A couple of problems with nitre bluing. Because of the high heat involved, it's not recommended for things like frames or slides. It is also a very fragile finish, it will be rubbed off after you holster the piece a few times. I use nitre bluing on non-critical pins and screws. I don't know what tem...

The slide will move back and forth but bolt can't lock. If you pull the trigger group you should be able to see the bolt carrier. Next you need to align th...

Dump them out on some newspaper for a few minutes and size them. You can make this lube by mixing liquid lanolin and 99% is...
