In my quest for a reputable gun shop to order a specific turkey shot gun, I consulted my friend Clint Morgan. He recommended Monadnock Firearms. I couldn’t be happier. When I ordered the firearm they said it would be 1 to 2 weeks. 3 days later they called and said it was in… now that’s service. They were friendly , answered all of my questions and made it a point to make sure I was completely satisfied. Thank you !

1 year later and Bam! Once again The mighty 410 strikes again. If you want to have some fun go see Rob at monadnock firearms and he will hook you up with a Dynamite small bore turkey slaying shot gun!

May 28th 2025 with time running out the little 410 struck its final blow for the season. 52 yards and dropped the long beard in his tracks. Thanks again to Rob for finding me an amazing turkey guy!

I've bought several rifles and handguns from Monadnock Firearms. Everyone is extremely knowledgeable and helpful. I would highly recommend them to anyone needing firearms. Great selection and they will order anything they don't have. They have access to all major manufacturers and suppliers.
