Tarnhelm Supply Co., Inc.

Tarnhelm Supply Co., Inc. is the sole authorized installer for Magna-Trigger smart gun technology—a field-proven safety system that's been in use for over 20 years. The device works with a magnetic ring that allows the gun to fire only when worn, making it ideal for home defense in houses with children. Police departments and hospital security forces use this technology.

Magna-Trigger Pricing: - S&W K, L, N frames: $360 - S&W J-frame and Ruger Security Six: $750

They also install the Murabito Gun Safety for revolvers ($150)—giving you a manual safety lever on guns that don't normally have one.

For GLOCK owners, Tarnhelm offers manual safety installations on all GLOCK models, including the M-36. They also provide grip reduction service for shooters with smaller hands—a modification that's especially popular after Massad Ayoob's coverage.
