Largely, yes. They're all the same "basic idea" of pistol. The small nuances do stack up and that's where the price becomes questionable... E.g. Anyone who buys a basic beater 92FS "trade-in" is going to spend $$ on the trigger kit, the rear sight, grips, extended magazine release and MecGar mags to make it competitive.
The alternative is to buy a new LTT and be pretty much there.
The 92XPerformance only seems different. Safeties, steel frame, etc. The reality is, tho, that it too feels much like an old Brig-slide Beretta Elite, E2, or G-SD. Once i shot it for a bit I forgot I was shooting the steel-framed "race gun"... It is still a falling-block Beretta 92...
