Previous importer, distributor, and retailer headquartered in Waseca, MN from early 1960s - 1979. Herters also had additional retail stores scattered throughout the upper Midwest.
Herters subcontracted various manufacturers (mostly European) to fabricate Powermag revolvers, U-9/J-9 rifles, and shotguns which were mostly patterned after more famous original models. Most of these copies were designed to undersell the competition at the time and while quality in most cases was quite good, consumer sales were not strong enough to continue production. While many Herters models are relatively rare, collectibility to date has been minimal. Herters model values are usually under the original trademarks from which they were derived and to date have been based more on the shooting utility than the collector potential.
