Pete's Gun Shop began as a hobby in 1956, run by it's founder, Peter Decker, out of the front office of his family business, Decker's Cleaners and Dyers, on 31 Columbia Street  in Adams, MA. The gun business grew by leaps and bounds, and eventually eclipsed the cleaning business in scope. The cleaning business was eventually downsized, and the gun business became the main concern.

In 1983, the former building was remodeled with a concentration toward allowing more space for guns. In 1992, following the death of Pete's wife, Elinor, the cleaning business onsite was closed, and any cleaning was farmed out to a subcontractor. In the late 90's, while demolishing an electrical substation next to the former cleaners, National Grid found the presence of severe pollution dating back to the existence of a co-generation facility run there about 100 years previously. Negotiations were entered into to try to clean up the pollution which was present beneath our building.

In 2004, Peter Decker passed away after a very short illness. The present owner, Tom Decker, found himself with a gun shop business, and a polluted property that was still embroiled in a fight with the polluter, National Grid. When negotiations again progressed, the former building was sold, paving the way for our new shop at 9 Grove Street in Adams. The new building is a wonderful place, with period decorations and a warm atmosphere, welcoming to any and all. We have a wood stove and a sitting area, as well as the largest inventory of guns in Western Massachusetts.

Shortly after moving to the new building, we also added a full line of archery equipment with the establishment of an archery Pro Shop, featuring Hoyt Archery products. We have full time archery staff on site to assist you with your every need.


The new owner, Tom, has a lifelong love of guns, taught by his father Pete, and has made Pete's a welcoming, friendly place to visit and find your next firearm purchase. We are unlike any gun shop you have ever visited, so stop on by and see for yourself!
