I also strongly recommend the Alien Gear Shape shift system. I agree with everything you stated, and I also want to ad this: You can add-on to the system for multiple guns. I own multiple carry weapons and this system allows me to quickly (less than 60 seconds) change out the “shell” from one gun to another. It’s deceptively simple once you get over all the stuff that comes in the box. I watched the recommended YouTube video that came with it and was instantly put at ease.
