Works great - Crimson Trace Front Activation Green Lasergrip for 1911 Government/Commander

Was easy to install but I had a problem with sighting in. It appears the instructions have you turn the adjustments the wrong way. This was very strange but once it was solved sighting in was a snap. The adjusting screws are tiny and the wrench seems too flexible. I don't see a reason for it to be so long and the flex in the wrench is such that it is hard to make small adjustments. I assume this wrench is used on all products and is long for this reason. Otherwise it works great and the turn-off switch insures you won't drain the battery when it is stored away. My old eyes aren't too good for iron sights and this is a good alternative.
