About Us

SL Gun Shop was founded in 1998 by Paul Gauffin, who had operated a part-time firearms repair business in Leominster, MA since 1985.

SL Gun Shop in Mason NHSL Gun Shop’s original focus was on building a repair business to augment occasional retail sales, but over the years, the company grew in a different direction, with gun sales outpacing repairs.

Today, SL’s inventory consists of over 1200 firearms of every description. As one of the largest volume shops in New Hampshire, we retain a strong repair capability, with 3 gunsmiths and a skilled machinist on staff. Custom gunsmith work has become a hallmark of our repair shop. We routinely perform a wide variety of repairs and modifications on virtually every make, model and type of firearms. We are a federally licensed firearms manufacturer, capable of product development and prototype work in the firearms field.

We guarantee and stand by what we sell. SL enjoys a reputation for honest, equitable, straightforward business dealings. It is a reputation we intend to maintain and enhance in the coming years.
