    RI Wilson Compensator

    I have a Rock Island Tactical (full-sized) 1911. After reading about recoil compensators, I decided to try one. In Brownells they have a Wilson Multi-Comp (Wilson P/N 397). Supposedly, this will "drop in with little work"!
    Wrong!!!
    I've been at it for 8 hours. I finally have the gun assembled with the compensator, but it's been serious work.
    The RI bushing has an OD of 0.697 and the Wilson has an OD of 0.702. That doesn't sound like much, but 5 thousandths is a lot to take off with jewlers files and sandpaper. After I got the compensator to fit in the slide I discovered that the lock tang extends too far out and freezes against the spring cap. More filing.
    As I said, it's now assembled, but I need to clean it up a bit more to be happy with it. It shouldn't take a crescent wrench to turn the compensator!!! Should I try to get the finish repaired?
    Once I shoot it I'll report on what effect it has.
    BTW, I added a Wilsons spring buffer as well. Yes, that is mounted in the "most over-built part of the frame", but I didn't
    get it for that. If I can ease the recoil on the web of my thumb, is that a bad idea?

    From Brownells description:

    "Installation is as easy as fitting a new barrel bushing"

    Brownells mainly deals in gunsmith tools, parts, and supplies. So installation for a gunsmith is as easy as fitting a barrel bushing. The fitting you found necessary is typical for oversize bushings.

    If the compensator turns easily in the slide without the barrel, but binds with the barrel installed, then you also need to fit the inside diameter to the barrel. You may also need to add relief inside to allow lockup without "springing".

    Springing occurs when an unrelieved bushing prevents to the barrel from swinging up into lockup freely. This is tested by installing the barrel and bushing (or compensator) in the slide, and seating the chamber end of the barrel into full lockup. It should drop in freely and solidly, and should not try to spring back out.
