I recently emailed Tristar with a couple questions about the CZ clone lines. One of the answers I received back from Tristar was that all the slides were cast, rather than forged. This seemed strange to me since at least one of their models has a forged steel frame (C100 in 40sw).
I emailed Canik directly with a few questions and here are the answers:
All slides are forged parts.
Barrels are not cold hammer forged.
The C100 uses a 7075 T6 aluminum frame. (I was already pretty sure about this since the L120 is listed as using 7075 T6 on their website)
I responded by asking whether the C100 is forged 7075 or cast and I am waiting for their reply.
