Mainstream Firearms & Marine

Mainstream Firearms & Marine got its start in 1989 as a family owned and operated pawn shop. With a growing inventory of firearms, the business evolved and soon became the area’s go-to store for firearms and ammunition. Today Mainstream has more than 1,000 new and used firearms in stock. In 1995 Mainstream became the Midwest dealer for Go-Devil boats and motors. All of Mainstreams in-store and online sales are backed by friendly, knowledgeable service.

Operating under the principles of honesty and reliability, our number one priority is customer satisfaction. That’s how we have built a following of return customers who now make Mainstream their first stop for guns, ammunition and Go-Devil boating supplies.

Mainstream sells guns and reloading supplies from a range of reputable manufacturers. Our firearms are sold in-store and at Years of experience has resulted in firearms expertise and know-how that is second to none. Our appraisal services are well-known and requested throughout southeast Minnesota.

At Mainstream we are all avid hunters, competitive shooters and outdoorsmen. We take advantage of the area’s waterways and hunting lands. We use what we sell and apply that expertise daily to help customers find the firearms or Go-Devil boats, motors and accessories that best fit their needs.

Mainstream also has strong community roots in the Winona, MN area. We continuously support local sportsmen groups and shooting sports throughout the region. It’s very rewarding to volunteer our gun expertise for local fundraisers and banquets that have helped multiple organizations raise maximum profits through successful gun raffles.
