In a hypothetical world where average 1911's were the same price as Glocks and had the same reputation for reliability, I would still choose a Glock over a 1911 simply for the mag capacity. Sure, we can argue .45 vs .40 vs 9mm etc, but finding a caliber you can put on target consistently is a whole lot more important than the diameter of the projectile. based on all the research I've done, I am 100% confident the .40 self defense ammo I use is more than sufficient to get the job done. And I can carry double the rounds, per mag, as an average 1911.....and that's with the compact Glock (mid-size). When you consider the purpose is for self-defense, that alone should be reason enough.
