Hmmm... looking interesting...
I can't stand a tan holster against a black belt, and all my belts are black... well you see where this is going! After drying much longer than I actually had patience for, I dug through my shelves and found a bottle of Tandy MIDNIGHT BLACK leather dye...
On with the science experiment.
I applied the dye and allowed to dry... I had to reapply some areas as the leather did not pull the dye in as well. I had used a scotch brite pad to rough up the BODY side of the holster and was not as agressive on the belt side. The dye took well and the results are here..
Still slightly wet..
I let the holster dry a couple of days as I did not have any leather finish (acrylic sealer to prevent color bleed). Picked up the sealer at HOBBY LOBBY and got back to work...
After the sealer dried and was ready to trial...
And after a full day in the belt...no black on the shirt...

I hope it stays that way!!!
AND YOU ALL THOUGHT I WAS CRAZY.... well maybe just a little....
And for LOU, I promise not to pass this on to sombody else...
Hope you all enjoyed the long winded experiment with holster modification. What I woud say is that this holster was very close to fitting, but not quite. The controls are different on the 945-40 than the 4616. Enough so that I do not believe a 4516 holster will work, and I have yet to find a holster maker that has a blank for this gun, so I gave it a shot. I do not know if it will hold up, but currently the gun fits nice, the pull is slightly looser than a purchased holster from Alessi, but the holster has been through the ringer, literally.
Cheers and good shooting...
