Never having had a DAO gun, I decided to take a chance with the P250 Compact. I've never shot a polymer gun by Sig (actually, don't know if they make any others now that I think of it). The modular design of this gun intrigued(s) me. I like the idea of the trigger mechanism having the serial number on it, and it just showing through a window in the frame. They sell different frames/barrels/slides so you can basically have 3 different versions of the same gun. Anyway, I picked it up today (got a great deal on it) and went to the range. I shot a couple other guns while I was there but mainly this one. Put 150 rounds through it. It feels good in the hand (grip, angle, balance, weight) and never malfunctioned. The build quality is probably the nicest I've seen on a polymer gun. If you've shot Glocks or XD/XDm's you've probably noticed how there's little wavy bits near the end of the barrel. Nothing like that with the P250 -- it's straight as an arrow. And while I know there's no functionality issue with it, it's just something I noticed. The trigger, being double action only, is different for me (obviously). Having only shot SA/DA before, I'm trying to be as objective as I can. I honestly think this thing has great potential. It shoots really nicely. The trigger pull is super smooth but there's no break like I'm use to -- must be a function of DOA triggers. I started getting forearm pump putting mag after mag through it. The pull is only 5 or 5.5 lbs, but doing it 150 times started getting tiresome. Seems like this would make for an awesome carry weapon or nightstand gun. You pull the trigger, it goes bang. Repeat as necessary. Out of the box it has an ambidextrous slide release and the mag eject can be quickly changed to left-handed use. And speaking of boxes, this was the most "no frills" packaging I've ever seen. It was a box with two pieces of foam sandwiching the gun in a plastic bag -- not even form fitting. There was also a lock and one mag.
