Hi guys, I just bought a SIG P226 with the XS Big Dots installed and wanted to give my impressions. First off, I think they're good quality sights. The tritium inserts are bright and easy to see. But personally, they're not for me. That big front sight is very easy to see, and does allow for a very quick acquisition of the front sight. However for me, the front sight is actually a little too big for precise shots. If someone was charging you, and you only had a split second to draw a bead, they'd be fine. But that V rear sight doesn't allow for my eyes to make a precise lateral alignment. For gross aiming, they'll do. While I'm not a great shot yet, I'm "pretty good". I'm sure I could get body hits, but I wouldn't feel comfortable trying a head shot at more than 10 yards or so. If you're considering these, I'd definitely recommend trying some before you buy. As always, your mileage may very. I just wanted to pass along my experience with them. Hope this helps, Brad Wanna kill these ads? We can help!
