Rock Island STK100 4.5" Optics Ready 9mm Pistol, Black – 56625

I have 3 ria 1911s, and theY are all fantastic. I grabbed this model as I do noT liKe glOck grip angle, and the stk100 seems to give a 1911 on a striker fired 9mm. I sent it back to armscOr once after it haD Constant fte and lrbho problems the first 150 rounds. The armscor gunsmith Reported that the firearm is fine, but maybe sensitive to ammo and sent it back. Now, with the select ammo that works at all, 1/10 rounds fte, 1/4 magazines have lrbho failure. I believe it is s poorly designed firearm that has the potential to be great if they fix all thr glitches.

I read the instructions and did a thorough cleaning and used the recommended grain. Took the stk100 to the range with zero malfuntions. love the grips of the pistol and it shoots smooth and flat. fyi... the he507k-gr x2 reflex optical sight fits the same footprint for the stk100. I also bought extra kci magazines with the full metal sleave insert with no issues what so ever. also purchased a vedder iwb glock17 holster and fits like a glove. ???????????????? have a blessed day

good trigger, good feel, will shoot 1 t0 2" groups @ 10yds with Vortex. Must clean gun completely before shooting and not use cheap ammo or you will get fte. if you don't take these steps you will get the results one of the other reviews talks about. very comfortable gun to shoot

Great GUN. HEAVIER than plastic which helps with recoil and RE-Acquisition. Accurate. Breakdown a challenge at first but OK after you figure it out.

I like the gun, could use a little more attention to screw holes as aluminum grip is sharp at holes, gun needs attention to protection and trigger care and pull..

Very accurate pistol and feels great in my big hands… just wish it had better rear Iron sights…but for the money this is a well built designed and pistol????

This gun is owesome..I like the look of it..first time I took to the range today..fun to shoot..I have one failure to feed after feeding 150 rds for the first time..maybe ok after the break in period..certainly recommend this RIA pistol

These are great pistols, I love mine. It is a nice pistol for people that like the 1911 grip frame angle. Takes Glock Mags.

I will confess to being a Rock Island fan. I own a half dozen of their weapons and have never had a misfire or an issue with any of them and I was looking forward to this offering from them. This is one of the more unique guns on the market. If you are reading this you probably know the basics but for it a quick review, this high cap Glock knockoff has a few items that make it more enjoyable than the standard Glock 17. To begin with, it's an all aluminum frame and designed in a clamshell

This gun fits perfectly in my 2XL hand. I love the grip angle and the gun sits low enough in my hand to get on target quickly. My Vortex Venom fit perfectly on the optics ready slide. I've put about 300 rounds through it with Pmags and inexpensive target ammo with no problems. Insta @rips_guns
