    Union switch & signal recoil spring plug question

    What kind of machining does the face of an original USS recoil spring plug have? A picture of an original would be great. Thanks.

    US&S got their recoil spring plugs from sub-contractors, so there is no true US&S recoil spring plug. A division of Remington Rand manufactured recoil spring plugs, and that may very well be what you have.The barrel bushings were bought in a semi-finished state, and this probably led to most of the US&S bushings still having machining grooves on their face.

    On a few US&S 1911a1's I have seen have the concentric circular machine rings on the barrel bushing. I certainly do not know if all were like that.

    Not all bushings on the US&S have the circular machining. Just depended on how well they were finished when received or how well the workman wanted to finish them.

    Both of mine have the bushing rings.

    FWIW, I have an early version and a late version. Both have the concentric rings on the barrel bushing.

    There is no difference in early or late production as all the bushings were contractor supplied.

    A quick count showed that two I have don't have the concentric rings, one has very obvious rings, and one barely has any rings. I never kept a record of this on the ones I no longer have.

    Most US&S bushings will have the concentric rings. However, having owned dozens of them and examining countless others, I agree with Johnny; not all have the rings. The important thing is that they have the proper Du-Lite finish, and that condition and wear patterns match.
