Your uvmapping is still really irking me. I just noticed the inside of the barrel is mapped with the same texel density as the back of the slide. Also you have a lot of weird scribbly looking details on the spec that look like they were just quickly drawn with a basic Photoshop brush and not touched afterwards.
Why are both sides of the trigger guard/magazine/hammer/grip safety/etc. uvmapped separately? They're completely symmetrical! You (or whoever unwrapped it) is wasting a shit ton of UV space and making a lot more work for you, the texturer, and also missing out on having everything look higher res due to making better use…
