1860 Pietta Army 44.
I read a real long wedge thread here. No mention of my issue.
My wedge (got the gun today, new, Cabelas) has a spring type lock on it.
To drive the wedge out, I had to hold the spring lock down. Not easy, but it did not defeat me.
I used a hammer to drive a Bic pen top in, under the wedge lock, holding it in the clear the frame position, then put a wood block on the wedge and banged it out with a hammer (on the wood).
It is one super tight wedge.
I saw a video online and he used his thumb fingernail to hold the lock down, and wiggles the wedge out by hand.
My gun will have to loosen up a lot before I can do that.
