Duncan's Gunworks

Duncan's Gunworks Since 1949, Duncan’s Gunworks has offered personal service, superior knowledge and exceptional value to Southern California and around the world.

For over 70 years, Duncan's Gunworks has grown on a solid foundation of honest, knowledgeable and helpful personal service. Everyday, we help novice and expert gun owners alike find the right firearm for their needs.

and lasting customer relationship. Duncan's is your locally owned and operated full service gun shop, and we are dedicated to deliver you the best customer experience possible.
