I purchased my USA Defender back in January, 2015, and just now made time to shoot it at a local gun range. I am so pleased with the performance. It’s definitely a two handed gun and it delivers. I read all the testimonials on the various models and watched the videos before I chose the USA Defender. Pure quality in a firearm. In addition to the standard 410/45 Colt , I purchased the 38/357 barrel and 22 mag barrel. I fired the gun today and tried all the barrels. I am very pleased and can’t say enough about this firearm. I would highly recommend it. Thanks To Gordon at Bond Arms for making such a quality firearm to allow us to defend ourselves and family from those that would bring harm,as well as, for sport shooting.
