"Given adequate penetration, a larger diameter bullet will have an edge in wounding effectiveness. It will damage a blood vessel the smaller projectile barely misses. The larger permanent cavity may lead to faster blood loss. Although such an edge clearly exists, its significance cannot be quantified".
