Key Rifle Differences Summarized:
Aesthetics and Construction: Hawken is the most ornate with traditional brass hardware, Seneca is simpler and lighter, while Renegade is utilitarian, focusing on durability and performance.

- Barrel Length: Not explicitly stated, but commonly associated with having a shorter barrel, typical of pistols.
- Ignition: Percussion cap.
- Stock: The stock has been noted to have a weak spot in the wrist area, which can be prone to breakage. It's advised to use a load stand that supports the wrist during loading to mitigate this issue.
Load Specifications:
- Projectile: Home cast .445 pure lead balls.
- Patch: OC Daisy patches .015 thick.
- Powder Charge: 30 grains of Swiss 2F black powder.
Accuracy:
- Described as very accurate with the mentioned load specifications. Users have reported enjoying shooting it and finding it fun to use.
Legal Considerations:
- The Patriot Pistol was part of a notable Supreme Court case, United States v. Thompson/Center Arms Co., where it was determined that the rifle conversion kit for the pistol did not constitute a short-barreled rifle under the National Firearms Act of 1934, even if the pistol could be fitted with a shoulder stock.
- Discontinuation: The Patriot Pistol was discontinued following a major factory fire in 1996 that destroyed all tooling and parts for this model.
