I called CT about what size for my grips as I bought the gun with grips previously installed.
The women simply said ,"it's easier if you give me your address and I will send some" thank you I said.....then she said " oh and when you get them don't keep all of them in on spot,ESPECIALLY IN YOUR RANGE BAG"
Few days later I received a envelope with 15 tiny little wrenches...3 bags of 5.
It's a fact no matter what you have for tools eventually you won't have what you need.
I got a pretty good assortment of various bits for work.....but I did not have the tiny triple square bit that needs to be on a long screwdriver smaller than 1/4" shank ........wtf I say.
Looked it up......sure as shit special service tool number 27456 or some shit......oh boy.
