The issue is most people here assume that firearms are far more powerful and difficult to handle than they really are. Most weapons, especially more modern ones, are very manageable in regards to recoil, especially considering most are fired in short bursts or even single shots.
For example, I remember having a particularly amusing conversation with someone a while back when I wanted to start giving Delta (T:RP's medical division) shortened shotguns rather than full sized rifles. They thought that shotguns were some sort of handcannon that would launch unskilled users across the room hollywood style. It's something which bothers me quite a bit at times. You would think in an FPS based roleplaying community, with all the settings including a large amount of combat, that people would take the effort to do at least some light research into what they are roleplaying.
