    [​IMG][/IMG]I recently added an extended beavertail, replaced hammer, and trigger to my SA 1911 milspec. Here is my parts list and how I did it, for those who are thinking about this modification. I am not a gunsmith but am pretty good with mechanics. This may not be the correct way, but it worked for me.

    I bought all parts from Brownells. Part Number

    1. S & A palmswell blue 220 high grip safety 849-009-027
    2. Wilson combat 455B 1911 auto value line hammer 965-314-110
    3. S & A 220 degree installation jig 849-009-000
    4. Dlask medium 1911 ultralight trigger 253-101-003

    These parts were less than $100 to my door.

    First I tore down pistol to bare frame, pay attention to how things come apart and reference parts breakdown for any issues.

    Next I tried to fit new trigger. Would not fit. To get an idea of how much material needed removal I used a micrometer to measure od trigger and started removing material from top and bottom of trigger assy. I had to remove about .007 thousands to make trigger fit. I used a diamond wet stone for this, I also stoned the trigger loop rails. I wish I would have purchased a trigger track stone, as the track im my pistol was not perfectly smooth.

    Now it was time to fit hammer. My hammer required no fitting, as it engaged and functioned very good.

    I removed all parts from the frame again and installed my beavertail jig. I started with a large flat file and began to remove material from the rear of frame. I wish I would have put tape below and above jig on the frame to protect it from missed strokes on the file. I continued filing until I could feel the lesser resistance of the file when I was no longer removing material from the frame and was just hitting the jig. This required installation and removal of the beavertail multiple times to get enough material removed.

    I cleaned frame installed all parts, and tested safety. Function worked as designed.

    Note: I bought a super black, flat black touch up pen, to touch up frame. I did not like the apearance of this, as it ws just flat black paint. Next trip to gun shop will buy flat black blueing pen.

    I'd love to see these pics - I have a GI and have considered adding a beavertail. I'm on the lookout for a stainless milspec/gi as well, as you wouldn't need to refinish the frame! I'm guessing you'll end up wanting to reparkerize the frame before you're truly happy with the finish.

    I'm waiting on the parts to do this myself so thanks for the pics and info. I am planning on refinishing the entire frame while I have everything apart so I went a step further and ordered some coyote matte finish for the frame and plan on a two tone setup when I am done. The refinishing paint I ordered is supposed to come out looking like a matte finish, which is supposed to match up well with parkerized blue finishes. I don't want anything shiny on this gun.

    First thing I will need to do is find someone to beedblast the frame for me, but everything else I will do at home.

    When I am done I hope to have this end result with the exception of the slide release and thumb safety remaining parkerized.
