Well folks, I gotta thank you all. You teamed up on my question and answered all those nagging things I was trying to figure out.
-Barrels are interchangeable.
-Sounds like the flex tech stock can swap back and forth as well. To be honest, I was kinda thinking those stocks would be a nice addition to shooting comfort.
-Engraving is a non-issue for me as Im looking at function first, though I do admit to enjoying a little fleur now and again.
-The hammer ear switch-ability on the pro sounds interesting but I think an extension would serve me well if needed for scope clearance.
Much appreciated.
