I don't shoot handguns much but when I went today I noticed after a few dozen rounds I got the "pump" feeling in my forearms, like if I was working out or something? Does anyone else get this feeling from shooting alot?

Shooting a handgun is basically an isometric exercise. One arm is pulling against the other, trying to control recoil...all while holding a two pound hunk of metal 3' away from your body.

That's why you see weaker individuals leaning back to compensate and balance.

No, at least I don't. As you say you don't shoot often so the action is unusual for you and the muscles used not familiar to it. Shoot more often and likely the sense of a "pump" will not happen again.

You might be over gripping the gun and inducing premature muscle fatigue, avoid the push/pull tension and practice holding the gun up for shorter periods
