- Single-spring package means there is no spare included for backup or future use.
- This is a mainspring only, so it addresses one specific revolver component rather than a broader tune-up or parts set.
- The description indicates it duplicates the factory spring's rate, so it is intended as a like-for-like replacement rather than a performance change.
- Fit is limited to S&W K, L, and N frame revolvers, so compatibility should be confirmed before purchase.
