I installed some VZ black checkered grips and the Yankee hooked grip extension and went to the range. What a difference! I shot two handed and single handed and the R9 felt very tame compared to the stock configuration. Before, I had to constantly adjust my grip, or 're-grip', or grip the R9 like a vise before the shot. Not fun. The stock grips are slippery, as you know, and to me, it felt like it wanted to jump out of my hand with every shot. The 'hooked' grip extension is a real confidence builder, and the R9 is not going anywhere when flipping its angry little head... That "hook" kept it in place and there's no feeling the need to re-grip for better control. Awesome. The checkered VZ grips are, let's say, 'grippy', so that in conjunction with the anti-flip hooked extension, the results were impressive. I actually enjoyed shooting the little lightweight powerhouse and now feel very confident I can handle any off-handed weird grip-of-the-moment situation I might encounter.
