You spoke — our Armscor team listened. The STK line of firearms is the direct result of shooter feedback, reimagined into a trio of aluminum pistols that shoot smoother, carry smarter, and feel better in hand. Whether you’re after full-size firepower or concealed carry confidence, the STK lineup is designed with real-world use in mind.
These aren’t just updates. They’re upgrades inspired by you. With better grips, smarter sizing, and pro-level touches like optics-ready slides and flat triggers, the STK series reflects what today’s shooters actually want. It's a product series born from experience — and built for yours.
The aluminum frame adds welcome heft, reducing recoil and muzzle flip. It’s a noticeable upgrade from polymer competitors, offering a premium feel without breaking the bank.
Each model serves a purpose:
While each model may work best in certain environments, they are all great options for anyone looking for a reliable handgun.
“All three options are great for range day guns and everyday carry,” explained John. “You can use any of these guns for a multitude of purposes.”
Additionally, all three semi-automatic, striker-fired pistols ship with two optic plates for RMR and RMSc footprints. Each handgun should also be compatible with select aftermarket magazines if you should prefer more rounds.
Let’s meet the standout models — STK100 Ultra, STK150, and STK200! Find out which one is right for you.
The STK100 Ultra isn’t just an update — it’s a full reimagining of Armscor’s original STK100. With a 1911-style grip angle, deeper checkering, a flat-face trigger, and suppressor-height sights, it’s built for control and comfort.
"We redesigned the grip to feel less like a Gen 3 Glock and more like a 1911," John said.
It also features a machined magwell into the bottom for smoother reloads and a flat-face trigger that offers a more aftermarket feel.
This full-sized 17+1 pistol is ideal for range days, duty use, or open carry.
Want a bit more concealability without sacrificing capacity? The STK150 blends a compact slide and barrel with a full-sized grip, still giving you 17+1 rounds of 9mm firepower. It also introduces a true, single-piece aluminum frame, unlike the clamshell of earlier models, and adds grip relief cuts to accommodate smaller hands.
It’s a sweet spot for those looking to carry all day with a slightly more compact footprint but full control.
For those prioritizing concealed carry, the STK200 is the one for you. It’s the smallest of the STK family with a true compact frame and a 15-round magazine. You still get ambidextrous mag releases, the aggressive grip texture, and full optics-ready capability — without skimping on handleability.
It’s nimble, reliable, and just right for inside-the-waistband everyday carry.
With the STK series, you don’t have to choose between tradition and innovation — you’re getting the best of both. Built for versatility, comfort, and precision, each model is ready for whatever role you need it to play. Whether you're a beginner or a seasoned shooter, the STK series is a great choice. If you’ve been searching for a pistol that shoots like a striker-fired and feels like a classic, the STK series might just be your perfect match.
