The M11 bit is mostly marketing, it's not that similar to the military P228/M11, but I think it's a wonderful gun for what it is. Basically a 229 updated with some nice features (night sights and most especially the SRT). If you don't want a rail, I think it's probably the ideal 228/229 pattern gun in current-production.
I'm a fan, despite the bit of Exeter Sig marketing dust sprinkled on it.
