I have a savage/springfield 67f that was in storage for 20+ years. I wanted to clean it before shooting it and ran into problems with reassembly. Here is what happened

- Check gun is clear
- remove stock
- remove pin and screw to drop trigger assembly
- it was spotless so I added a few drops of rem oil and reassembled

Now when I dry fire the slide will not come back unless I push the slide release button. What did I do wrong? Did something fly out when I disassembled, did I reassemble incorrectly or is something else going on?

Thanks for any help
