US12392580 - Fiber optic handgun sight

A firearm sight has a body having an attachment facility configured to connect to a pistol having a forward target end and a rear end. The body has a forward end and an opposed rear end associated with the forward and rear ends of the firearm. The body defines a bore with a forward opening and a rear opening. An elongated insert is received in the bore and has a rear end and a forward end. The insert and body have an insertion limiting facility configured to admit insertion of the insert with the rear end of the insert inserted via the forward opening of the bore, and to prevent passage of the insert beyond a limited insertion amount. The insertion limiting facility may include the bore defining a step, a greater bore width forward of the step and lesser bore width rear of the step.
