Welcome to CPF (cue
B@rt's fun pic)!
As to your question, I own the original 8X, as well as the newer 8AX and 8NX ... my preference is the original.
I find the prefocused hotspot tighter w/ the 8X than with the AX or NX.
The body is slimmer, which is more comfortable in the hand for me; opinions may vary.
The newer models, the AX in particular, look more "tactical" than the 8X.
I have been able to find more/better holster options for the 8X than with the AX or NX.
FYI, the 8X models were selling on closeout at rock bottom prices last year from some company whose name escapes me at this time. You might be able to find a good price on Ebay or thereabouts. /ubbthreads/images/graemlins/confused.gif
