    I picked up the hammer and true radius sear pack over Black Friday.
    I will be installing them in my old MC Operator.
    I don’t have experience with this, but I want to learn. Will I need a new thumb safety? I know there may need to be some filing.
    Thanks

    No disrespect, as you may very well have the skill set for this. "I don't have experience with this, but want to lean" is an admirable trait! Keep in mind, learning the firing system is at the top of the food chain. Best of luck.

    The ones I have installed on springers there was enough left on the TS that it could be refit to the new sear. Not guaranteed but it should be able to be refit.

    First. Please be safe. This is one of those gun could go full auto installs.

    Second. Read, read, and read some more on the proper install and relation of parts with visual diagrams.

    Third. There are no drop in parts in 1911s so the safety could work or it could not.

    I just ordered my Third set....

    They practically drop in, and if I can do it, you can.

    I love them.... Almost as much as my first born :D

    Just take your time and be careful.

    Set 1....

    Harrison parts are as close to drop in as you can get. I've always been pleasantly surprised with the quality of anything I've ever gotten from John. I just put in a TR ignition set in a Colt Gov't Model Series 80 and like everyone above it went smoothly. TS could go either way.

    Add me to the Harrison fan list. The hammer and sear dropped right into my SA loaded. I also swapped out the TS to one of his as well, which did require fitting. But he has a how to on his website that made quick work of that.

    I had to do quite a bit of filing on my original thumb safety. I did end up purchasing a Harrison thumb safety later.

    In hindsight, I should have just kept my stock thumb safety, hammer, and sear in a bag. That way, if I sold the gun, I could easily bring it back to stock.

    Best of luck!
