I think if I was in Iraq and wanted a sidearms sent to me from home, I'd ask for a 3" or 4" S&W 686-3 loaded up with .357MAG semi-wads. Can't ask for more where stopping unarmored badguys is concerned IMHO 
Yes, mag changes wouldn;t be as easy, etc. - but I'd only be using it to fight my way back to the M4 I never should have set down in the first place
