Taurus Revolver
Looking very nice Howl, metal textures are delicious!
Some good ol' CC:
- For the hand grip - I would switch to smooth shading to hide the low polycount - currently you can very clearly see the edges/polys.
- The metal screw just above the trigger looks a bit flat and/or could use a slightly different texture or colour (for added realism).
- The bevel border of the metal frame looks a bit too chunky, on the real thing the bevel is very smooth:

Glad to see you're going to try and get it in-game. I know doing the config and texture conversion is a pretty boring task, but it's also a really important one - what you see in your render might look very different when inside Arma's engine.
Other than that, I like it
