Buckskinner:
I am an elderly, cranky, mean-tempered old reprobate … but only on my good days. I came in at the beginning and by the grace of God I’m still around. I see by your first post that your pistol fell apart while you were at one of Awerbuck’s classes, and that puts you in with some very good company. I presume therefore that you’re serious about your pistol in the role of a weapon.
Now get ready for a lesson …
Take that new plunger tube and look at the ends of the little posts. They should be hollow on the end. This is so they can be flared out in the manner of a rivet. The holes in the frame should be countersunk as previously explained so that the post(s) have a place to spread out in. Cast parts are sometimes brittle, and crack rather then flare. I suspect that the first tube is indeed cast (cheaper to make) and that’s part of the reason it came off.
You may, or may not know it, but that little tube is a critical part. If it comes loose the spring-loaded pin that pushes against the manual safety can slip under the thumb-piece (sometimes called a “paddleâ€) and lock the safety in the “on†position in a way you can’t get it off. Not good at all.
Jeff Cooper went so far as to advocate that the tube be silver soldered to the frame, and for years I did exactly that. And while this might be seen as overkill none of them ever loosened or came off. And for still more insurance I glass-bedded the left grip panel as I described before. You might say I’m a “belt & suspender’s man,†but my sidearms have always worked as expected.
I have owned a fair number of .45 pistols, and not one of them had a manual safety that was so far out of tolerance that it rubbed against, or otherwise touched the plunder tube. And certainly not to the degree that it could cause the tube to loosen and come off!! I am absolutely delighted that all of this happened while you were in a class because I can think of some less fortunate circumstances. On the other hand I am somewhere between disgusted and outraged at what passes for a serious weapon these days. The difference between “a pistol†and “a serious pistol†is that in the latter a competent builder pays attention to the critical small details as well as the obvious ones.
In over a half century of shooting M-1911 pistols I have never had a part “fall off†except for one front sight. And when I put it back it darn well never moved again. Front sights and firing pin stops are two other critical parts that are overlooked also.
Finely … it is obvious that you intend to do your own work, and have gone to the trouble and expense of buying the necessary tool(s). But before you start I respectfully suggest that you get a little education first. Go to (
www.gunbooks.com) and buy one of Mr. Kuhnhausen’s shop manuals on the Government Model .45 – which is well illustrated and equally well written. When you are done reading it you will know substantially more about the subject then you do now, and many mysteries that confuse you will become crystal clear.
Lesson over …..
The Old Fuff will now go back into his cage.
