Wanted to pass on information about the Crimson Trace Laserguard (Model LG-469) on the XDs-9 mm. I range-tested the above configuration today, both the pistol and the laser are new. I mounted the CT Lasergaurd, and everything looked tight and snug. The screws were NOT loose. After a few shots, using at the laser dot, the POI started migrating! Upon inspection, daylight had appeared between the lasergaurd and the undersurface of the barrel section in front of the triggerguard. The laser device has a top ridge which was is supposed to engage a slot in the railed section of the foregun, but it was visibly separating from the picatinny groove. It looked like it was about to slip out of the groove. Furthermore, every second or third shot, the laser dot would simply fail to appear, despite direct pushing of the activation button, and would only reappear after "rattling" and banging on the side of the pistol a few times. I removed the lasergaurd, wiped off the battery with a clean dry cloth, reinstalled it all carefully (per manufacturer's instructions), and it looked snug, no daylight. I tried another couple mags, and the same problem recurred. Shooting the gun looking at only the iron sights was fine. The groups were nice. No misfeeds, no jams (approx. 100 rounds). Working with the irons sights is NO problem. I called Crimson Trace customer support, and the rep informed me that I was not the first to report the issue. Crimson Trace has discovered that their sight (LG-469), which was designed for the XDS .45ACP, is not fitting the XDs-9 in the precise same manner. They are attributing this to some small difference in the profile of the XDs-9. Regarding the dot loss, the CT rep stated there was a battery issue which was causing the intermittent loss of the dot, and they are shipping me a new battery. The CT rep reassured me that I would be taken care of. I had registered my Laserguard (thank goodness), so I am now on their list to ship out the "fixed" sight (sometime in September 2013). I will provide a followup next month, to update on whether I actually receive the "fixed" Laserguard, and with a range report, if it is shipped.
