I cant supply photos because the only ones we have are of the prototypes we built in January. A good photo of that frame is on our home page www.lonewolfdist.com
The button on the back strap is an option. If you decide to get one of our integral lasers you would use a back strap with a button to activate the laser.
All the Timberwolf frames will have to be transferred to a FFL. They will be logged in as "multi cal" good for use as a 17,17L,22,24,31,34,35,37 (9/40/357/45GAP)
Unfortunately April 1st delivery is right out. The way we are running now I suspect the end of April. I will provide a delivery update mid April or sooner.
