1911 Reassembly Fail
« on: December 14, 2020, 11:44:17 am »
So, using the videos on the original DVD that came with the gun, and a pictorial how-to from the internet (these ones: http://how-i-did-it.org/detail-1911/index.html and http://how-i-did-it.org/detail-1911/reassembly.html), I took the bottom end of my RIA GI model apart and then put it back together again.

The video is a bit lacking, such as when removing the thumb safety the demonstrator simply pulls it off.  You can't see in the video that he moves it to the mid-point before pulling it off, and no mention is made.  Once I read it in the above instructions, it was easy-peasy.  Ditto on the removal of the mag release button - easy when shown but not easy when just following the video.  Still, between the two, everything came apart without apparent damage.

However, in putting it back together, neither gives very clear directions or pictures on getting the sear spring properly located relative to the sear and the disconnector, nor the hammer and the sear/disconnector.

When reassembled, the thumb and grip safeties both correctly keep the trigger from being pulled while the other is disengaged.  My problem is that when I manually cock the hammer it doesn't stay cocked each time.  If I try cocking it without engaging the grip safety, it won't lock every time.  With the grip safety disengaged, it sometimes stays cocked, and sometimes just goes back forward.  I don't think it's supposed to do that, but this is my only 1911, so can't test that theory on another working example.

Help!?!

    (Caveat: I know nothing about the intricacies of 1911s)

    First thing I'd suggest is taking it back apart, and making sure that you can do that without having to pull on anything too hard.

    Is this a better video?

    The sear spring just sits behind everything.  Or, on top since we usually don't assemble the guns in firing position.  Sounds like the sear spring foot of the sear spring is in front of the sear, not behind it.

    Nothing in the video about the lower, let alone the sear spring.

    This image shows clearly how the three legs of the sear spring should appear when viewed through the grip safety:



    My guess is you will find that on your gun the longest spring leg on the left is on the other side (front) of the sear foot.  This means the sear only engages when it flops to the right position.

    Hope that helps.

    That's a great picture.

    And, yeah, if I recall correctly, that leg did go in behind rather than on top when I put it back together.

    I was basically wanting to see what it would take to clean up the trigger, but it took longer to get it apart than I thought, so just put it back together before going to bed.  I wiped most of the collected crud out (there wasn't a lot), but didn't do a true cleaning, since I figured I'd want to take it apart again to work on the trigger pull.  The video only ran about 4-5 minutes, and I know they went slower than necessary to be able to get in their commentary.  I took about 20 minutes to take it apart, and at least twice that putting it back together.  But I understand it better now, so the next time won't shouldn't take as long.  Years ago it took ten+ hours the first time I rebuilt the carb on my car.  Over the next ten years I tore it apart enough times that I could take it off the engine, tear it apart, clean it, put it back together and have it back on the car in only two or three hours.

    It was a decent video, but he only went over the top end.  I didn't mess with that part.

    You are spot on. You get faster. First time I did a detail strip of a 1911 it probably took a couple hours.  That time did include a good scrub, but it was still a slow process.

    I picked up a used P226 from my FFL last Friday.  Yesterday was my first time taking a Sig P series completely apart.  During disassembly I missed a spring that could have been de-tensioned before removing a pin, and when the pin came out it shot three parts out the magwell.  At the time, I didn't know it was three, and I only found two. 

    Fast forward about an hour and the gun is all back together and I am function checking it.  No single action.  DA worked fine, but once the hammer was cocked, the only way to drop it was the de-cocker.  Realized there must be a missing part, found it under the desk, put it in and boom, all works!

    Doing it is the key part.  Knowing your gun in detail is, imho, a big part of the needed positive attitude to run the gun well.

    IT LIVES!!

    Well, no, not really.

    But it does work correctly again.   :clap


    Thanks again for the help.

    Glad it worked out.  Still waiting on a new disconnector/trigger bar for my Sig
