A 1911 project (Modem warning, photo heavy)
Posted: Wed Feb 25, 2009 4:18 pm
Since this section doesn't get a lot of action, I thought I might add a bit.
A while back, I noticed a new Springfield Champion at a gun show and bought it.
As soon as I got the gun home, I contacted Brownells Gunsmith Supply and ordered an Ed Brown bobtail mainspring housing and a jig. I had carefully inspected the gun and found that the frame was .020 out of spec, with the mainspring housing resting too high in the frame. This was most evident when looking at the butt/heel of the pistol grip.
Not wanting to deal with that misfit with the new housing, I offset the new retaining pin hole .020 (using the jig) to let the new housing sit flush with the grip frame.
This presented me with the expected problem of having part of the original holes left in the frame after trimming it to match the new mainspring housing.
I gently placed the frame in my vice and using an acetylene torch, loaded the 'divots' with nickel brazing rod then dressed the excess material down to match the frame and finished the fitting job. This picture was enhanced to show the slight differences in the colors of the base material and the nickel.
I liked the original grips and wanted to keep them. Upon examination, they appeared to be some type of mycarta or resin impregnated wood, so I filed them down (rather than attempting to saw them) and lightly polished the dressed edges. I also cut a relief in the underside so they would clear the mainspring housing pin.
Once back together, I shot the pistol for the first time and found it to far exceed my expectations. (Sorry, no pictures of any targets)
Since I had bought this gun as an alternate carry piece, I elected to purchase good gun leather for it and found that Lightning Arms had a Del Fatti pancake type holster that would fit it.
In the end, I had a fantastic pistol that didn't print (no sharp corner on the grip frame), shot well, and was a joy to carry.
If any of you fine fellows are interested in doing your own bobtail job (I recommend this be done only on a stainless pistol), send me a PM with your mailing address, and I will loan you my bobtail jig and #2 center drill.
