With a weakening grip from arthritis, I would think pulling the lever would be easier than pushing however, OLETYMER, and BROWNING BOY ,both of you certainly should be able to talk from experience. Pumps were all I shot 25 years back when I stopped shooting.
Of all the Perazzi's I have owned , I still think is it is a hassle to push the lever because of the long throw. But it is much nicer on the Krieghoff since the lever throw is much shorter. What is really nice is the Ljutic, Bowen and Seitz plus Alfermann for us lefties. Bill Cole can change his to left hand opening, he did it for me to try. I liked it much better. I shoot all field guns the way they come with no problem.Not much choice there. I asked Bonillas about the Perazzi and he said it could not be done. It can be done, they just don't want to fool with it. Krieghoff built a left hand opening top lever some year's back for a skeet shooter. I would like to know if they can set that up now.
