I handled one today at a local gun shop. I wasn't impressed. It's cute and all but I would never buy one myself. For the money, I'd rather have a Bersa Thunder 380+. 15+1 capacity, much more comfortable grip and a much more attractive price.
I've owned a couple Glocks previously, and while good pistols I never cared for their ergonomics. That said as soon as I handled a Glock 42 and my LGS I loved the feel of it. True it's larger than a LCP but it's also a lot more comfortable to fire. This was a blue label gun priced at $350 so I bought it immediately. I think Glock hit a home rum with this model and will sell a ton of them.
