I’m mostly an M&P guy but my preferred outlet (Floyd’s) doesn’t do slide milling for Sigs. I want to put an EPS on my P320c; where does the hive mind reccomend for quality work of this type?

I think it is because the Sig slides are very hard and they eat the tools.  Those milling tools can be quite pricey.

Many Sig slides can't be milled because of the deep underside cuts.  P320s almost require a factory cut or a new slide.  My P320 could not be milled so I got a new slide.

Jagerwerks does P320 milling. Their page has a couple helpful photos to show the interior cutouts that preclude them from doing top forward serrations and optics cuts.

Mine too! I send these off to Parker Mountain Machine, they are who my Sig rep recommended.  I have a P229 with them right now and it's in .40 too...

SIG P320 Slide Milling

Thanks for the link. I sent them a messaged asking if they can do the undercut on a Sig320 slide I came into a while ago. Sig stated they wouldn't do it as it is not attached to a specific serialized FCU to document it against.

The uncut one is on the left. A newer slide I got to build up an M17 clone is the right hand slide.

Sig does slide milling as well? I don’t see it on their custom works site, but I guess I could always call. If the price is right I might have them do it. I have an older 4” P320 slide that would be a great home for my Romeo-X but buying a new X Series slide isn’t much more than Jagerwerks or CHPWS, and the new slide would come with the X series day-night sights that I really like over the Siglite night sights. Also might be better from a warranty or legal perspective (if it’s ever used in a defensive shooting or if it just goes and does its P320 thing) if Sig did the work.

I believe he’s referring to the upgrade modifications that SIG does on older P320s under warranty because of the drop (un)safe issue. He’s saying that SIG won’t do that modification to his slide (the one of the left) because it was a slide he acquired separately, not as part of a pre-upgrade complete pistol.
