Question: Will this fit a Walther PPX?
Document: perfect fit for my 1st Gen Walther P99, good design quality manufacturing, rugged, would like to see it come in different colors
no idea. IN any case this thing is for fun/the range, it's not serious.
bought this laser at a gun show turned on a couple of times then it didn't work any more I haven't even put one shot with it if u really want a laser spend alittle more and get a quality one
The unit died after one use. I assume it's the battery. Looks cool, but  would not risk my life on it.
Quality laser, very well made at a reasonable price. I would recommend this to anyone that needs to buy a post, I shopped around and for the price you can't beat this
Purchased this to go on a Sig Sauer SP2022 40. caliber. Was concerned about it holding a zero but it did so just fine. I've put over 200 rounds through the gun with the laser and it has maintained a zero just fine. Not the brightest laser in the world but for the price it's nice.
Pros: Easy to install. Laser works great!Cons: No batteries included. Adjustment for laser pointing are a bit loose. Not sure if settings will stay in place over extended shooting.
I received the laser sight and within 10 minutes i was sighting in on the iron sights. I will be at the range in a week or so to fine tune it. So far i really like it. It went on so easy and looks good.
I bought one after turning it on about three times it quit they want to charge for shipping back to them I buy on amazon because I work all the time and I'm not taking off to mail this back mark it up as I should of know better.
Came with a manual, batteries and an allen wrench for adjustments, all in a small black box with foam cutouts for everything..that part was impressive. Now, for $20 what can we really expect..You need to dial this thing in for whatever range you want, as the adjustments are crazy. For example,  dial the laser to sit on the front sight post at 5 yards, and the beam is nearly a foot high at 20 yards.
Answer: yes
