AAA Police Supply in Dedham Ma sells a small assortment of LE guns but Dicks in Dedham has a great selection of long guns at great prices both are 10-15 minutes from Dover...
I live in the area and I go to either ZHA or FS so that should tell you something about the
area. AAA supply in Dedham has been reported to be phasing out their LEO offerings as
well. Don't know that for sure since the last time I was in there was when I purchased
a 6" Model 28 with an 'S' prefix, brand new for $100.
