Hey, guys - - Let's all back off just a bit, huh?
One thing upon which we should ALL be able to agree: handgun recoil in "normal size" firearms is EXTREMELY subjective. In a .454 or a .500 S&W, yeah - - EVERYONE can agree there is very substantial recoil.
But, as to comparing a .380 to a .357 for recoil, well, it's all in how the individual perceives the physical sensation. You simply can't correct another person and say, "No, you
do not feel what you say you're feeling." Makes no sense, and it can be considered offensive.
Besides, there are .357s, and there are other .357s. Take, for instance, an S&W Model 27 with 3-1/2 inch barrel, weighing 42.5 ounces, with aftermarket oversize rubber stocks, firing low-end factory magnum ammo. Most of us, especially revolver shooters of long experience, would think this combo pretty soft in the recoil department. It might be noisy, but certainly not painful. The same experienced shooters would probably agree that a wood handled two-inch Airweight, loaded with +P 158 gr .38 Special ammo, is very vigoous, even painful, to shoot.
There are some objective factors , though. Take two near identical handguns,differing only in frame construction, with identical stocks, loaded with identical ammo, and the comparison
can be right on point. Colt Detective Special vs. Cobra. S&W Model 10 M&P vs. Model 12, or Models 36 vs. 37. (The REAL)Colt Commander .45 vs. Combat Commander (all steel) .45.
Yes, this is the Semiauto forum, and this revolver comparison is getting a bit off topic.
Back to the subjective side. A great many veteran shooters with a lot of varied experience agree that .380 pistols of certain designs have a great deal more felt recoil than others. The Beretta 1934. The AMT Backup (the original single action design.) The Walther PPK. These are all of unlocked blowback design, and there's something about the backstrap angle and width thereof that enhances felt recoil.
There have been comments above concerning the apparent recoil of the Kel Tec P3AT pistol. A side-by-side comparison of this pistol, with its locked breech, with the '34 Beretta, weighing twice as much, is revealing.
TO ME, the Beretta has substantially more felt recoil. Your perceptions, of course, may vary.
Best,
Johnny
