Unless you have developed proper grip, yeah, it may even jump out of your hands when firing more powerful cartidge. In my expirience, and I didn't have pleasure to shoot much, 9mm is very pleasant cartridge, thou pistols are hard for newbie to get nice groupings from. I think it was one of CZs, I don't remember which one. And then I shot rifle, AK to be exact. It was quite long time ago, so your milage may vary from mine. You may think your shoulder may hurt after firing something with that big caliber. False, AK does not kick in shoulder, unless you don't have stock pressed against you. And then there is upward recoil, which at that time was gigantic for me. Thou it was a good while ago. Need to bug my friend to take me with him to firing range next time. BB guns are not enough. Even ones with blowback.
