Manufacturer documented

Based on manufacturer documentation or support information.

Requires a THREADED BARREL in 1/2x28. Most of these pistols do not ship with one — check your barrel before buying. ⚠️ THE PDP STEEL FRAME IS DELIBERATELY EXCLUDED FROM hostsNamed: PMM lists it as fitting ONLY with a PMM proprietary threaded barrel, so the pistol alone is not sufficient and a plain fitment row would overclaim. "NOT COMPATIBLE with: Non-PDP Series Pistols." Adds approximately 1 inch to overall length — a holster consideration. Same ammo exclusions as the 509 comps.

Check your exact model and part before ordering. Fitment limits
