Bersa offers walnut replacement grips for the Thunder 380/22. These grips are very nice and easy to install. There are two points I want to make about these grips. They greatly increase the thickness of the grip. This is a good thing or a bad thing. For me it was not good, so I am returning them. What I love about the bersa thunder is that the grips fit perfectly in my hand and I have small hands for a guy. But many of you out there purchased these guns for your wives/girlfriends and you wont use it because it is too small. These grips add a nice amount to the girth of the grip and should make it more comfortable for those with larger hands. I am planning on writing an article on this with exact measurements, so stay tuned.
