Click-adjustments are positive and precise, allowing for reliable and consistent point of impact changes. This Kensight Rear Sight is equipped with a Fully Serrated Slanted Blade that reduces glare and offers a simple, defined sight picture that helps a shooter to maintain focus on the front sight post. This rear sight fits the popular Novak LoMount rear sight dovetail cut, often found on many factory-produced and custom 1911 pistols. Notes:Sight Dovetail: Novak LoMount (65 Degree x 0.495")
