Thanks for the thoughtful reply.

I’ve heard many times that revolvers or semi-auto have less recoil than the other, hence the question about slide mass/energy, as the only element I could see being different which could possibly explain why people hold this opinion.

Do you know of any actual metrics/tests done that show this clearly? Or is it just a perception issue?

(And yea, we’d have to agree on a definition of what we’re measuring/comparing). Do any gun magazines run proper tests occasionally to make comparisons?

I admit my physics classes were a long time ago, but at first glance it seems felt recoil would only be marginally different between a revolver and a pistol using the same round. If anything, I’d expect the revolver to have a greater felt recoil, given the mechanics of a pistol… But I could very well be wrong.
