It is indeed a 6, I was planning to wait for a new 9 model with the american mag relaese until it came to the distributor and I saw that dealer cost was $3,700.00. The new models are really the "old" models Sig had shifted gears to make the ill fated PRO polymer models and has now realized the error of their ways and resumed production again. On the finish I have been through so many finishes and I have decided that for my regular needs Black T is the best finish for me, on my high round count shooters/practice pistols I plan to use brushed hard chrome.
The surplus models are fairly good but I tend to find more machine marks on them and I would definitely recommend swapping the springs out for Sig factory new models.
My next Sig will be the new P220 high cap model.
