Have a look: XS Sight System's 24/7 Big Dot

In my latest adventure I tested an XS Sight Systems 24/7 Big Dot sight for my Glock 22. Since the name of this product can be a mouthful, we’ll call the sights simply XS sights for the rest of the article. The bright tritium front and rear sights...

At the range, I started with some quick controlled pairs. At contact distances, the Big Dot covers the A zone. XS Sight Systems instructs the user to place the front dot on the target. I did, and all my shots were hits. Out to about 10 yards, this formula worked for me. The company also instructs shooters to align the target with the top of the dot for ranges at the 25 yard line and greater. I didn’t. I didn’t need to. I put the dot on the target as before and proceeded to keep all my offhand shots inside a 4-inch circle at 25 yards. Really, if anyone has a complaint that the entire front sight covers the target, he or she is shooting the wrong target. It is supposed to cover the target.

Full disclosure: My Glock 22 has a Lone Wolf .357 SIG barrel, which is a drop-in upgrade for this model. The other day I loaded it up with Load-X 124-grain rounds and proceeded to bench rest a 15-round magazine at 25 yards with all rounds touching. In other words, this gun will do anything we expect from a handgun. I like this barrel and I like options. (Note to iPad viewers: You will have the opportunity to see me fooling around with failure drills and controlled pairs using full velocity rounds in the September iPad issue of LET.

I think the best application for the sights is the one quality I rarely see mentioned or discussed. These sights give the shooter a serious edge in low light. First, the Big Dot is a mile wide silhouetted in the beam of my flashlight. Second, the huge V encourages the kind of shooting that will keep the officer in the fight: Both eyes open.

Here’s the bottom line: XS Sight Systems 24/7 Big Dot Sights are designed for engagements, not target shooting. I believe they will give officers a slight advantage with their duty gun.
