Easy really depends, getting an animation to look realistic and smooth is probably one of the harder things to make, as for example, if I wanted to animate a character moving his arm it would involve almost all parts of the body moving as well, so to make a complete, again, for example, a walking animation you would have to involve the entire character moving to make it realistic.
Obviously with gun models it's only a gun and an arm and a hand, so that limits it down a little bit which makes it a bit easier, but still, if you want to animate just one finger probably almost all parts of the hand and the arm would be moving ever so slightly to make it looks realistic.
I've seen a lot of game projects where people will, for example, animate a walk sequence and they have JUST made the legs move and the entire torso stationary, and it just looks like some sort of strange robot (Although robots would also demand to move a lot of pieces of the body to move when they would walk) that's like gliding a cross the floor.
Although I've never animated anything in my life (Need to learn) so it might be quite easy with guns.
I just know it's kind of a pain getting a animation look realistic.
