Say you picked up a new Springfield Mil-Spec... What would you swap out/fit/replace, with non-MIM parts? I'm guessing the extractor is MIM? Is this right? What other parts? I saw the tacked MIM thread but it looks less than authortative for Springfields.. What should be replaced/fitted new parts for? |
DON'T FORGET THE HAMMER STRUT AND ALL PINS!!!! |
Jeeze, even the hammer and hammer strut, and all the pins, are MIM??? Ouch...what I thought was a deal just turned into a ..not so much of a deal... |

If it is your range gun, you COULD just shoot it until something breaks. If it is your CCW/daily use weapon you'll want to get it all tip top. Murphy's Law and all... The slide stop and recoil guide rod broke this year on my 1911. ~15 years into its life. Easily replaceable parts while I was in there, I swapped out the recoil spring for a Wolff (suspected culprit for the guide rod damage). Probably 10k rounds through it without a problem before that, though. |
Oh, I firmly plan on shooting the wee out of it at the range before I change anything  It's a Springer Mil-Spec..in .38 Super. This probably changes some of the parts  Brownells doesn't seem to carry much in the way of .38 super specific extractors, for one... |
Considering this will wind up being a carry gun, that's really not an acceptable thing..if I ever truly need it and the stupid disconnector snaps in half? That's not a pleasant thought. There's a reason ordnance specs for the 1911 specced every part to be forged and not cast.. |
Seems like if an MIM part is going to break (low impact), then it will break relatively early in its lifetime. I didnt replace the pins or hammer strut in my Kimber, but I did replace all the parts SGB listed above. My thumb safety will stay. I've used it quite a bit and it hasnt broken, and I'm not worried that it will. As it is right now, I trust it enough to use it to defend myself and those I love. Hell, to be totally honest, I trusted it when it was full of MIM parts as well. The USMC didn't seem to have any issues with their MIM Kimbers. They trusted their lives to them as well, and beat the crap out of them alot more than CCW'ing would. To answer your question.... Things I would immediately replace are the extractor, FP stop, and slide stop. Shoot 500 rounds. If nothing breaks, chances are it never will. |
| Are there any online DETAILED photo essays for disassembling a 1911 to replace mim parts? I've already replaced my slide stop and the barrel bushing is on the way, but I'm thinking of doing the other parts too. Unfortunately, I don't know how to disassemble it past field stripping and I'm not gonna experiment on an expensive gun. |
fairly simple, I've done it twice already to my own gun using this guide: www.m1911.org/stripin1.htm Using only the parts from the gun itself (intended design), having said that, an AR15 firing pin (bought one at the gunshow just for this mission) works perfectly for taking apart and then putting back together. Eugene Stoner was a pretty sharp engineer too .edit: Another good guide I have used: www.coolgunsite.com/disassembly/disassembly.htm The 1911 Pistol Is Its Own Toolbox! google search terms: 1911 disassembly |
