Operating slide types

[Milsurp Collector]

Here are the different types of operating slides classified using the Carbine Club system and the system used by Riesch in US M1 Carbines, Wartime Production:









I bought two slides just to make these pictures and put some time into taking and composing the shots so if you share them please give credit where credit is due. Thanks.

Are the very last pictures on the right for Types IV, V, and VI correct? The distance from the end of the cam cut to the slide stop hole doesn't look quite right for some reason. - Bob

I probably should have gone looked in one of the books before posting, but I thought the last two types should look the same, but different than the Type IV.

I think it's just the way the pictures are and the different amount of wear on the different slides.

The cuts themselves are very close so it's hard to see . Look at the bottom of the ouside curve of the slide behind the cut and note the thickness of the metal between the outside curve and where the back of the cut makes the 90 degree ( well , less than 90 ) bend upwards . See the difference in the amount of metal in that triangle - ish area . The turn is more forward so that the slide has to move further to the rear before the bolt lug starts to move up.

Yep, I see it now. At first I thought the last pictures on the right for Type V and VI didn't look exactly the same, and I thought they should. I was looking in the wrong place, and of course they both are definitely different than the Type IV above them. Thanks! - Bob
