Kinda funny - the Beretta 92 is hitting a much needed resurgence of popularity these days. 10 years ago, there were only a few folks using any kinda of 92 (Elite if you could find them, or 92FS/92G models) in any of the action shooting sports.
The base template for all the guns is really similar - the biggest differences are in the vertec vs humped grip, slides with dovetails or integral sights, or the really different 92XPerf which has safeties a different trigger feel and has a steel frame vs alloy.
I've been shooting a LTT RDO for most of the season trying to learn the Red Dot. I won IDPA Nationals (ESP) with a lightly tuned LTT. I really don't mind the "humped" alloy frame...
You can't really go wrong with any 92 - but maybe try out the grip profiles/sight combinations...
