The challenge

The Challenge

Firearm shops rely on traditional fitting methods built on guesswork and trial-and-error. Without precise hand measurements, customers end up with firearms that don't fit — compromising comfort, accuracy, and safety — while fragmented sales, inventory, and multi-location ops add another layer of complexity.
