Well priced hk suppressor height sights for the price, but may need a little bit of fitting - XS Sight Systems R3D Night Sights for HK VP9 OR Supressor

I was looking for some tall night sights to co-witness on my Holoson 407k. The XS Sights are probably the best priced on the market. I've probably done half a dozen sight installs for various Glock pistols, but this was my first experience trying an HK.

I did the install using an ATG pistol sight pusher. I made my zero marks on the slide using the stock sights and a white oil market. Getting the stock rear and front sights off the gun was easy.

Next I installed the front sight, and moved it until the orange dot was exactly above my white mark I made on the slide. It went on very easy.

The rear sight was a bit tougher. When I was pushing the sight onto the slide I noticed a lot of resistance, so I looked very closely under my jeweler loupe and I could see a very small amount of material was being sheered off the back of the rear sight fitting. So I pushed the sight off and using my dremel, I began to polish the rear side of the fitting, removing very little material, mostly just smoothing it out.

I tried pushing the sight onto the slide again, and this time it went on with much less force needed, and still was a very snug fit. Overall I'm very satisfied with the install, but keep in mind, don't force it. If you feel more resistance than you're used to, take a close look and see if you may need to polish the rear sight fitting a little bit before install.
