how reliable are these guns really? I love the idea of having a really thin pocket gun for summer carry when mt 442 wont work(my usual summer carry gun) but I wont keep a weapon I cant count on and I cant count on one that has issues. also is the 9mm version even close to as small. just looking for the most slim pocket gun I can carry when im in shorts and t-shirt or no shirt. (always like to have a weapon on me) Also if you like another super thin reliable auto Im all ears.
