Is it possible to disable the movement of the sprite when a new weapon is acquired (changed)?

I am currently trying to create a game with simple content like Wolfenstein 3D.

eFPSe weapon HUD icons are too small, so I am trying to add larger HUD images to the weapon sprites, but the movement of the weapon when you get it (or take it out) makes it unnatural.

(I was able to disable the weapon movement while walking by rewriting the "Player.dat" file. Perhaps the movement when the weapon is retrieved could be rewritten in the same way).
