Striker-fired pistol enthusiasts, get ready to meet your new favorites – the STK series by Rock Island Armory. These sleek and powerful 9MM pistols are set to redefine your shooting experience with innovative features and impressive specifications.

STK100 Ultra

The flagship of the series, the STK100, brings a fresh take on striker-fired pistols and has been around for around 5 years. The new take on this proven handgun is the STK100 Ultra, which has a few improvements over the basic STK100.

These improvements include more aggressive grip panels, checkering on the backstrap area of the gun as well as where you’d conventionally find a gas pedal on the forward section of the frame, a straight trigger, and an integrated magwell.

Everything else about the STK100 Ultra is the same as what we’ve known and loved about the STK100: the aluminum grip not only adds a touch of sophistication but also strikes the perfect balance, reducing felt recoil without compromising on comfort for all-day carry.

The patent-pending frame design adds durability, providing all the advantages of metal at the price of a polymer. This pistol will fit in existing STK100 holsters.
