Considerations & Trade-offs

  • This hammer extension is specific to the firearms it fits, so compatibility needs to be checked carefully before purchase or installation.
  • It is designed to add a horizontal extension to the hammer, which changes the firearm’s profile and may not suit users who prefer the original hammer configuration.
  • The product is described as especially useful on scoped firearms where clearance can become an issue, so its value is most relevant in that setup rather than on all rifles or shotguns.
  • It can be mounted on either the right or left side, but the best orientation will depend on the firearm and the user’s preference.
