Hey 1775usmarine!
I thought of you when I was trying to find this thread!
Follow up: I just tried both & they fit perfectly for me: nice & tight & the thumb strap connects (snaps) good.
I am pleased!
I got an OWB holster with it so I'm set.
Getting ready to stop at a friend house in Shelbyville & pick up a 22 pistol & rifle to shoot (the pistol I bought last night for him), just for fun.
So, I got my new 6964 & friend's 2 guns to shoot & a couple more of mine, so it looks like a 3-4 range visit, which is good b/c my wife is in work mode & I have to hide.
I figured you'd know where the gun came from since you keep your eye on anything SW 3rd gen.
Full report with my boring range pics will ensue.
I always call S&W and try to get manufacturer date since I like knowing how old the ones I get are, especially those that are in excellent condition.
