Francisco, you will need a shorter profile HP design such as the Sig V-Crown : https://www.budsgunshop.com/product_info.php/products_id/108721/sig%2bsauer%2be9mma150%2belite%2bv-crown%2b9mm%2b115%2bgr%2bjacketed%2bhollow%2bpoint%2b%28jhp%29%2b50%2bbx%2f%2b20%2bcs

Francisco, this seems to be an ongoing problem with these guns. You just have to experiment with different ammo, stay away from hollow points, a steep feed ramp prevents the MP40 from feeding hollow points. Good luck!
