Just as a point of reference, Recoil Factor:
Add Velocity to Bullet Weight and multiply that number by the Velocity. Then divide that answer by the weight, in pounds, of the firearm multiplied by 80. Then divide that number by 100.
For example, my S & W 500 PC Hunter, 10 ½ inch barrel, with Cor-Bon 350gr JHP moving at 1600fps would be, using the listed weight of 82oz [5.13 lbs] equal to a Recoil factor is 76.10. Muzzle energy is 1990 foot pounds.
My Seecamp .32, with Winchester .32 60gr Silvertip Hollow Point moving at 970fps, using the listed weight, with magazine, of 13.65 oz [.85 lbs] is equal to a Recoil Factor of 146.39. Muzzle energy is 125 foot pounds.
While my Seecamp .380, with Winchester .380 85gr Silvertip Hollow Point moving at 1000fps, using the listed weight, with magazine, of 13.65oz [.85 lbs] is equal to a Recoil Factor of 158.97. Muzzle energy is 189 foot pounds.
And my Kel-Tec P-3AT, with Winchester .380 85gr Silvertip Hollow Point moving at 1000 fps, using the listed weight, with magazine, of 11.10oz [.69 lbs] is equal to a Recoil Factor of 195.50. Muzzle energy is 189 foot pounds.
And now for my Rohrbaugh R9s, with Winchester 9mm 115gr Silvertip Hollow Point moving at 1225 fps, using the listed weight, with magazine, of 14.3oz [.89 lbs] is equal to a Recoil Factor of 230.55. Muzzle energy is 383 foot pounds.
And least we forget my S & W 360PD, with Cor-Bon .357 140gr JHP moving at 1500fps would be, using the listed weight of 12oz [.75 lbs] equal to a Recoil Factor of 312! Muzzle energy is 525 foot pounds.
Many folks consider a Recoil Factor over 100 to be unpleasant; certainly anything over 200 is very unpleasant. 312?, well there you have it folks, painful. You pays your money and takes your chances. Double tap? Sure, but you have to practice!
I have the 360PD, and like it. I would not trade it off, but it is not a pleasant gun. It has a job and it does it REAL well. If it is not for you there are a lot of milder shooting guns out there. Just a warning, this is not a 9mm target pistol. It is an honest to God concealed weapon designed to take a .357 Mag and protect a person. If you can deal with that it may be right up your alley, but don’t try to fool yourself into feeling Macho! It is not about that.
