I own the LCP & LCP2 and while the original LCP has been reliable, I've had trouble w/the mag popping out (I'm a leftie) while in my pocket holster (same problem w/the S&W Bodyguard). The LCP2 has not been as reliable so it would seem there is a point of diminishing return when it comes to light weight & small size. My J frames have never failed me in over 50 years of carrying them.
