Ruger seems all over the place with their double-stack semi-auto pistol offerings lately. SR9, 9E, RAP, & now Security 9.
Honestly the SR9 was a very good design hampered only by its silly mag disconnect, LCI fin, and manual safety. It is an accurate, reliable, slim, and relatively ergonomic pistol that shoots very well. If Ruger would have just developed that pistol with features people actually want instead of those "features" they don't, they would probably have a very desirable pistol at this point.
