How do you assembly a beretta 948 pistol?

Beretta 948

Hi. Take out the mag, put on the safety and lock the slide open. From the front of the bbl, push the bbl straight back toward the rear. You may have to "help" it with a mallet. Lift out the bbl from the rear through the top of the slide. Release the safety and just run the slide forward and off. You can do it!
