i wonder how effective some CO2 airgun that shoots steel pellets would be.

No idea how illegal it would be to carry one around. Also no idea how likely is it to get shot with an actual firearm in europe in case you ever needed to get that thing out of your bag.

In my mind someone pulling out a gun that looks like the real deal would be enough to make any sane person to run. For the less sane i'd hope getting hit by ~100m/s 4.5mm steel ball would hurt enough.

I also found out that there are airgun pellets with fucking explosive tips
