I have both Beretta 84 and 85. I have a Glock17 to compare as well as several other .380s and 9mms. Either Beretta is a very easy firearm to shoot IMHO because of the ergonomic design. It fits and feels exactly as a pistol this size should feel. Can you feel recoil...Yes. Is it harsh ...No. Comparing to a 9mm, I would say the Berettas are lighter in felt recoil. The only factor in making the Glock a bit more controlable is it's size.
Compared to a PPK, which I no longer have, but based on my memory, I would call the Beretta easier on the hand, less snappy. I'd take the Beretta over a PPK.
My favorite .380 is the Sig P232, which I seem to be able to shoot a little better than my Berettas. Even though the Sig is about 6 ounces lighter, it feels the same in my hand recoil wise.
In comparing the Berettas, there is a definite difference between the 85 which has a single stack, 8 round, slim grip and the double stack, 13 round grip of the 84. This may make a big difference especially if you have smaller hands.
Compared to the CZ 83 or 82, the Beretta 84 is very close in size, weight and capacity, (again the Beretta 85 grip is thinner), however the quality of the Beretta is decernably higher. The Berettas have proven to be remarkably reliable. Neither of mine have ever failed...period. Both of my CZs have. Recoil comparison between Beretta and CZ is indistiquishable. FWIW.
In all fairness I should mention that I'm not really a Glock fan. They make excellent firearms...I just don't prefer them to my favorites.
