Kermit,
For me, the answer is yes. For you, well... it sorta depends on what you're looking for.
The difference in function and accuracy is virtually nill.
For the approx $250 bump in price you get:
Unique combinations unavailable elsewhere, sights, barrel lengths or contours, grips, finishes, etc.
Higher resale value.
Collectability in many models.
A whippy case.
Good Luck...
Joe
