Not sure this counts, but I traded my Sig SP2022 in towards a M&P9c with Trijicon HD night sights. Essentially, I switched a bulky full-size pistol, that was very difficult for me to conceal in warm conditions without looking conspicuous, for a small, compact pistol that can be easily concealed at the waist, or even on my ankle. Won't be sacrificing capacity, either. Standard mag is 12-rd, which is 3 rounds fewer than the Sig's 15 rd capacity, but the full size magazine (which also fits into the compact) holds 17 rds. So about even when carrying, and 2 extra rounds at home.
Next kicker will be to get enough range time to be comfortable with it. I've done enough dry firing to be pretty sure I'm getting an upgraded trigger/spring kit from ATEi.
