The Heckler & Koch H&K VP9 OR SLIDE W/TALL ST SLIDE CP Made a Bold First Impression

The Heckler & Koch H&K VP9 OR SLIDE W/TALL ST SLIDE CP is a drop-in replacement slide designed to upgrade your existing VP9 pistol. Specifically, it adds optic readiness and taller sights, something many VP9 owners, myself included, have been clamoring for. I was excited to get my hands on this, as I’ve been a huge fan of the VP9 platform for years, but always felt it was missing the optic-ready capability that many other modern pistols now feature.

I’ve always appreciated the ergonomics and reliability of my VP9, but I’m now at the age where iron sights are becoming a little harder to use effectively. The thought of mounting a red dot was incredibly appealing. Several companies offer slide milling services, but the factory option from Heckler & Koch seemed the most reliable and easiest path to take.

Unboxing the slide was straightforward. The slide arrived well-packaged and the finish looked flawless, matching the original finish of my VP9 perfectly. The included taller, suppressor-height sights were a welcome addition, already installed and ready to co-witness with most popular red dot optics.

I considered having my original slide milled by a third party, and I also looked at complete aftermarket slides from other manufacturers. Ultimately, I chose the Heckler & Koch option because I trusted the factory tolerances and the guarantee that it would function perfectly with my existing VP9 frame and internals. The factory option was also surprisingly cost-competitive. My initial impression was excitement. It felt like Heckler & Koch finally delivered exactly what the VP9 community had been wanting.
