This PF940C Compact package combines the popular OCS slide with a threaded barrel in a complete, ready-to-install kit. Designed for builders who want a factory-direct fit on OEM-spec frames, this package has been a consistent seller since we added it in late 2024. The slide’s weight, measured at 5.7 oz on our scale, contributes to reliable cycling and a balanced feel.

Frequently Asked Questions
Will this slide fit my aftermarket Glock 19 frame?
It is engineered for OEM-spec frames. We had one return where a customer experienced a “too tight” fit on a non-OEM-spec aftermarket frame. For guaranteed function, use with a Polymer80 PF940C or Glock® Gen 3 frame.
Is the barrel included and installed?
Yes. This is a complete slide assembly package. The threaded barrel is factory-installed with all necessary internal components (channel liner, striker, extractor, etc.) already in place.
What optics footprint does the OCS slide use?
The OCS slide is typically cut for the RMSc footprint, which also accommodates optics like the Holosun 407K/507K with the included adapter plates. Always verify the specific cut pattern for your optic model before purchase.
