Straight Arrow

Hello, I am new to the forum and I am looking for some input. I have been hunting for over 35 years and have owned several 870s, an 1100, an SBE and most recently a Vinci. The problem I am having is that on recoil with certain shells the rear of the trigger guard slams into my middle finger. This can really hurt and after several impacts I have quite a lump. This has occurred most with 3" HeviSteel shells (discontinued) at 1550 fps. It has not happened with target loads and some goose loads. I think the designers at Benelli wanted to make a striking (pun intended) statement when they extended the rear of the trigger guard. But by doing this they reduced the clearance between the guard and finger behind it. I also am not a big fan of the safety in front of the trigger - I do not find this ergonomic. I talked to Benelli customer service re: this a couple of months ago and they said I was the only person to complain of the trigger guard design. Any input?? Thanks.
