\"Rock<\/figure>\n\n\n\n

The Rock Island Armory \/ Armscor STK100 is a 9mm striker-fired pistol with a two-piece patent-pending aluminum frame that gives shooters a low bore axis and a 1911 grip angle. This is a serious full-size handgun with the stability you expect from a long sight radius and a 17 round magazine and an MSRP of $599.<\/p>\n\n\n\n

Philippine based manufacturer Armscor is famous for its 1911 style pistols. They have won a place in the market as feature rich and high value. The innovative STK100 shows its 1911 heritage and the experience of an established arms company with a deep culture of quality.<\/p>\n\n\n\n

I have several Rock Island Armory 1911’s. I have always liked them and found that they had a lot of custom features and good accuracy at a reasonable price. When I got the chance to shoot their new striker fired gun, the STK100, I jumped at it. I found it innovative and fun to shoot and I think you might like it too.<\/p>\n\n\n\n

\"Rock<\/figure>\n\n\n\n

Frame<\/h3>\n\n\n\n

The solid aluminum frame gives STK100 heft for smoother shooting with reduced felt recoil. Since aluminum doesn\u2019t flex like polymer, the STK100 promises improved accuracy potential.<\/p>\n\n\n\n

The 1911 style ergonomics provide a great natural point of aim. The grip is grooved on the backstrap in a V-pattern and the front horizontally. The sides of the grip have very effective stippling. The undercut trigger guard enables a high grip on the gun in the modern fashion. All these features result in a solid grip for dynamic control.<\/p>\n\n\n\n

\"Rock
The rails on the STK100 are long and offer substantial support for the slide.<\/figcaption><\/figure>\n\n\n\n

The innovative (patent pending) clamshell frame design is made of two pieces joined by six bolts. The trigger parts are very familiar to Glock users, but where other guns use pins, the STK has screws to secure the parts. The dust cover has a section of Picatinny rail for mounting lights and lasers.<\/p>\n\n\n\n

\"Rock
The frame-mounted rail readily mounts lights like this Streamlight TLR-8 G.<\/figcaption><\/figure>\n\n\n\n

The grip surfaces provide a solid grip without being overly aggressive. The frame has a nice matte anodized finish which I find very appealing. The dust cover has extended rails. There is a captive recoil spring on a stainless steel rod.<\/p>\n\n\n\n

Slide<\/h3>\n\n\n\n

The slide is a thing of beauty, machined from a billet of carbon steel. It features angled cocking serrations in front and rear. Seven lightning ports, (three on each side and one on the top) reduce slide mass which speeds up cycling for better reliability and potentially less muzzle flip.<\/p>\n\n\n\n

\"Rock
The slide is a thing of beauty, machined from a billet of carbon steel with angled cocking serrations in front and rear. <\/figcaption><\/figure>\n\n\n\n

The barrel measures 4.5\u201d\/114 mm, with conventional six-groove right-hand rifling and a 1:16 inch twist. This twist favors faster bullets like the 115 grain. Heavy and slow bullets may not stabilize. The barrel and slide do not interchange with Glock parts.<\/p>\n\n\n\n

\"Rock
Ringing steel at 50 was a little tricky but quite possible. I hit about half of my shots.<\/figcaption><\/figure>\n\n\n\n

Sights<\/h3>\n\n\n\n

The interchangeable front sight has a white dot. The fixed rear sight, mounted on the rear cover plate, is serrated and solid black. I found the STK100 shot about 3 inches low at 15 yards. The sight radius is 7.9\u201d\/201 mm. The STK100 can mount the sights already on the market designed for GLOCK pistols. When you remove the cover plate, you see that the slide is cut for direct mounting a Vortex optic.<\/p>\n\n\n\n

Controls<\/h3>\n\n\n\n

As for the controls, the magazine release button is reversible, while the slide stop lever is on the left side only. The trigger is similar to other striker-fired guns, there is slack, a wall, and a break. My STK100 has a trigger break of about 5 pounds.<\/p>\n\n\n\n

Assembly and Disassembly<\/h3>\n\n\n\n

Like other common striker-fired guns, to disassemble the STK100, you must de-cock it, then move the slide back a fraction of an inch while pulling down on the slide release levers.<\/p>\n\n\n\n

Weight<\/h3>\n\n\n\n

The unloaded STK100 weighs in at 28.8 ozs, light enough for everyday carry. This is slightly more than the Glock 17 at 22.2 ozs but less than a full-size Sig 320 9mm at 29.5 ozs. The added weight mitigates the recoil impulse and provides a more stable platform for follow-up shots. Aluminum frames won’t flex like polymer frames so there is greater accuracy potential.<\/p>\n\n\n\n

Shooting<\/h3>\n\n\n\n

The weight and balance of the STK100 make it smooth shooting and easy to manage. There\u2019s a little take-up as you engage the trigger safety, a wall, then a break at about 5 pounds. The reset is short.<\/p>\n\n\n\n

\"Rock
Up close, the STK is fast and stable.<\/figcaption><\/figure>\n\n\n\n
\"Rock
Plenty of accuracy for self-defense and practical uses.<\/figcaption><\/figure>\n\n\n\n
\"Rock
The STK100 had acceptable accuracy with 115gr ammo out to 25 yards. These are 1\/2 scale targets.<\/figcaption><\/figure>\n\n\n\n

Holster Check<\/h3>\n\n\n\n

Even though the trigger guard looks big, the STK fit the Glock holsters I checked. Your experience may vary.<\/p>\n\n\n\n

Ammo Compatibility<\/h3>\n\n\n\n

I had no problems with ammunition. I fired about 200 rounds through the STK100. One hundred rounds of ARMSCOR brass and 100 rounds of steel cased TULA, both 115 grain. I tried a few groups with 124 grain rounds and found that groups were noticeably larger.<\/p>\n\n\n\n

Magazines<\/h3>\n\n\n\n

The STK100 shipped with KCI USA 17 round magazines. My experience with KCI USA magazines has been very good and this was no exception. I also tried Glock OEM magazines and had two failures to extract but absolutely no problems after that. <\/p>\n\n\n\n

\"Rock<\/figure>\n\n\n\n

The STK100 is a solid performer with some interesting features. I like the 1911 grip angle, beaver tail, and aluminum grip serrations. The weight, ergonomics, and low bore axis reduces felt recoil and enhances rapid target transitions. It is a full-size gun but still suitable for everyday carry while still being comfortable to carry all day. If you want a striker fired pistol with the heft and feel of the 1911, you have come to the right place.<\/p>\n\n\n\n
