First of all, congrats on having sence to leave MA, but also, we ask that you not bring the stereotypical Massitude with you. Being a gun person you peroberly don't need to worry as much - just don't expect warm welcomes from most real Mainer's.
Portland's just a few short miles from me. (I ain't livin' in land of Chitwood)
Ok
Now KTP will have the biggest selection but they don't always have the best prices, especially on used firearms. Some clerks ae ok, others are terrible, arrogant, and unschooled. Thier ammo/reloading dept is very well stocked too but again - prices are up there.
The shop in Biddeford OEF-VET mentioned has got to be Norm's.
THE worst shop I've ever been in to and also the one single place that has more crap flying around than a manure truck during a rollover.
There's Howell's in Gray on 202. Not a bad selection but also kinda overpriced unless you're one of his cronies. Got lied to and cheated there once so I'll never return anyways. (advertised one price, charged another
) Some nice high end shotguns though. Some clerks have that know-it-all attitude
I currently use Gulf of Maine gunsmithing on 302 in Raymond. Small shop with limited selection but a great guy to talk to. There's gunshows occasionally (
www.dipromo.com) has most but a Lewiston show is one of the best. (March 19/20) Biddeford and Waterville shows are kinda blah.
There's some others if you want a bit of a drive and depending on what you're specifically interested in.
There's also a few good ranges/clubs in the area too. Falmouth Rod & Gun and Scarborough Fish & game. I belong to the first one.
Also, get used to lower prices than what you're accustomed to in the Commonwealth. And it's ALL legal up here.
