Bingo. The .45 acp round with a 230 gr bullet was designed for the 5" 1911. With that barrel length, it will acheive the design velocity of ~830 fps.
With a shorter barrel, you get less velocity and the likelihood of expansion drops.
Two ways to regain the lost velocity. Either use a lighter bullet (200 or 185gr) or keep the 230 gra bullet and bump up the powder charge (+p loading) which increases the recoil, making follow up shots more difficult.
