Just bought a Glock 42 and can't wait to shoot it. Initial impressions are very positive as far as being concealable. Fits in my pocket very well in a Sticky pocket holster and I picked up a Blade-Tech Klipt IWB holster and it is a great fit and very close to the body with such a slim pistol. Will report back as I spend time at the range with it. Read and watched enough reviews that I'm fine with it being a .380. This is meeting a special need in my collection.
