Just curious.

Yes, some. But, not nearly as effective as it would be if you were using a .38 super or 10mm.

The .45 is a low pressure cartridge and pressure is what is needed to fuel the comp. For best results you can use light bullets and load them hot. Slower powders may also help.

I've shot one compensated Kimber .45 that was using 155gr frangibles over Bullseye. It was very pleasant, but not exactly flat.

A .38 super in a 1911 can be made to recoil with nearly zero flip.

I just built a comped 1911 Frankenpistol in 45 ACP. I too found light bullets loaded hot kept the pistol shooting flatter. Noticably less than with standard 230 hardball loads.
