My wife purchased a Sig 1911 .45 ACP in November 2015 with the Crimson Trace wrap around grips. It has worked fine until now. She turned it on and fired 5 shots and all seemed fine. She then handed me the gun and it no longer worked. I have gone through two sets of new batteries, but it still won't work. I contacted crimson trace and am awaiting a response on Monday. Yes the grip switch is turned on. Any Ideas?
