Slide Models: P320 / P365 / P220 / P225 / P226 / P229 / M11-A1 / SP2022


This page is for non-optic-ready Sig slides, to upgrade your optic-ready Romeo1 cut Sig P320/P226/P229 slide to the RMR or Romeo1 Pro cut or add RMR holes to the Romeo1 Pro cut click here. To upgrade your P365 Romeo0 cut to the Trijicon RMRcc footprint click here.

**Holosun 509t, Aimpoint Acro, and Steiner MPS optics cannot be directly milled to SIG P320 slides and will require the slide to be milled for the Sig optic ready pro cut and the use of an adapter plate. There is an additional charge of $69.95 for the adapter plate needed.

**Some SIG P320 slides can’t be milled for a red dot due to the weight reduction cuts inside the slide.  If we determine this is the case, we’ll send your slide back at no charge to you.

**SIG P365 slides can only be milled for micro red dots (Holosun 507k/EPS, Trijicon RMRcc, Shield RMsc, ETC.).

**SIG P220/P225/P226/P229 slides cannot be directly milled for any optic due to the deep cavity for the safety plunger at the rear of the slide. The only option we offer on these slides is to mill our “cross” cut to the depth of the base of the rear sight dovetail and use our cross adaptor plate to mount the optic to the slide. The cross adaptor plate adds an additional $126.50 to the cost of the milling.

** Older West German Sig slides with a rectangular firing pin block cannot be milled for an optic or cross plate.

We reserve the right to call and suggest changes or improvements to your slide milling job.  Some slides can’t be milled and we will send them back at no charge if we determine it can’t safely be upgraded to an optics cut.

Shipping Instructions:
Safely remove the slide from your pistol. Remove all necessary internal components and iron sights if you selected to send your slide disassembled.

    Slide milling is awesome! They do a wonderful job of milling and finishing the slide. Very happy with the work and turn around time was less that advertised.

    Extremely happy with the slide milling they did on my P365. Very fast service. They called me on a Monday saying they received my slide, went over the options that I chose, and I received my slide back in the mail the following Monday.. I’ve recommended their services to several people already and will definitely use them again. Top notch!

    Very happy with my milling service on my SIg P320C. I shipped my slide on April 4th and received it back on April 27th. I was also advised that you had some machines down which backed up the work load, slowing down my turn around time. Still VERY happy with the work ya’ll did. Thank You CHPWS!
