    I am considering getting a series 80 Colt, but I prefer a short trigger and arched mainspring housing.

    Will an original series 70 short trigger fit in a new series 80 without any modification?

    Would replacing the mainspring housing require any special fitting?

    I'm no gunsmith. Are these modifications something best left to a good gunsmith, or something I could easily do myself?

    Thanks.

    It shouldn't be a problem. I swapped out both on my NRM 80. I prefer the old school arched mainsprings. I also removed the series 80 safety and replaced it with the piece from Brownells to fill in the space. Here is more info taken from 1911 Forums:

    Both are pretty much drop in parts.

    Adjusting the take-up and overtravel isnt hard, and thats about all there is when installing a trigger. With some triggers you cant adjust take-up or overtravel without modifying the trigger. The Colt trigger I put in my SA milspec didnt have provisions for either, neither did the SA trigger it replaced.

    If you can detail strip it and get it back together, you shouldnt have any problems. If you cant deail strip it, have a smith do it.

    Yes, they will swap out, and yes, you can do it if you can detail strip the pistol.

    If you don't know how to detail strip a 1911, go here.

    Go here for trigger installation details.

    The other choice is a new production series 70 which already has short trigger and arched MSH, but I don't like the look of the stainless hammer. Can you get an all blued spur hammer for these? I can't seem to find one available.
