installed this on my wife's PPQ. PPQ factory trigger is already quite good except for the pre-travel. With this design, the pre-travel is minimum. The trigger breaks at 90-deg with almost no over-travel. I just hope they have one for the Q5 SF as well.

I purchased 4 different buffers (normal, H1, H2, H3) for my first rifle to tune it for reliability when suppressed and minimum dot movement when unsuppressed (for competition). Then I found this adjustable buffer which costs much less than the total of those 4. I've used the adjustability for several occasions and it works well. I put a little blue loctite on the two screws (holding very well, but can be removed). I ended up buying more for my other rifles and "pistols".

This is perhaps the best 2.5moa red dot: large window, crisp dot, robust, hold zero after 4000 rds. This red dot is taller than the RMR or the SRO, but with some reps it becomes a non-issue. The brightness adjustment may take sometime to get used to, but it is not a big deal.
For competition shooting, I hope Leupold will come up with a 5moa dot version (I don't like the 7.5moa triangle reticle).

A friend told me about this and I was skeptical since the Shadow 2 shoots flat already with 147gr competition load. I tried it out (using the medium plug and the 2nd lightest spring) vs. 11lb recoil spring (from CGW) + factory guide rod. The difference inn muzzle flip shows with the Mantis kit. I am quite impressed.

I ordered this for my Galil Ace 7.62x39 rifle. Since the piston for the Ace is held with a roll pin, it was easy to remove the factory piston and replace it with the KNS piston. But I noticed that the roll pin size (and the hole) for the KNS is smaller than that for the Ace. As I was trying to find a good setting (reducing the gas flow), I started getting numerous malfunctions. I dialed it back to the highest setting and the malfunction still happened (FTF and FTE). At some point, I couldn't even rack the BCG. After forcing the BCG to move forward and cleaning it quickly, I reinstalled the factory piston and the gun worked again. So I ended up returning this to OPP. Given the stellar reputation of the KNS piston, I wonder if perhaps I should ask a gunsmith to drill a larger hole on the KNS piston (to fit the size of the hole from the factory piston carrier) so that the piston sits tighter on the carrier just as the factory piston. If so, I guess it is a user error. But for now I am giving 3 stars from my experience. Take it with the grain of salt.

I purchased this light for my Glock 19. After about 200 rounds the light started to flicker when shooting. Contacted Inforce, asked to ship the light with my own cost and about 4 weeks later I received a replacement. It seems to work so far.

On par with the Romeo3Max with the same footprint as RMR. So far my second favorite red dot (after Romeo3Max). The 5moa dot is crisp, fewer brightness adjustment than Romeo3Max, but so far I don't have any problem. Mounted it on my Shadow 2.

Clear and wide lens, crisp 6moa red dot with more brightness setting. So far 3000 rounds and it still holds zero and is going strong (mounted on a milled P320 XFive Legion slide). Lens holds well, the body near the ejection is a bit scratched (due to brass) but nothing major.

I have two RomeoZeros. With $50 more, HS407K has a lot more to offer: tactile and precise windage and elevation adjustment, solid body (aluminum vs polymer), robust, and the 6moa dot is crisp and clear. I have compared this to the RMSc (almost 2x more expensive), still preferring the HS407K.
I will buy more HS407K/507K when the X2 versions come out.

Purchased one for my Glock 19 Gen4 with S3F threaded barrel. Installation was easy. Shot about 400 rds (various 115gr and 124gr), it worked flawlessly with the factory guide rod. With a lighter 15lb recoil spring and the Glockstore tungsten guide rod, the gun shoots even softer and flatter. The hotter the ammo, the flatter it shoots (S&B and +P).
Note: often times the slide doesn't lock back when the mag is empty although the gun cycles just fine.
The overall setup fits in my Glock 34 holster.
