I've had some issues with mine. It went back to Colt twice. Satisfaction wasn't there. I have a call tag and need to get it shipped out again. This time the custom shop guys are interested in it, so maybe it will be gtg this time.
Main complaints with many of these XSE Colts seem to be the ambi safety or white dots falling out of the sights. I see a lot about them two issues. I'm replacing the stock sights of mine with Heine and I'm requesting Colt to replace the failed ambi with a single sided unit this time around. Most of my other issues with it is fitment issues. The grip safety isn't right, trigger, slide to frame after the last time back, The barrel to slide was the original issue, but they dinked with the slide to frame instead. I'm going to send money to checker the front strap, and since they are going to be filing away there, I'm requesting they touch up the sharp edge at the enhanced trigger guard. It cuts into a persons finger.
All and all it isn't a bad pistol, but inspect it well prior to purchase and if you can, pick from more than one.
