Aluminum Frame / Steel Slide

[Tazman11]

I build and tune 1911s. Since I started using this, I don't use anything else. It doesn't dry out, run off the slide, and stays where put. Plus it's inexpensive at Amazon. 2 8oz tubes for about $18

I find it funny that no one seems to remember the ground breaking Model 39 and those later generations of the 39 and 59. Most were alloy frames with steel slides, with a few rare exceptions.

We used them starting around 1974 in my department, 39s and 59s, later on 469s, 669s and then third generation models. Never heard of a wear problem, we just used regular gun oil.

...my 1992 vintage 6906 is sitting right here. It was my personally owned duty gun for 10 years...well over 7k rounds fired with one failure to cycle what I could feel was a weak round during a qualification...

Always used the Shooters Choice grease on that one also and there is very little wear to the rails...

My dept started issuing the Mod 39 in 1967 and continued issuing S&W alloy frame/steel slides until 1999. 39, 39-2, 439, 469, 5904, 6904.
One of our main range officers once said the way to tell if you've got enough oil on your S&W was when oil ran out the bottom of your holster and down you pant leg. Maybe a slight exaggeration.
But his point being if the part moves or slides then it needs to be lubed. That use to be pretty much the norm for guns until Glock came out with use only 5 drops.
