Congrats on the G2. I bought one for my mom and liked it so much I got one for me. I was pleasantly surprised with how accurate it is. Unfortunately, there are no accessories or aftermarket items that I know of for the G2. I looked at the Advantage sights, but I think they are rather expensive for a standard sight. If they offered night sight, I'd try a set. Mine is for daily concealed carry so I have no need for a laser or light, but it's nice to have the rail just in case. You never know. One thing I did learn is that 24/7 and standard PT111 mags fit the G2. It's cool to know you can pop a 17 rounder in the G2 if needed!
