M2 with rifle sights

[mcook]

I have an M2 model # 11054 which comes with rifle sights. I was wanting to change them out with some type of 3 dot system such as Tru-glo or something similar. I can't find anything listed specifically for this Benelli stock number. The back sight is a dovetail type mounted similarly to the way the back sight on a Glock 17 or 19 is mounted.  I can't tell how the front sight is attached. I was hoping not to have to do any heavy modifications to the barrel. I am comfortable doing basic tasks with the gun but am not a gunsmith. Any information would be appreciated.

Thanks
