I took Dad’s 1911 out of storage for the first time in a long time. I have not fired it since I was a kid, and when Dad last used it, he cleaned it before storage. I want to field strip it to clean it before I fire it this weekend, but the little doohicky that needs to be turned to remove the spring is too tight to turn all the way. Is WD40 or penetrating oil ok as long as I clean it up right away with Hoppe’s, or should I see a gun smith? The .45 is a family heirloom, but I understand that it is also valuable, so I don’t want to f it up. BTW, I carried a .45 for the first 3rd of my Marine career, before we switched to 9mm NATO. I shot expert with the 9, and barely qualified with the .45, but I still liked the 45 better. I’m glad to see that we are going back to the .45. Thanks
Update. My gun store fixed it in about 10 seconds……just a little dried grease.
