I've been trying like an mad man to get the grip stripe thingies on the back of the slide to look good with booleans, but to no luck.. so I booleaned out the entire area where the grooves are and then created the grip thingies from separate cubes..

probably not the best way to do it, but that was the technique that got me closest to what the actual gun looks like..





think I'm gonna call the barrel done (at least for now) and start working on the rest of the gun..
