Well, after hearing about the frequency of QC issues that seem to I ocurr with DD guns, I decided to actually sit down & look at mine (haven't had a lot of free time lately). Long story short, I regret not getting another Colt or BCM. The castle nut is not staked in any serious way, the safety detent spring was broken from the factory, the castle nut has some weird discoloration running down the side, the grip screw was almost impossible to remove & then reinstall (threads are prob fucked) again from the factory, & there is a noticeable gap between the trigger guard & grip.
Given how f***** up all these simple things are, I can only imagine how screwed this thing is internally and on a more technical level. I've sent an email w/pics to DD & their rep was pretty dismayed & said she didn't blame me for being upset. She offered to completely replace the gun if I sent it in (which I am).
I know this is completely my fault for accepting this thing, but frankly at the FFL I was in a huge hurry & did a quick look over with a basic function check. Hopefully they can sort this out.
