UPDATE 2: The Sig's sear pin broke at the range last weekend. A light finger pull on the trigger can allow the hammer to fall to half-cock. This happened twice, and the second time the impact broke the sear pin. This seems abnormal - no 1911 I've owned has ever had this problem. Sig is sending a replacement pin at no charge. I will remember to pull the trigger more authoritatively to avoid the half-cock problem, although I don't think this should be necessary.

UPDATE: The Sig works acceptably now. I polished the extractor and extractor groove (very aggressively) and fired about 300 rounds. It is reliable enough to carry and shoots very well. It took several hours of gunsmithing to get it into shape though, which is not acceptable for a $740 pistol. The Diamondback now has feeding issues. Seems to be a cartridge-overall-length issue with some FMJ ammo. All JHP ammo I have tried feeds OK, but I need to do more testing because it hasn't been very many rounds.

ORIGINAL: Just got a Sig P938 and Diamondback DB9 today. The Sig is simply unusable. Very pretty, but it doesn't function. FTE (failure to extract) every other magazine or so. I'm not the only one reporting this problem. Did they test this thing at all? Also, the trigger might seem good compared to other pocket pistols but it's awful for the SAO 1911-derived action that it is. It feels like 10-12 pounds and is crunchy, with lots of creep. Even a little bit of effort finishing the sear and hammer could make it a great trigger, but Sig didn't bother to do it on this $700 pistol. I assume I'll have to spend a couple hours fixing the trigger once they get done making the extractor extract. I would love to be a beta tester for new guns, but not at my own expense!

The Diamondback DB9, on the other hand, is good. They seem to have spent their money on testing and engineering instead of finishing. Build quality is somewhere between Kel-Tec and Glock, and the function is too. Assuming it does as well with defensive ammo as it did with FMJ, I will be comfortable packing it. The sights are seriously misaligned though. Shooting from a rest, the point of impact is about 6" low and 2" left at 7 yards! The windage is adjustable, but the elevation is not. It's a rather annoying problem.
