They are fairly snappy shooters, even more so than comparably sized pistols like the Shield. Could be because the grip is tiny. The hype was more about the 10rd capacity in a microcompact than it was about the gun being a great shooter or aesthetic work of art. I mean, this entire class is just about EDC concealment over all else, so to get 10rds out of a gun that is smaller that other brand's 6+1 is kind of a miracle.
The build quality of mine is great. I don't think it feels cheap, unless you really squeeze the grip without a mag in it (it flexes). The slide is machined great and has almost no wobble on the rails, yet racks easy enough. Mags are metal and drop free. Sig night sights are super bright. Stippling is a little aggressive, but not terrible.
