yeah the colt trigger is an odd one isn't it... isn't a hair trigger like most handguns. The same goes for the Dosdievski, they're sliding triggers ... so they generally look more part of the gun.
When developing weapons its good to keep in mind that alot of parts may not move or animate in anyway - so the idea is to make the general outline and then just develop the mesh to accentuate any Texture details you give them
This is oftenly done through setting up accurate Smooth Groups rather than leaving all of the blending to the texture - also detail that doesn't need to be there, you don't make it...
suchas if there is a switch on the side, rather than making the whole switch and making it rounded with a pertruding part - make a simple box perhaps with a tapered end and let the texture handle the detail.
and even then certain detail can be left off all together even major detail and left to the texture depending on how close the weapon will be seen
