"I don't shoot plus p's in any of my old 1917's and with the relatively low pressure and velocities of the .45 acp, I think I'll be okay."
There have been concerns with the standard hardball load in the M1917 S&W for decades, almost from the time of inception for the gun.
Most resources recommending not shooting hardball .45 ACP through them because of the increased pressure and wear. A number of sources have theorized over the years that the very generous chamber throats on the M1917 were one way of reducing chamber pressures.
Most loading manuals show .45 Auto Rim loading information at reduced velocities with lead bullets.
I woudn't be worried about the barrel blowing out catastrophically, but I would be concerned with it possibly bulging if you've compromised the "native" hardening that was worked in when the barrel was made.
