I’ve often thought, with no proof, that semi autos where the slide runs on short sections of frame “rail” should be less lube sensitive than semi autos where the slide and the frame “rail” make contact over a long section. Former would be Glock, latter would be 1911.

I only have one 1911 and it is very lube sensitive. It has to be visibly wet to be reliable.

I have a Luger which is not lube sensitive at all, despite having long sections of interlocking upper (not really a slide) and frame. But the upper moves very little, almost all the movement is the toggle, and you’d need Locktite to slow that thing.

Further, shorter sections might make the gun more tolerant of sand as the groove in the slide could be more easily cleared.

So I wonder if anyone has cut away pieces of the frame rail on a 1911.

I’m not using the right terms here.
