O.K., I'm a sixgunner, not really a pistol shooter. I'm not sensitive to recoil, I shoot heavy .45 Colt and .44 Magnum loads regularly. Having said that, here are my observations when shooting auto pistols:
Shooting the Browning-type short recoil pistols, I feel three recoil impulses: First the firing of the cartridge. Second, while the pistol is arcing up in recoil, I feel the slide hit the stop, which adds a little impetus to upward travel. Then I fell the slide stop as its forward motion is arrested.
With the toggle-link design of the Luger, I don't feel the last impulse, termination of forward movement.
With rotary bolt pistols, I feel only the recoil of the cartridge, but am aware of mechanical "goings on" as the pistol cycles.
Straight blow-back pistols don't usually give me any recoil impression except for the firing of the cartridge.
Do I feel these because I'm used to the one impulse of the revolver? Or do ya'll feel these miniature "jolts" too? Or is it just a part of shooting the pistol you've become accustomed to, and no longer notice?
