Thank you. I updated as requested. I spoke with the President of CZ-USA today and she answered my questions concerning when she thought the company would be offering 550s in LH for 375 as I want to use it as the basis for a custom project.

Shall I assume from your response you would not buy an after market barrel but would rather be equally satisfied using a factory barrel? Also, the 550 in 375 comes in a 25" tube. Would that be too long for all round usage?

Thanks.
