I recently handled an all-tan factory Vickers RTF2 G19 that had a Vickers u-notch rear sight and a green outlined tritium front sight as part of the package. The front sight was marked Ameriglo. I instantly fell in love with that sight combo. I couldn't explain why exactly, but I picked up that front sight much faster than the Trijicon HDs and Ameriglo Spartans I have been using for the last several years, so I'm now trying to replicate that combo on my own Glocks.

According to Wilson's site, the Vickers Elite Battlesight requires a 0.245” tall front post. However, according to Ameriglo's site, the closest Pro-Glo front they offer to that is 0.240" tall. I'm no expert, but five thousandths seems like a fairly insignificant difference... perhaps imperceptible. So, I'm not sure if the gun I handled had that slight mismatch from the factory, or maybe Ameriglo partnered with Wilson for a special run the correct height, but all I need to know is if this slight discrepancy will mess up my POA/POI to a significant degree or not, or if this combination will be perfectly acceptable.

Photos from GunBroker below show the combination I'm speaking of. I appreciate any advice.

Up close, not enough to worry about. You will probably notice it at 50-100 yards.

I called Wilson and they said the -0.005" height would definitely not be an issue and in fact would be ideal for the shorter sight radius on a G19 since these numbers were published with a G17 in mind, but CS said the width likely would be a problem. They recommend .125” wide front sights for the Vicker's rear battlesight, and the Ameriglo is .140" wide, a discrepancy of +0.015" - in conjunction with the shorter sight radius, it would would likely fill up the notch entirely.

I emailed Ameriglo about this also to see if they could tell me if the front sight on the Vickers G19 is proprietary or not. It'll be interesting to see what their CS has to say, but it's starting to sound like Ameriglo may have made a special run of Pro-Glo sights specifically for this collaboration with Wilson for the Vickers Glock.

Response from AmeriGlo in case anyone cares:

What is the sight radius?
