Glowing bright both day and night, TFX™ sights are always ready. TFX™ takes the TRUGLO award-winning Tritium + Fiber-Optic technology even further with all the features their customers requested: compact snag-free design, longer sight radius, and amazingly durable construction built to handle just about anything. Illuminating elements are encased inside a virtually indestructible chemical and shock-resistant capsule and the CNC-machined steel is protected with a rust-proof FORTRESS FINISH™. There is even a highly visible white ring surrounding the front fiber to make it even more visible, encouraging the eye to rapidly focus on the front sight for a fast and accurate sight picture. TFX™ sights will amaze even the most discriminant shooters.
S&W® M&P (including SHIELD & .22 models, excluding .22 Compact / C.O.R.E. models), SD9 and SD40 (excluding VE models)
I've carried TFX sights on my duty pistols for the last 3 years, when I changed departments. I had the Springfield model on two XDm and an XDS, and now I have the M&P model on a M2.0 full size, M2.0 Compact 3.6, and M2.0 Shield.
They are very durable, with no durability issues whatsoever. They perform excellently, in both daylight conditions and night time conditions. The fiber-optics really pop during daylight shoots, and the tritium is easily seen in low/no light.
Only complaint is the S&W models slope on the front edge of the rear sight, and don't have a hard edge. It makes emergency one-handed racking of the slide a bit more difficult. Since this is a drill we practice regularly during training, I've had to train on a new technique.
Overall, happy with them, and will continue to put them on all of my handguns.
Dontt expect to last long. Or have good warranty, if you have to get a replacement. Company wants you to send slide to get a repair. Pay to send item and 12.50 processing/shipping. Have had item less than 8 months put 200 or so rounds at range. Last a couple of years yeah right. Company doesnt take consideration this may be only gun or what would you use for self-defense.
