Thanks.
I think I'll just go the CZ75b route. I didn't like the LPA adjustable sights w/ 2 dots as much as the plain black competition rear sights. Since I don't have use for the ambi features and can probably have similar trigger jobs performed on either unit, I think it will be much more practical to spend the extra $140 on other parts (i.e. FO front & comp rear sights, springs and mags).
I also have spare slide stops for the Shadow w/c I believe will fit the 75b, so I'll be saving on that too. I guess the only change would be the FP parts. Is it advisable to get spares for all FP parts (i.e. lever and block) or just the springs for the lever and block?
@soulfixinman, being a lefty, I think you might be better off w/ the 85c, OTOH, unless you use the left hand side to release the slide stop... and I'm not sure if the 85c allows switching the mag release to the right side.... unless again, you prefer releasing the mag from the left side.
Should you go with the Competition rear sight, I'm not sure if you should get the regular one or the one for the Shadow. Since the rear portion of the 85c slide is recessed, I think you would go w/ the Shadow Comp. rear sight but Angus could confirm this.
