I bought a new 296 & 696 1/03 - both new, but on closeout. The X96 family just didn't sell. Heck, S&W never was able to 'sell' .44 Specials in decent numbers. The 24/624, before the X96 by a bit, also didn't sell - and was dropped. The .44 Special revolvers were always 'enthusiasts' revolvers.
Of course, the X96 series has a built-in fault - the thin walled forcing cone. This is a design problem brought on by the thin frame front of the L-frame, designed just to allow a bit more meat in a .357 Magnum's forcing cone to prevent fc erosion/cracking when shooting lower weight/hyper velocity rounds. It was never meant to handle .44 Special, especially shooting Keith level, loads. My examples are fine - probably due to their long life enhancing wimpy loads. Another reason the barrels ran out early in the 696 is they were often slightly bulged from over-tightening.
If you really want to keep the 696, the 396NG barrel shroud/liner might be fitted - but that would look odd and likely be costly. I would opt for what I suggest is the best .44 Special revolver S&W makes - any X29 model - like a 629MG or 4" 629! Even a 4" 629, which weighs a whopping six ounces more than the 696, would be a great choice. I ridded myself of two 6.5" 24's, one a beautiful Heritage series, and replaced them with a 6" 629 some years back. I later replaced my 629MG with a 4" 629. The beauty of the 629 is that it is Keith level ready - it's a .44 Magnum! Also, the standard partial lug 4' 629 looks very traditional - and has a larger hammer & trigger, longer sight radius, and additional round capacity. Fitted with wood grips, it'll handle any .44 Russian or Special comfortably. Clean the chambers - and put on some .460/.500 Magnum Hogue monogrips, and it'll handle any standard Magnum load, too. Below you'll see my 696 and 4" 629 for comparison.
I would see if S&W would substitute a 4" 629 - even offer you one for a little difference. You'll be happier... believe me. I tried to wear out that 696 the first few years - then I replaced my MG with a regular 4" 629 - that's better - for me - YMMV.
