Most of us are accustomed to a tight fitting rear sight that is drift-adjustable. The the rear sight slips loosely into the rear dovetail, which is unsettling to old guys like me. It allows me to make hits fast and accurate out to 25 yards with a 26.

So, I run the XS because the large front glows bight in both daytime and Darkness. If you have trouble seeing the front sight, the XS sights might help. I can tell you that I prefer the XS Sights over the Ameriglo Agent sights.

The link above is for the 9mm, but they are available for the 30. I checked their website, they make sights for almost every Glock model except the 30. My newest favorite are Night Fision, but unfortunately they don't make a sight for the Glock 30. I've installed only 3 or 4 Tru Glo Pro's and they seemed to be decently manufactured, so those may be a good option for your Glock 30 if you don't want to spend the money on Trijicon. Took a look at the sight channel of the aftermarket slide under magnification, it was the slide that was poorly machined. I did have someone bring in one of those Hi-Speed Low Drag type race gun slides for a Glock 17 that I had issues installing Trijicon sights, but it wasn't the fault of Trijicon. As a dept Armorer, I've seen and installed more than I can remember and haven't seen or experienced any issues with the sights. Had an offspec M&P Shield rear sight that I could push through the rear sight channel with a finger, then a USP front sight that broke when being installed with an MGW sight tool by an Armorer.

I used to be a Meprolight fan until recently.
