Great product - Align Tactical Thumb Rest Heckler & Koch VP9 Takedown Lever

Super easy install first off. I’m gonna start with the downsides. It makes field stripping harder due to the lever being much stiffer. That’s pretty much the only downside. Gives great leverage during fire, feels natural if you’re using a “Stoeger” style of grip. If you have big thumbs you could run into a lot of slide contact so that will require further training with the add-on. Texturing on the pad is great and it feels solid.
