What is the ridge on the bottom of the slide called?

What is the ridge on the bottom of the slide that pushes forward on the case head to strip the round out of the magazine called? I think I need to deburr mine, and I realized I don't know the jargon for that feature.

 

[Jim Watson]

Some call it the Stripper Rail.
On a 1911 it is more often called the Disconnector Rail.

Why do you need to deburr it?

Will be starting a new thread on that soon...

I'm gonna google "stripper rail" and I'll bet I don't find many results that are SFW. ;^)

Results of that Google search were surprisingly low on the entertainment factor.

I'm probably on a list now, though. Or *another* list.

Also called "disconnector" rail. Note the little "scoop" toward the rear. This allows the disconnector to move up to allow the sear to disconnect the hammer!

It would have to be really bad to affect slide function. Pictures would help.

Breech face

When I worked in a large gun manufacturer, that part was called the hammer ramp.

Breech face

This is my definition as well. In many examples I looked at, I see some variation of, "The lower part of [the] slide bolt face catches the top part of cartridge rim and strips the cartridge from the magazine..."

A little more info!

The area in question is called the central slide rail on page 83 of Jerry Kuhnhausen's excellent reference book The U.S. M1911/M1911A1 Pistols & Commercial M1911 type Pistols - A Shop Manual (Volume 2):

4. Breech Face - The cartridge seat and breech face area below the seat must be sufficiently smooth to allow unimpeded cartridge feeding and cartridge rim engagement by the extractor. The 45-degree edge break at the coincidence of the bottom of the breech face and the central slide rail must not exceed the ordnance specification of .001"+.006".

Don't do it. I asked about a mooning tool here; it wasn't pretty....
