I want to change the mainspring housing on my WWI-era Colt 1911 pistol. I did this years ago on my 1991-A1, and changed back again; but I’m having a memory lapse.
Here’s the scene: I’ve removed the housing. There’s a pin that goes back to front at the top of it. (As opposed to the larger lateral pin that holds the housing to the frame.) I’ve pushed out the little pin. What I expected was for the mainspring to shoot across the room. (I’d put a towel over the end.) Only it didn’t. It’s still within the housing.
So the items are just not sliding out of the housing, right? Are there any burrs on the bore of the housing that could prevent their removal?
Could a small strong magnet pull them out? Or maybe a piece of dowel rod super glued to the plunger would let you pull it out. Is there any way a fine piece of music wire would fit between the plunger and bore to allow you to work it out?
I’ve not disassembled a 45 for some many years, but my recollection was that they kind of fell out.
That is the case. I’m guessing there might be a burr somewhere (assuming there’s not a ‘trick’ that I’ve forgotten – and I didn’t notice one on the forum), but I’m not seeing one. It’s like the retaining pin is still in.
I do have a back-up plan. If I can’t get it out I’ll just get new parts and put them in the ‘new’ housing.
I just got a phone call from a friend of mine who’s into guns. (I mean really into guns.) After I told him the problem he called a friend of his who’s a 1911 expert. When he called back he said that his friend said that sometimes on older guns (mine was made c.1917) the mainspring cap can wear a groove in the housing. I’m guessing that’s what happened here; maybe it made sort of a ring it can’t get past. The FOAF suggested squirting in some 3-In-1 Oil and working it to see if it comes loose. If I have any oil I’ll give it a try. But right now I’m thinking I might just go ahead and get new parts.
My friend emailed that he got the parts from his friend, so I’ll just keep the old parts where they are and put new ones in the housing that doesn’t have the lanyard loop cut off.
Only I decided to put the gun back together for now. I cocked the hammer, but it won’t drop when I pull the trigger. Probably didn’t get the sear spring in right. I’m too sick and in a rotten mood right now to take it apart again. (Being sick always pisses me off.)
