Well it was the first time I've ever done real work on a gun before. I took off the stock sights and installed XS Big Dot 24/7 sights.
These make a huge difference in low light situations for in my home. I'm so glad I got them and these are very easy for me to put on target. Going from a well lit area into a room with a light off but the door open I can actually see where I'm pointing now! I tried the same thing with my Kahr MK9 (no night sights) I was pointing blindly and really could not tell where I was pointing past a few yards accurately.
These sights are not overly bright either. The front sight is supposed to be brighter then the rear one which works out great for me. They are not bright enough to glow through any of my shirts.
