M100 would be the one...but only if it gives you an FPS under 350.
For a gun to be effective outdoors, however, it does not need to have a higher FPS. You can have a gun shooting 320 FPS and still be more accurate and longer range than most guns shooting 400 FPS. In this case, having a good hop-up is very important.
