TruGlo TFK Pro Fiber Optic Sight

Note these are my first aftermarket sights, but I did a lot of research and analysis before buying and felt the TFX Pro was the best option. Your needs may lead to a different choice. Regarding installation, I completed the install on my S&W Shield myself. It took about an hour because getting the old sights off can be a bit of an experience and effort, but the new sights went on more easily, and I also did some fine tuning to get the sights centered. Much of the time was being careful because I was concerned all the pressure to push the sights off and on was going to deform or break the sights, but nope not at all. I did rate the install as 5 stars, but that doesn't mean it's easy. It's just easier than the stock sights and I didn't have any hang-ups during the install. Again, you just need to make sure you still the sights centered correctly. ADVICE 1: Get a good sight pusher. Using the hammer and punch was killing my punches and the sights wouldn't even budge. I could have gone harder but I didn't want to risk marring the slide, so the pusher proved to be much better. Note that I found it useful to clamp the pusher in a vise so it was more stable and less prone to slipping out of my hands. ADVICE 2: Before installing the new sights, use a sharp pencil to mark the center of the top of the slide while the old sights are in place. It will make it easier to center the new sights. I tried to use calipers to measure the center, but it was hard to get a good or consistent purchase when measuring, so I didn't get the accuracy I was looking for. I wish I had marked it. Or having a reputable gunsmith install the sights may be the easier way to go, just make sure they care enough to center the sights correctly. ADVICE 3: Apply a light coat of oil into the dove cuts with a swab so the new sights go on more easily. ADVICE 4: Many pistols have a set screw on the rear sight to ensure it doesn't move. You will need blue thread locker on the set screw so it doesn't come loose. So after the install, I just practiced some draw and and target acquisition. I literally could see an improvement after like 6 draws. It's really easy to get used to, and it's really easy see whether the dots aligned correctly, especially with the orange circle front sight. I wish I bought these a long time ago. I was concerned about the tritium/fiber being too bright when in the dark, but not the case at all. They are low key enough that if you needed to hide yourself, they wouldn't show, but have good brightness to still be plenty visible. I'll still have to try it in mixed lighting to see if the green dots are still easy to make out, not sure. I really liked the rear sight having a ledge that I could use for one-handed racking. It's also useful for my friend, where she doesn't have a lot of grip strength to rack the slide, so having the ledge makes her life easier as well. That's about it. Well worth the price and they look great. Now I'm going to buy more for my other pistols. Enjoy.
