50/50 right now - SIG SAUER Romeo-X Compact 1x24mm Enclosed Reflex Red Dot Sight

Mounted this on my Shield 9mm nice snug fit no issues untill about 50 rounds in and the Dot turned off for me. For a CCW sight, this made me suspect about to do for training and using it as an opportunity to go to Irons and continue. Next shot, it came back on. 100 rounds later happened again. This time, it was off for about two shots before it came back on. Confirmed the cap was tight, so I removed the cap to make sure nothing was in the way of the battery. Everything was fine, so it was reinstalled and continued and happened again. Contacted Sig that day, and they got with me the following day with warranty orders ready to go, and I shipped it that day. If this fixes the issue, i will change this to a 5 star not only for the sight bit for less than 24 hr respose and warranty set up. Yeah, I may have to wait 2-4 weeks to get it back, but dealing with some companies before it takes like 3 business days and back and forth to have something set up. Took 2 emails, customer service warranty department, TOP NOTCH! If your not using this with a SIG you will need to get your own screws. And not a big deal as I knew but you can not lock the brightness setting.
