BIG SIGHT GAUGE
BIG SIGHT GAUGE
The sight gauge enables the shooter to adjust for pistol model number or barrel length and then rotate the front and rear sight dials to quickly find the ideal combination. Once the sight sizes are determined, the shooter can place these sizes on their pistol.
The Sight Gauge is available for use at any dealer that carries BigSights.
The Sight Configurator is an online interactive tool that enables shooters to set the pistol model or barrel length and then obtain an arm’s length perspective view of the sight picture for all front and rear sight combinations. Find your Glock model in the links below or use the drop down menu under the Sight Configurator tab on the top of each page.

BIG SIGHT SIZE COMBINATIONS AND SIZING EXPLAINED
The grid below is a simulated perspective view of all sight size combinations on a Glock 17 held at arm’s length. Please note that pistols with a shorter sight radius than Glock 17 will have a slightly tighter sight gap than the images shown below. Glock models with a longer sight radius than Glock 17 will have a slightly larger gap than the images shown below. Please CONTACT BigSights with any questions on sight sizes or for support.
There are four front sight sizes and four rear sight sizes making sixteen possible combinations. The combinations allow the shooter to create a custom sight picture based on width as well as the tightness of the front sight post in the rear sight notch
All front and rear sight posts are the same height
The difference in size between the front sights is the width of the front sight post – F1 is the most narrow post and F4 is the most wide
The difference in size between the rear sights is the width of the rear sight notch – R1 is the most narrow notch and R4 is the most wide
Guarantee: If for any reason, you are not completely satisfied with your sight picture, your sight/s can be exchanged for a different size or returned for a full refund within 30 days of purchase.
