After reading some of the problems people were having I was a little scared to buy one of the first production runs of this gun, so I waited.
I just picked up one of these with a manufacture date of mid-February this year (2013). I took it to the range with everything from 115 grain Hornady Critical Defense to 124 grain reloads and ran through 125 rounds without a hiccup.
Recoil is much lighter than I expected, especially for a 16 gram near-pocket tiny pistol. And despite its diminutive size, the extended magazine allows my XL-size hands to get all fingers on the grip.
The trigger is a bit heavy @ just over 8 lbs initially but has lightened up after one round of shooting and now shows 7.5 lbs on my Lyman scale. On the plus side, it's very crisp, with very little take-up and no creep. Reset is also fairly short; extremely short when compared to its DA competitors.
Sights are awesome SIGLITEs and were spot-on accurate right out of the box, with groupings just over 2" @ 15 yards unsupported. Not a great grouping, but this is a TINY pistol.
Build quality is very nice, and takedown is not that bad, but compressing the recoil spring can be a little challenging. Perhaps I'll get better with more practice.
Overall I'm very happy with this purchase and recommend you find one you can rent to give it a try. For a personal protection gun, it's very good...make that very, very good.
I'd rate it at 4.5 stars if that were an option, but it's not, so I'm rounding up. Good job Sig!
