I've got an Elite and an Elite II, the main differences are
Elites have the heavier Brigadier slide, helps with recoil and longevity.
Elites have Skeletonized Hammers, Elite is more skeletonized than Elite II, Elite II has the "d" hammer spring and a factory trigger job right out of the box.
Elites have dovetailed sights front and back, Elite has 3-dot, Elite II has Novak.
Elite have 4.7" Barrels instead of the 4.9. Elite II barrel is Target Crowned for better accuracy.
Elites are G models only, no manual saftey, just a decocker, Over on the BerettaForum we call em "G" thangs
Elite has vertically groved Front and Back straps
Elite II has Checkered Front and Back straps
Here's the kicker.
Elite IA
Vertec Frame, it has an Rail and Strait grip frame( similar to a 1911), instead of the standard Beretta rounded grip frame, everything else is the same as Elite II.
I purchased my Elite in .40cal for 600.00, LNIB, I got my Elite II in 9mm for 700.00 and it was NIB. If you search on GunBroker or any of the other sights, and even check out the classifieds on BerettaForum.net, you can usually find excellent condition examples for sale for around those prices.
And just for the record, I love both on these pistols, they never fail to operate as intended and they shoot like a dream. I keep them well maintained and feed them regularly to the tune of 250 rounds each per range trip.
And yeah, I've located a NIB Elite IA and I will be adding that to my collection as well.
Personally, if a Beretta feels great in your hands, you can't go wrong with any of the availible models, Even the new 90-two if you like it. When it comes
right down to it, it's not about what myself or anyone else on any of these forums thinks, it about what you like and what your comfortable with, it's your money, time, and effort.
