No-Snag Shape, Low Light Visibility
Competition plain, target-style, undercut blade with protected notch. Hangs over the rear of the slide and extends sight radius for quicker, more precise sighting. Lo-Mount has an angled top surface with mitered edges that won’t snag on holsters or clothes. Rebated blade fights glare. Wide Notch (WN) has enlarged , .140" notch to provide more light around the front sight for a clearer sight picture and faster target acquisition. Helps aging eyes see front sight more easily.
Browning Hi Power models fit the Mark II models.
