Once upon a time , a Smith and Wesson engineer discovered a little known equation dating back to Leonardo Da Vinci's time which established that the longer a gun's trigger guard was, the more accurate the piece would be.Then one day someone found out the legend was bunk and rather than admit that-which would hurt sales-the errant employee was quietly dismissed, and the trigger guards were switched to the curved variant under the cover of night.

Or so the legend goes, in any case.


In real life, the difference is just appearance.
