Question: Will it fit pt809?
Document: I was so excited to get these. Been looking forward to it ever since I first got my gun. I don't like the standard sights that come on my Taurus PT 24/7. After putting these one, my accuracy improved immensely. They contrasting colors make it easy to line up your sight and they are very visible even when you are in the dark. Easy to install. I highly recommend these sights to anyone who has a gun they will fit on.
The product was easy to install, fit as it should and seemed to be of good quality. However, upon taking my gun to the range, I fired about 5 rounds and the fiber optic element fell out of the front site and was quickly lost. I'm sure that it was a fluke - but that issue on top of other issues with the particular firearm I put them on, was too much. On top of that, the sights still had me shooting 8 inches low at 10 yards.
I have a new taurus pt111 pro...I was a little nervous as I had read some comments saying these sights were just ok... But I am so glad I ordered them! They fit perfect, I used a bore laser to set them and they are spot on... super easy to see... way better then stock. I am going to order them for my other taurus pt840 as well. Best upgrade around and well worth the money.
bought this product I good faith. rear sight fit tight and had no problem with it. front sight keeps working loose. contacted seller they told me to send both pieces back don't want to mess up rear sight because it fits so tight. ask them to send me new front sight and I would send back the bad sight when I got the new one. haven't heard from them. I guess they don't want to work with me.
these are really nice sights made of aluminum and steel not plastic.they were real easy to install and do they give a nice sight picture.this was the place to buy great price,fast ship.amazon is where it is at.
Wanted sights for the wife that were easy to see, this product does that and looks great. Fairly easy to install, but I took it to a gunsmith, minimum charge for install and has improved her aim.
Very pleased with this product. I received the sights quickly and they are exactly what was advertised. I would definitely do business with them again.
These sights are a great alternative to higher priced units. They work great in the dusk hours. They're not as bright in the day time but still clearly visible.A+
The pistol: Taurus 24/7 pro-LS (SS). It came equipped with the Heinie "straight-eight" double dot sight system, which I absolutely hated from day one. Contrary to what the manufacturer may tout them as, the one dot on top of the other was more of a distraction than a quick-to-acquire sight picture.
Someone just overlooked this during the design phase and nobody looking at it or handling ever caught it.I will caution on one aspect. Taking my original sights off was a week long chore that saw me twist off several 1/16" hex wrenches.
Answer: yes
