When I was active in IPSC, I switched from using 1911 style pistols to a Glock 24C. I actually enjoyed using that Glock, but its unusually sharp grip angle (compared to that of a 1911) made acquiring the sights more of a challenge. I only resolved that issue by being one of the first in my club to start using a parallax-free red dot scope. Among its many virtues, the 1911 and its many derivatives have a very natural grip angle, which helps in quickly putting sights on target. What I'm saying is: both are good choices, but for a rapid sight picture, I would choose a Hi-Capa.
