Get the edge in self-defense and a great training tool for trigger control drills! - Crimson Trace Laserguard Sight for Sig Sauer P238/938

FIRST let me say that no laser sight should ever take the place of learning and practicing good fundamental shooting skills using iron sights. Better yet, practice the rapid "point and shoot" technique that is the most likely real-world scenario to be encountered anyway. That said, the CT LaserGuard on my P938 is hands down the best, most reliable and instinctive laser sight on the market for quickly and accurately engaging threats. I've used many CT lasers on many firearms and never had one fail to operate and hold a perfect zero even after many many rounds down range. Invaluable as a training tool also! Have someone else load a mag for the shooter and replace a live round or two with a snap cap then shoot as normal. When the shooter gets to the dummy round in the string of fire, watching the movement of the laser dot will instantly and dramatically highlight any issues with anticipating recoil and/or trigger control.
I only gave it 4 stars because for me, I would like to have a master on/off switch and an external access battery compartment. I understand and generally agree with the KISS principle of the "always on" mode of the CT laser; however, from a tactical standpoint there may be times when you might not want to use a laser at all. Other than altering your normal shooting grip, the laser will always come on. For range work, the on/off switch would also be handy for saving battery life when practicing with iron sights, but a small piece of tape over the laser works ok too. The battery does last a LONG time, but when it is time for a new one you have to uninstall the laser from the pistol completely, change battery, then reinstall laser and re-verify your zero. Again, not a huge deal for me.
With the snappy recoil of the P938, the CT LaserGuard is a great addition for ensuring rapid, reliable, and very accurate follow up shots.
