Glock ATS Sight:

Designed for speed, precision, and clarity of sight picture, our one-sight-fits-all Glock pistol sight kit includes:

• 5 differently colored front sights
• 5 differently colored rear sight inserts
• .044" of elevation shim
  (pink = .015", clear = .008", tan = .004", red = .002")
• Front sight tool and rear sight set screw hex key

With .45 and .357 Sig., start with .004" of shim. With 9mm and 40 cal. start with .020" of shim. Amount of needed shim will vary, depending on load and particular barrel. Approximately, each increment of .002" to .0025" of elevation shim will affect bullet impact by 1" at 25 yards. With the tools provided with each sight kit, most will be able to install our Glock sights without professional help.
