The arms holding the weapon are at far off the body at the beginning. They return to their correct position after you are up on your feet again.
Happens often.

Same bug as switching players to view in spectator mode.
simply due to the way First Person models are handled and the fact that they try and smoothly place you back into your body.
Personally I don’t think a “fix” is the right thing to do but maybe make the arms invisible until you “lock into position” and then show a pick up animation for half a second. specially since during this animation you cannot shoot anyway it would not “nerf” anything but it would remove the jarring effect
