So I have a G20 Gen 4 that I would like to do a sight upgrade on.
I have a spare TTI .235 x .115 fiber optic front sight and just needed the rear, so I ordered a Dawson .270 x .135
The Glock plastic sights are right on at 50 feet, so I measured everything.
.190 rear and .155 front
The math looks good from Glock to Dawson. About a .035 differential.
The Dawson/TTI combo should work.
The only dumb thing that I ever found with Glock is that they seem to describe their rear sight heights including the depth of the dovetail.
C'mon Glock, this stuff is confusing enough.
The depth of the dovetail is about .080
Here's a useful chart when working with Glock sights...
