First post on XS 24/7 Big Dot

If you need a fast sight for defense carry and want it to work at night and at daylight, then this is the one. Easy to install, very quick to align, compact design. The only downside is, you can't balance a penny on the front sight ;f

I have had the sight for about a year on my Glock 32 and have enjoyed using it. However, last week the rear sight died. I have contacted the company and am waiting for a reply.

They use trijicon inserts. Is a bit soon for them to die.

I have the Big Dot Tritium Express (front only) I got them about a month before the 24/7 came out. Had them for a couple years, I like them.
