The only issue with .45’s is that many women and a few men do not have the hand strength / length of finger to properly control a 1911 in .45 ACP. Since there is a need to standardize ammunition, the only way you can compensate is to either:
1) go back to issuing .38s to females
2) order the .45 as a compensated model
Qualified expert back in ‘83 with a 1911 that was so warn it barely stayed together. You could shake the pistol and have the slide rattle.
Yep, that's just what the sidearms were for tankers back then. I ran the arms room for my company and they were all that worn.
These new versions of the MEUSOC M45 pistol cure the sight problem with Novack high visibility sights; a trigger job for a light and crisp trigger pull; a new trigger that is longer, fits, and minimizes over travel. The other things are fixed by training -- assuring the trainees that the gun will NOT break their wrist and recoil is manageable. Reassuring the trainee that the muzzle blast will not kill them. Imparting confidence in the trainee that they are the master of the pistol and not the opposite way around.
Like me; I’m a pretty small guy, and it’d probably be fairly difficult for me to control a .45 well enough to consider myself confident and proficient.
