My first gun was a Glock 17, but alas, she was not my first love. I bought her strictly for home defense so it was kinda like taking your sister to the prom - she fits the bill, but no romance at all. Then I picked up a S&W Sigma 380 for concealed carry, an ugly little gun with a harsh kiss and a serious weight distribution problem (she must have been retaining iron).
However, my first TRUE love, the one I wanted but didn't need, was a S&W 686 4" barrel. She is sweet, and I treat her gently. Over time she has supplanted by my newest love, my Glock 23 with night sights. She feels good in the hand and is feisty enough to be exciting.
