I think Glock nailed their goal with the G42. Why?
Well, when I attended an armorer recert class after the 42 had been released, they told us that Glock had decided to make the 42 due to their marketing studies. Basically, in the 3 years prior to them deciding to make the 42, they'd seen that the .380ACP was the hottest selling non-LE caliber ... and that the largest market segment for it was women shooters. Thus, they designed a .380 that was small enough to be convenient, but large enough to mitigate felt recoil and allow smaller hands to achieve a good grasp.
Turned out they hit a home run. While some grumbling was heard among the LE armorers - and questions about why not a 9mm or .40 in the same size (of course

) - some of the guys who were initially skeptical of the 42 seemed to warm up to it. While it was chambered in an old pocket pistol caliber that was sometimes described as "marginally adequate", it was still a handy option, especially with some of the newer .380 JHp ammo on the market.
The only reason I didn't buy one from the local Glock LE dealer at the time was that it was still too large for what I was looking for in a diminutive pocket-holster pistol. I compared the S&W Bodyguard 380 and the LCP ... and opted for the LCP. Eventually, a pair of them. No regrets. If I want something with more bullet weight and 'punch' than the 95-102gr .380's, I simply slip one of my J-frames into a front pocket (holster). The LCP offers me the ability to carry one in the occasional shorter and tighter front jeans pocket, though.
It helps that
I've found the LCP to be a surprisingly accurate and easy-to-shoot itty bitty .380 pistol. More enjoyable to shoot than my favored J's, comes to that (using +P in the J's). The S&W BG I tried on the range was just a bit too large, I didn't want/need the integral laser (first model didn't offer no-laser version), and the DAO trigger of the LCP offered a nicer stroke than the BG (especially the revised version of the original model). Almost made it feel "like cheating" compared to shooting my J's.
Bottom line, though? I think Glock sold a ton of the 42's, and it will continue to be a sleeper .... even if some guys don't want to admit they find it useful, practical for their concealed carry needs and decently accurate.
Now, if only something could be done about the cost of .380ACP.
