Considerations & Trade-offs
- Designed for P220 and 1911 .45ACP models only, so fitment should be confirmed before purchase.
- Its role is protective rather than functional, so it is meant to cover the threaded barrel end when a suppressor is not installed.
- The black finish and knurled surface add grip and a low-profile look, but the product is still a simple thread cap rather than a more elaborate accessory.
