Looks like an interesting subcompact offering in the P series.
I'd still give it at least a year to identify and resolve any teething pains that might surface. (Significantly shrinking even an established & tested design can sometimes result in an occasional unexpected issue when the guns get out in the hands of regular owners/shooters.
As much as I like a nicely machined smallish metal-framed pistol, I wouldn't be surprised if the cost of the time required for the CNC machine prices the little gun a little high (compared to plastic guns).
I'd like Sig to have a well received model with this latest offering ... and at some point later on I'd be tempted to look at a TDA (DA/SA) variation.
Depends on the price, though.
As much as I liked the S&W Chiefs Special series, the 3913 & the 4040PD, the cost of machining the frames (and the Scandium aluminum frame used in the 4040) simply priced them out of interest when it came to the folks comparing them against plastic guns.
If this little model runs in the $1K range, it might have limited appeal for folks in this economy. Dunno.
Time will tell.
Nice looking little subcompact, though.
