    I shot the 45 ACP in 1911's, SIG 220's and some other pistols for years and then drifted away from that cartridge while pursuing other endeavors. Most of that shooting was with the 230 grain bullet weight.
    I recently returned to playing with the 45 ACP and was instantly reminded that it is a great cartridge. On this recent journey I decided to go with the 200 grain SWC (H&G 68 style bullet). Both bullet weights (230 & 200) perform very well in the 1911.
    While you can push a 45ACP pretty hard, there's just not much to be gained doing so. Why beat up the pistol to get a few more fps?
    About 1963, I decided to hot rod my Remington-Rand with some loads recommened by Jeff Cooper. The bullets were 200 grain cast really whistling down range with a mega dose of Unique. All was good until about the 10th round, when the firing pin stop hit the ground followed by the fireing pin and spring. It took some time crawling around in the West Texas dirt to find all the parts. After a good cleaning and reassembly, the pistol worked just fine for several more years with normal pressure loads.

    I have been cured of hot roding a 1911 pistol since that day.

    Char-Gar - EEK!

    NOT what you'd want to happen during a self-defense situation, even WITH a backup pistol...

    Used mostly near Max loads of Unique back in the day, burns a bit dirty but works reliably, with Cast (fairly hard) 230 Gr. LRN boolets mostly, now I want to try some LFP's so am working towards that. Liked the J-Word (Speer?) JFP's back then but Cast is great in this caliber.

    I'd also put Wolff pack recoil springs in mine & a recoil buffer, longer frame life = less $$ spent on maintenance = a good thing. Didn't hot rod them but that last round has more slide movement due to no drag from the top round in the magazine, so those seem to help; Can see that the recoil buffer gets hit somewhat. Was mainly wanting absoute reliability, with good power & accuracy next.

    A 45 ACP cartridge that produces a velocity of roughly 850 fps with a 230 grain projectile will do a lot. I don't know what pushing it faster will accomplish.

    I guess it would depend on what you were planning on shooting with the load. I can see where someone could want more power but could not afford another pistol/cartridge combination.
    I wouldn't want to feed my 1911 a steady diet of the higher power stuff though.

    People tend to go on and on about how they plan to save the frame with this or that addition to cushion it.

    Unfortunately, the sharply angled corners of the slide near the breechface are stress risers for cracks as well, and the hotter the load the harder the slam the breechface takes. Nothing you do can lessen this force save not leaning on the throttle.

    I tend to agree that little benefit is obtained from exceeding 850/230. The extant hollowpoints perform well at that speed and hard cast or ball penetrates well.

    A gun run in its intended operating range tends to not only be more reliable, but runs reliably for a longer period before something breaks. A lot of this is intuitively evident but reminders have to be issued frequently sometimes.
