Truth; I have owned both. I was surprised at the amount of recoil from the Mini-14 - it was comparable to my Winchester 30-30. With pistols, my little Bersa 383A .380 had about the same felt recoil as my 9mm Ruger P95. The single-stack Bersa had a much thinner grip than the massively wide Ruger, which concentrated the felt recoil into a smaller area; the 9mm has a heavier slide to move back; and the Ruger has a polymer frame as opposed to steel.
I've never had the opportunity to shoot a .40, and the one time I had a chance to shoot a .45 I was 11 and too scared of it.
