I've cut a bunch

Milling machine. Appropriately sized endmill, machine vise kicked at correct angle and away you go.

Or you can send your slide to me and I can do it for a fee.

^^^ what a nice offer.

Good job!

Fee and Free look alike but aren't =

I don't think he said free...

I think it was nice for him to offer to do it (as he is experienced) for a fee.

[yari]

I saw your post and had to reread kcs, I thought he might have said free.

Looked at my para lda slide. Doesn't have the scallop cut. Anyone ever cut one before? What's the easiest method?

I'm pretty sure you mean the disconnector scallop as the LDA slides are missing that.

Why does the vise need to be at an angle?
Seems like a keyway cutter is the way to do it.

He made no mention of a disconnector and I'm not a mind reader.

Ok, why does the vise need to be angled to cut the sear scallop?
Can you please show me a picture of one of the many sear scallops that you have cut so I can better understand what it is?

Isn't that a series 80 slide?

A series 70 has a scallop in it. I thought that's what the OP was talking about. For that I would imagine that a key cutter would work. I show about .400" in length and .165" wide.

No.
It's an LDA slide.

Series 80 still have a disconnector and a scallop in the slide to actuate the disconnnector.

No.

Ah, missed that previously...how do they do the DA ? There was a Seecamp conversion years ago, but it was pretty complicated how the rear was cutout and the DA trigger was connected together.

Is this Para LDA simpler?

That looks interesting. Although I'm not a big fan of the wide grip, I much prefer the classic narrow mag that the M19111A uses. The DA trigger is attractive though.

I take a 3/8" 90 degree boring bar with a 3/16" bit that has been ground down
and lay the slide on its side to mill out the Disconnector scallop. If you use the right size Key cutter you need to grind down the shaft for clearance. (just my easy way of doing it)
