The texture definition and material look great overall. One thing I noticed are some sharp edges / normal map errors. You can clearly see a seam right over the slide grip / grooves. Also, the edge wear in some parts like the lower part of the handle looks a bit too generic and evenly spread. I'd try to make all the edge wear on the gun a bit less heavy and the grunge overall less generic, adding grunge and scratches only where it would make sense, instead of all over the gun.
The edge wear created by the generator in substance is very visible, it looks unnatural. I think you can push the textures more to achieve a better look.
