RIA’s first-ever striker-fired pistol, the STK100, chambered in 9mm. It is said to have the feel of a metal weapon but the price of a polymer pistol.

The Rock Island Armory STK100 comes with a two-piece aluminum grip to make it more durable and enough weight to allow for less felt recoil by the shooter but still is comfortable to be carried or shot for extended periods. The STK100 also features a textured 1911 grip angle that a lot of folks are familiar with. The extended beavertail helps with a more natural point of aim, better control, and seating of the pistol in the hand.

The STK100 has a grip angle similar to a 1911 and has an extended beavertail on the grip for a more natural shooting hold. This helps with control by the shooter and the texturing gives friction for a better grip.

“Shooters are really going to be excited about the STK100,” said Armscor President and CEO, Martin Tuason. “It gives shooters all the advantages of metal for the price of polymer. It’s perfect for recreational shooting, self-defense, and even law enforcement, which makes it incredibly versatile.”

Patti Miller is one of the most awesome females in the tactical/firearm (or any) industry. Imagine a tall, hawt, dangerous Laura Ingalls Wilder type with cool hair and a suppressed blaster and you'll be getting the idea. What's interesting is that in addition to being a willing brawler and intrepid adventuress, she's also an Ent/Ogier level gardener and a truly badass baker.
