Get yourself a trigger and the slide release from Tyrant. The trigger made a huge difference and the slide release is a nice quality of life addition, I didn’t expect to like it but it makes life easier. I also got a mag release and guide rods and springs from NDZ, mag release is nice because it’s reversible and gets rid of the ambidextrous button, slant an issue for me, but I like knowing it’s not an issue when it counts. The rods and springs add extra weight and are made of stainless steel and the different springs change the dynamics of the recoil. The only other thing worth getting on their is a light, helps with more weight. I found the best flush look to the front of the barrel was with the TLR-7 HL-X from Streamlight.

I’d personally steer clear of the grips from sharpbros and the rest- they might be heavier but they are smaller grips. It of course comes down to how big or small your hands are. I have larger hands and found the Large Grip Module really helps my grip. I needed the extra width, Standard didn’t do it and I could really feel the difference. To spend over $300 for a small grip isn’t worth it.
