I’ve owned a Benelli M1 for a long time and recently purchased a Beretta 1301. Both came equipped with a shell lifter with a semi-circular cutout at the forward edge. If not loading carefully, your thumb can get jammed up by this feature.
I know their are aftermarket replacements lifters that delete this feature. My question is what is the purpose for this cutout??? I figure the engineers that designed the guns put it there for a reason, but I can’t think of any practical purpose for it! Can someone enlighten me?!?!?
