I just bought a CZ TT-9 off of Gunbroker. Paid $230 for it, which isn't bad. I had been missing my Springfield P9, that I had sold to my father for a lack of magazines.
I'm really liking the ejection-port locking on the TT-9, and availability of magazines through Tangfoglio. I'm thinking about picking up a Witness steel frame, and seeing if the TT-9 slide and barrel will fit.
Has anyone swapped slides and barrels between the Witness polymer and steel-framed Witness?
