The safety lever was annoying, because it is present but not foolproof. Now keep in mind, I like the idea of a manual safety, both for weapon retention and as a safety for me. (Even on a striker-fired pistol that doesn't "need" one.) I must admit, as I tested it there on the floor, it never failed to come off for me. But it is really tiny, and doesn't like to swipe on easily. For a 1911 guy, accustomed to positive snap! sounds and readily-available extended levers that fall very positively under the thumb, the Smith's safety just doesn't instill confidence. (The Kimber Solo, by contrast, has an excellent safety design.) Were I to invest in the platform, I would absolutely find a way to extend the lever just enough for positive engagement both ways. (And with that, we might really have something here.)
And of course I'll have to find another example on which I can examine the trigger, for pull quality, reset length and quality, etc. I'll admit I'm a bit leery of the hinged (Sigma style) trigger, but people seem to agree it doesn't seem to pose a breakage problem in actual use. As far as pull quality goes, I expect it will probably be pretty good--hell, most of the examples of this breed seem to have triggers better than the "revolver smooth" that I grew up with.
Will have to see. With an improved safety and confirmation of a good trigger, the piece might well get serious consideration as a competitor to the Kahr or the XD-S.
