Have never had a 10 mm Witness, so no help....The wonder finish is a type of heat treatment finish, and as such, is super hard and durable.
I own a poly compact, that's very accurate, feels good in my hand, and is a complete POS.
Japle nailed it on Eaa customer service..
, I'm glad you have a 9mm that works.. I really wanted the Witness to work for me, as I like the way they feel in my hand, And I find they will outshoot about anything else I own
The Witness was the only series of pistols I ever owned, where I had a 100% failure ratio, out of four. Some people tho, have really good luck with them............ I was unlucky.....
