Glock 42/43 Fixed Rear Sight Features The Glock Fixed Rear Sight 6.1 is manufactured to the same specifications as the sight that comes standard on the Glock 42 and Glock 43 from the factory. Its white stripe configuration gives a clear high contrast reference point that helps shooters acquire the sight picture quickly in both range and defensive scenarios. Because it is a factory Glock part installation requires no modification to the slide and the fit is precise right out of the package. This makes it an easy way to restore a pistol to its original configuration after wear or damage. Built from a durable black polymer this rear sight is lightweight while still holding up to the recoil impulse of repeated firing. It is a standard fixed sight rather than an adjustable unit keeping the simple low profile design Glock pistols are known for. Owners of the Glock 42 or Glock 43 who need a replacement part can count on this sight dropping straight into place. It is a practical affordable way to keep a carry or range pistol in top working condition.
