NOVAK'S® "EXTREME DUTY" SIGHT
ADJUSTABLE SIGHT FOR AUTOMATIC PISTOLS
New from NOVAK'S®! For 25 years, the name NOVAK'S® has been associated with the very best in custom pistolsmithing. That even includes prototype and design specifications for major manufacturers like Smith & Wesson. But most shooters know NOVAK'S® for the fixed sight system most commonly specified for installation on custom pistols. NOVAK'S® fixed sights are standard as original equipment on many of the best makes and models sold in America - Springfield, Smith & Wesson, Colt, etc. The Lo Mount NOVAK® system is on the pistols used by the elite FBI HRT and SWAT teams, as well as the Texas Rangers. Often imitated but never equaled, NOVAK® sights are the world's standard of excellence. NOVAK'S® now takes excellence in sight design and manufacture to new heights.
NOVAK'S® introduces it's "EXTREME DUTY" line of FULLY ADJUSTABLE rear sights with the snag-free contours that made the fixed-sight system a necessity on pistols carried by professionals worldwide. Now it is possible to precisely adjust your NOVAK'S® sight system with a screwdriver to deliver point-of-aim, point-of-impact performance with any load or bullet weight. Such convenience has never before been available in a practical, real-world, no-snag rear sight system. NOVAK'S® adjustable rear sights are available with options like the highly regarded Trijicon tritium insert night sights.
PLEASE NOTE: Because NOVAK'S® "EXTREME DUTY" ADJSUTBLE SIGHTS do sit higher on the slide than standard sights you may need to replace you front sight. If your pistol currently shoots 4" or more low, you should not have to change the front sight. If you pistol currently shoots on target, we recommend changing to a higher front sight.
