No issues. 10000% better than the factory grip module.
The first few times its a PITA but gets easier over time. I had to use a flathead under the front to pry mine out for a few cleanings.I ordered the Wilson Combat module and received on Saturday, 28 January. The chassis was not quit as easy to take out of the M18 and install, but I got it done. The grip is a big improvement over the standard grip. The texture is more aggressive and more positive. I plan on getting to the range this week to try it out.
Thanks for the suggestions.
