Product Description

'80 Series Colt® 1911A1 TENON STAKED PATRIDGE FRONT -.150" TALL (KENSIGHT ITEM #870-112)

The M1911-A1 Series 80 tritium front night sight is a direct replacement for the Colt Series '80 Gold Cup Pistol with a fixed MIL-SPEC rear. 

This sight is what is called a patridge style blade.  It is ideal for target shooting because the rear of the blade is completely vertical.  With the addition of a serrated blade, this gives the shooter a better sight picture because there is virtually no glare from the sun, as well as a good contrast between it and the rear sight.  At just .150" tall, this sight was made to pair with Kensight® item 860-202 but will work well with any standard fixed MIL-SPEC .330" wide x .115" deep rear sight. 

The blade dimensions are .150" tall x .118" wide and has a .125" tenon to fit a '80 Series Colt.  The green tritium insert is made and installed by Cammenga®, is .077" in diameter and has a bright white outline made of PVC.
