Phil,
Thanks for the pictures and the details. Your SP-01 is SICK - I hope it works out well for you. Sent you a PM, btw. Couple more questions.... What are you doing for magazines? SP-01/modded factory 25rd deals? Whatd you do to get that stippling texture on there? MarineTex or equivalent?
The EFK info is mucho helpful. Looks like there is the source for extended barrels. Seems to be a multitude of different routes to go here, but I'm a fan of options. I recently ended up with a 9mm upper, and I'm looking at what all would be required to fit it to my TS lower a la Angus' CTS concepts he was showing off a while back. Already have magazines/holsters/etc for it, so that might be a natural route. All I *think* I would need would be a barrel (which thanks to you is now found), and a comp (Which Venry could make), and the requisite fitting the slide/cutting for a FastFire.
Lots of helpful info in this thread pertaining to all things CZ open, so I changed the name for easier searching. Anyone have any other open class experience/ideas, feel free to let them be known!
