You mean you can take a bolt apart???
Seriously folks...........down here if its metal (carbon steel) and you don't oil it in a matter of days it will look like the handrails on the Titanic (now...........not in 1912). Sure you can over do it, but it must have some type of rust preventive.
The USAF used to issue what was called the "Air Force Premium Grade" 45 Auto. It was a 1911 stripped down to the frame with all the parts being thrown in the junk pile, then completely rebuilt, by hand , with match grade parts, by the armorers at the gunsmith school at Lackland. It was a thing of great beauty,,,,,well really it was ugly as hell but shooting the way it did made it beautiful. It was guaranteed for 1" at 50 yards (Yea like I could tell with my 3 inch wobble). Anyway, when they came from the shop they were tight I mean tight, as tight as well lets just say tight
. Took at least 500-600 rounds to get them to be reliable. One of the best ways to shoot them we found was to literally douse them in 3 in 1 oil. I mean squirt gobs of it in the slide, in the magazine, on the cartridges, on the recoil spring. I used to go through a can of the stuff while firing the 90 rounds of 45 caliber during a 2700. Team mates did the same. Hell we were the main reason the BX stocked the damn stuff (3 in 1). Now we DID clean em off after a match, but rest assured it was oiled, well oiled (the firing pin too)! Course they were not combat weapons and never (well almost never) got dragged in the dirt, mud, or sand. Sure oil it but don't over do it.
