Bad fit; destroyed my barrel bushing - DPM 1911 5in Bushing Barrel 10mm Auto / 460 Rowland Mechanical Recoil Reduction System

Do not buy for 460 Rowland. The OEM guide rod from 460 Rowland is skinnier, in order to clear the barrel's compensator. This DPM kit does not account for that. When fully assembled, the guide rod hits the comp, preventing the slide from racking back. This also prevents proper disassembly. I had to make several attempts at racking the slide off my workbench before the barrel bushing failed and sent pieces flying. At least I was able to get this thing out. Now I'm stuck with a barrel that has half a bushing on it, and no easy way to remove and replace it thanks to CA requiring the comp to be pinned and welded on.
