Just wondering if anyone else is having problems with their,s. I replaced my battery about 2 weeks ago when the sight went dim suddenly. I checked the battery and it was less than 3 volts so replaced it and moved on. I have done some dry firing but not to much. Anyway it went dim at the range today so again I changed it out as I carry a spare with me. After approximately another 30 or 40 rounds she went dim again. Checked both battery's at home one 3volts the other over 3 volts. Anybody else have this happen? I am now wondering what sigs turn around time is.
