Polymer80 PF940 Frame Names Explained
Last updated 24 October 2026.
The short answer
The Polymer80 model names tell you the size of the pistol the frame was made to match. According to Wikipedia, the line was sized to Glock-pattern parts. Match your slide, barrel and parts to the frame size, not to the brand name on the box.
Names and the pistols they were sized for
| Name | Size | Made to match (per Wikipedia) |
|---|---|---|
| PF940v2 | Full size | Glock 17, 34, 17L, 22, 35, 24, 31 |
| PF940C | Compact | Gen3 Glock 19 and 23 |
| PF940SC | Subcompact | Glock 26 |
| PF9SS | Subcompact, single stack | Glock 43 (Gen 4) |
| PF45 | Large frame, .45 ACP | Glock 21SF |
Compatibility lists like this are general guidance. Fit still depends on the generation of the parts and on tolerances, so check the listing for the exact part before you buy.
How to pick parts
- Find the frame name printed or molded on your frame.
- Use the table to find the matching size, then look for slides, barrels and lower parts kits listed for that size and generation.
- Caliber and generation matter. Confirm both in the listing before you order.
- Browse our shop and filter by the model name.
