About Second Amendment Sports

Long before Second Amendment Sports was even an idea, Bert Irslinger Sr. and his son, Bert Jr. were just gun collectors with a passion.

Whether it was a military piece, a cowboy classic, or a high-performance feat of modern gunmaking, the father-son duo were avid fans, hunting down all kinds of high-quality firearms. They traveled the gun show circuit, in search of anything rare or that caught their eye. As their hobby grew, they started making more trips further out of Illinois, and their collections flourished. As they branched out to other states, getting purchases home became increasingly difficult, forcing them to have vendors send the guns to licensed third-party firearm importers back home. They needed a solution to streamline the process.

To cut out the middleman and the hassle, they applied for their own Federal Firearms License—an application which required them to open a gun store in McHenry stocked with product. They put out word that they did FFL transfers, but didn’t expect such a huge response.

Even without advertising, business picked up fast. The founders’ passion, customer focus and expertise shone through, and demand kept pace. When clients offered firearms to trade, they started acquiring more used pieces. When the calls started coming in more frequently, they hired staff and moved to regular hours. When product consistently sold out, they started ordering more and forming vendor relationships to keep cases stocked. When the customer base outgrew their storefront, they started looking for a bigger location.

Soon enough, Second Amendment Sports was an established presence. What had begun as a modest enterprise transformed into a professional, structured business. Bert Sr. and Bert Jr. embraced this shift and the opportunity to better serve the gun community, building close relationships with top manufacturers and local dealers.

Second Amendment Sports has grown into a polished company with plans for further expansion, but the original motive was simply a passion for the gun industry. It’s this love that drives the staff’s dedication to their work. You won’t get this level of customer care, expert advice, and exacting standards for quality at any other gun store.
