  • Great dot!
Worked good for me. Nice visible dot. Fits the factory p229 slide if it comes optic ready.

  • True to their word
Was looking for an optic for my p320. Stumbled on a review for this optic and liked what they said. Stalked about 6 more reviews and was still sold on it (hoping it was as good as they said) it was! So far . Put it on in less than 5 minutes. The circle looked like a burst and figured I'd have to where my glasses for crisp lines. I was wrong! at 6 yards, 11 yards, 25 yards I could see the lines with very little burst! I didn't need my prescription glasses on to make the view crisp , almost no burst (like on a different Holosun on. Took to the range, spot on!! No adjustments needed!(for me) Just 100 rounds Let's see over time and use to see how it holds up but as for now definitely a believer!! ... show more

  • Big FAN!
I love the big window! I have used the EPS extensively through training classes, competitions, as well as EDC. This optic addresses the issues I had with my EPS. The light detecting sensors work fantastic. I have not been disappointed with the selected power settings. Installation is a breeze as with most optics. I have not specifically the build quality of this but there are several videos that directly address this on YouTube. Again, big fan of this optic. Looking forward to running it more next season! ... show more

  • Optic work great
Fits perfectly and flush on my Shadow Systems MR920P. Love that I don't have to replace the batteries, because the solar panels recharge the internal batteries.

  • Perfect fit on the Pro Cut slide
I considered several adapter/ filler plates for the Pro Cut slide to match with a Holosun 507 before finding this. I know the Sig p365 series have all the glory nowadays , but this is a beautiful direct bolt-on for the p226 Pro Cut slide, also. Remove the filler plate and screw this down exactly in it's place with the pre threadlocked screws and the tool provided in the box. The side relief cuts even compliment the ones on the Sig Slide. Looks awesome, matches great, and has better features than the Romeo series. ... show more

  • Beware This Might Not Fit your Sig P320RX
I was all kinds of excited to replace my original Romeo 1 on my Sig P320RX with this. It looked great. Found out that it will NOT fit my pistol. Talked with Holosun and they said it was for a 2022 or newer. Would have been great if the website had mentioned that. My Sig P320RX is at least 5 years and I purchased it new. So once I removed my Romeo 1 I noticed that the slide cutout was for a very slight dove tail. The new Holosun SCS 320 was slightly too large to fit in the cutout. Also the screws provided would not have worked in my slide. They were just also a slightly large screw. My recommendation prior to ordering this is to talk to Holosun to make sure this SCS 320 will fit your particular Sig 320. Disappointed. Turns out that just because they named it 320 doesn't mean it will fit your Sig 320 and certainly not the older Sig 320RX. Go figure. Perhaps if they made a model to fit both the new and old Sig 320 and maybe let you look up by pistol serial number which model you should order it would save everyone a lot of time. Fortunately with Amazon returns are easy. $400 for a green dot that doesn't fit the Sig cutout?? ... show more
