In my conversations with Mr. Bidwell, he mentioned that one can do a good trigger job if
he follows the instructions that came with the Tom Wilson sear jig, especially when followed in combination with understanding the information in
"Pistol, Automatic, Cal. .45, M1911A1, National Match, SA-SIP-100" (Circa 1966) (Available here:
I have located two versions of the Tom Wilson instructions, one that says "REVISED" at the top, and one that does not. Here are links to the ones I have:
The copies of each that I have are old and hard-to-read, and even if they weren't, I can't attach them here in a size that would make them readable. Accordingly, I re-drafted them, including the graphics, and both versions are set out below, with the the original version first and the revised second. I found it VERY educational to not only read both versions but also compare them and take special notice of what was changed.
Obviously (I'm learning this the hard way), the sear-nose, hammer-hooks and interface work is about the most tedious and time-consuming thing in all of pistolsmithing, and I'm hoping that this thread will help educate us all about it. PLEASE FEEL FREE to add comments, additions, etc! I'll try to periodically go back and incorporate any comments, additions, etc. in an edit and hopefully get us a really good thread on exactly how to perform this difficult part of a trigger job.
