My first question would be what are you shooting it out of?

Standard 1911 was never made, nor will it hold up to shooting +P loads.

Even my Walther PPQ is standard 45ACP pressures.

Glock 21 Gen 4
5.2” KKM Barrel and 4.6” KKM
22 pound Recoil Spring
Wolff Extra Power Mag Springs

Really like the 5.2” KKM gives about a 50 FPS boost to velocity. Never considered a single stacked 1911 capacity to low for Bear Protection.
I normally carry 12+1 in both G20 and G21.

A good standard 1911 steel frame can withstand 45 super and 460 Rowland if certain modifications are done ! Would you like me to give the modifications required?

Thanks!
I'm good.

I have no inclination to go higher pressure.
I've already dealt with a cracked slide.
Although it was covered under warranty, I feel some responsibility for it also.
Bought the pistol used, unknown round count, or maintenance.
I put roughly 1,100 rounds through it.
I did replace the springs at about 600 rounds. After I found out that it was recommended.
I'm about due to change springs again.

My 1911 / 460ROWLAND says otherwise...

I shoot 45 super in my glock 21 also but i use a 24# spring and same barrel as yours. That frame can handle the full power 10mm, itll be fine with the 45 super. Have you unleashed it on a bear yet?
I should add, it still functions with standard acp loads. It doesnt kick the empties out but a few feet but never a malfunction.
