As a public range part-time RO several years ago, I had a number of poor results with KelTec .32's and .380's. Failure to feed after one fired and ftf the first time were the too frequent in older units for me to ever depend on one. Over seven years ago, I had ftf problems with my two AMT DAO .45 ACP Backups one day at the range. They were traded in for both a new 696 and new 296 before the day was out. The 296 rode in an OWB holster - infrequently - until R. Mika made me a pocket holster, in which it fits 3/4 of my pants front pockets. Over three years ago, I added a 642 - and another Mika pocket holster. It rides in any of my pants front pockets - and is my 24/7 carry now.
The 296 has a round count over 2,300 now - over 1k of CCI Blazer 200gr Gold Dots. I quit using them years ago due one splitting in my 696. I switched to homebrews in Starline brass with the same Speer bullets - then to Georgia Arms similar loadings in brass, which I still enjoy using today. The 642 carries Remington R38S12 158gr LHPSWC +P's - and I shot many from it before discovering GA Arms similar reloads. It's seen many hundreds of them over the years - and anything else in a .38 Special case, wimpy to +P. I even shot the SPC plates - many times - with it and my wimpy 125gr JHP plate pingers. It was fun... until I had an epiphany...
These lite-weights, both the 642 Airweight and the the 296 AirLite Ti, are highly capable of more range time than I have given them. Neither is 'fun' to shoot - their low mass and small grips, carry assignment requirements, make shooting them not so much fun. I have a 4" 64, bought at a great price as a security guard trade-in to be a house gun, that is really fun to plink with whether fed with wimpy or +P rounds. The epiphany? The lite weights are for carry! Sure, I'll continue to shoot them - aperiodically. I'll likely cycle their ammo through other guns, occasionally, to keep 'fresh' ammo - but regular plinking is over for these guys. The 642 gets the nod for 24/7 carry - and has some edge wear apparent now. The 296 is a bedside gun now - and still looks new. Both are broken-in - but tight.
Sure, you probably could never shoot a 642 'to pieces'. I have a LEO friend who carries what I thought was a 642 on his ankle as a BUG. I was wrong... it's a very well-worn 442 - the finish is gone. He knows that S&W would likely refinish it gratis - he just can't do without it for the two weeks that might take. It is still tight, too... just ugly as sin! Remember, that lifetime warranty S&W has - it's real - and an 800# call will get you a pre-paid FEDEX label to return it, too.
My advice has, for years, been to make a 442/642 your first revolver - followed quickly by a used 10 or 64 for a house/car/plinker. Your carry piece must be a 'convenient' carry - sitting at home does you no good when Mr. BG accosts you in the grocery store's parking lot. Sure, the home defender can share the same +P .38 ammo with the carry gun when in defender mode - but can launch the cheapest .38s you can find for fun. Once a bottom-feeder type, I am now 'all revolvers'. My bias is heavy towards the revolver... what do you expect - it's a revolver forum! YMMV.
