Inside Milt Sparks Holsters: A 55-Year Idaho Legacy Built on Leather, Craftsmanship, and Patience
In Garden City, Idaho, tucked inside the greater Boise metro area, a small leather shop is doing something rare in modern manufacturing — taking its time on purpose. Milt Sparks Holsters has been producing handcrafted leather holsters for more than 55 years, and today the company carries a 10-month backlog on custom orders. For co-owner Nick Harvey, that wait list is not a problem. It is proof that the business is working exactly as intended.
From a Wartime Purse Kit to a Firearms Industry Legend
The origin of Milt Sparks Holsters is as unlikely as it is distinctly American. During World War II, Bonnie Sparks purchased a handicraft kit to make a leather purse while her husband, Milt, flew Navy planes overseas. When Milt returned home, he picked up the hobby himself, eventually crafting flight bags for fellow pilots. By the late 1960s, that quiet pastime had grown into a business, starting in Star, Idaho, before eventually relocating to Idaho City.
The company’s national reputation took off in 1976, when Milt Sparks became involved with Col. Jeff Cooper — the legendary firearms instructor who shaped modern pistol technique and helped establish what would become IPSC competition shooting. Sparks holster designs were used in those early competitions, and word spread quickly among serious shooters across the country.
In the 1980s, craftsman Tony Kanaley joined the shop and rose to become shop manager. When Milt stepped back from daily operations, Kanaley purchased the company in 1990. Milt Sparks passed away in 1995, but the business he had built from a pilot’s patience and a purse kit continued without interruption. Nick Harvey joined the team in 2000, and when Kanaley was ready to retire, Harvey partnered with longtime colleagues Jim Wall and Scott Kubik to purchase the company in 2017. Wall had been with Milt Sparks since the mid-1990s, and Kubik had been part of the team for nearly 28 years at that time.
“We all have quite a bit of institutional knowledge in that regard,” Harvey said.
The Craft Behind Every Holster
What sets Milt Sparks apart in a market crowded with polymer holsters mass-produced on assembly lines is a commitment to doing almost everything by hand — and doing it slowly. Cowhide arrives primarily from Herman Oak in St. Louis, a tannery known for producing some of the finest vegetable-tanned leather in the country. Horsehide comes from Horween Leather in Chicago. Thread, dyes, and adhesives are all American-sourced.
Every holster is built by a single craftsman, from the first cut to the final burnish. The process includes cutting the leather, stitching, wet-molding to the exact shape of a specific firearm, pressing at high pressure, and hand-detailing before the piece ships. When the work is done, that craftsman presses their initials into the leather near the seam — a quiet mark of individual accountability that follows the holster for the rest of its life.
“It’s our way of signing the holster,” Harvey said. “Someone made this and was willing to put their name on it.”
Harvey has reportedly spotted his own early work listed on eBay years later, tagged as vintage, still carrying his initials. For Ada County residents and Second Amendment supporters who appreciate American-made goods, that kind of traceability is a selling point no factory can replicate.

Impact on Ada County’s Economy and Small Business Community
Milt Sparks Holsters operates as a small, tight-knit team in Garden City — the independent municipality nestled within the Boise metro area along the Boise River. The company represents the kind of artisan manufacturing business that anchors local economies without requiring government subsidies, large office parks, or outside investment. It is a privately held, family-run operation that has changed hands through personal relationships rather than corporate acquisition.
The 10-month backlog is, by Harvey’s own account, a choice. He is candid that demand exists to grow the company faster. The infrastructure to scale is visible. He has simply chosen not to pursue it — a philosophy that reflects a deliberate prioritization of quality over volume in a free-market environment where consumers are voting with their patience and their wallets.
“People are willing to wait,” Harvey said. “They’ll say, ‘I’ve heard about your product and I’m willing to wait.’ That’s worked out really well for us.”
That kind of consumer confidence in a small Idaho business stands in notable contrast to broader economic pressures facing Treasure Valley residents. Gas prices in Boise have climbed again in recent weeks, adding cost pressure to households and small businesses alike — making locally rooted success stories like Milt Sparks all the more noteworthy.
What Comes Next
For prospective customers, the path to owning a Milt Sparks holster begins with placing a custom order and committing to the wait. The company’s Garden City workshop continues to operate with the same hands-on production model it has maintained for more than half a century. For Ada County residents interested in supporting American-made, Idaho-based craftsmanship, Milt Sparks Holsters represents exactly the kind of durable small business that defines the Treasure Valley’s entrepreneurial character.
