Mine is the same as yours, also the rear of the slide is not flush with the frame. /this concerned me at first, however after cosulting with a fellow armorer it was determined to be the norm. After 500 or so rounds, it has performed with perfection. These have to be the best little packing guns in .45 caliber I have ever had the pleasure of owning. Accurate, and as much at home in a gun belt as it is in a pocket holster or a IWB.
Never try to explain yourself to stupid people, you're not the jackass whisperer
