Can you explain to me why this is? Is it the grains in the powder?

I am so silly that I though recoil was proportional to the amount of gunpowder one could pack into a cartridge case, and the weight of the bullet to be launched. Go figure...

Also the weight of the gun and comfort of the grip. I think what is happening here's an example of comparing apples to oranges, (Comparing a lightweight .40 with a short grip, to heavier .45 with a larger grip frame, like a 1911 type).

Has anyone mentioned the weight of the firearm yet?

[Brennan16]

Sorry 75370. You beat me to the punch. That should have been the first thing that was said.
I have a 5906 that doesn't recoil hardly at all yet my PT111 rises and flips and kicks pretty heavily.

The .40 has noticeably more recoil than a 9mm IMO. Both operate at the same pressures if I'm not mistaken, but you push a bigger chunk of lead out of the .40. Also .40 generally operates about 14,000psi higher than a .45.

Thank you.

You have to consider that the 23 has a shorter barrel than the 21 so the snappyness would make sense

HAHAHA this is my kind of thread as I am a recoil junkie. I feel the .40 is snappy compared to 9mm/.40/.45 in a pistol, it just wants to lift the muzzle up more for me. The 9mm is going to be the lightest of the felt recoils, then the .40 but the snap is a down side for many, then the .45 which hits hard but the recoil is very easily managed so second shot on target is easily very quick. The .45 gives you the percussion that you can feel deep down in your bones and a ear to ear grin that you just can't knock off with a sledge hammer.

All of this can be changed if you play with the barrel length or type of gun used or even the ammo used, but if you fire all of these out of relatively the same style gun with the same barrel length and somewhat similar ammo you should see what I am saying.
