AccurateWorked fine rotated it several times in the chamber with no noticeable change in the point of aim on the laser.

AFTER I adjusted my sights, I realized that the laser is askew. If you spin the laser in the cylinder, the dot wanders all over the place. Don't buy this item, QC is completely lacking.

This thing proved to be pretty much worthless. First, it's nowhere near accurate. If I'd actually calibrated my pistol sights in accordance with this thing, I not have even hit the target, much less a bull's eye. Further, the batteries have no shelf life and ran down after only a couple of months -- and that was after they were taken out of the device for storage. That would not be such a big deal except that I have yet to find replacements anywhere.

Worked like a charm, I love these because you can get 90% sighted before ever going to the range, then just make the fine adjustments.

While the idea of laser technology makes us think we are in the 21st Century, the laser alignment of the unit I received required that I apply stone age physics to it in order to try to center the laser beam within the casing ID... an approximation process on which I am still trying to improve. My guess is that buyers will find these tools hit or miss on their internal, factory-set alignment. Do NOT make the same mistake I did, i.e. do NOT throw away your packaging until after you are 100% satisfied with how your unit performs. This 38/357 bore laser that I got is very unpredictable, and especially since I dropped it once. OUCH! Now it works erratically. Some opinions and write-ups I've read about laser bore sighting make note that the user also needs to rotate the laser tool 90-120 degrees several times while sighting ones gun, in order to discover just how much deviation from center is inherent to that particular laser. After trying this unit, and the 7.62x54 unit, I'm inclined to agree with the old timers who say to pull the bolt out of your gun and eyeball the target, while your gun is in a snug rest or vise. However, lever actions and a lot of semi-automatics do not lend themselves to that technique.The first test out of the package (once batteries are installed and the laser is lit) should be to place the unit on a flat surface and gently roll it so that it describes a circle or portion thereof. You might notice that the laser seems to wobble as it rolls, which may or may not mean that the laser itself is off center. Double-check your suspicions by holding the unit facing partially toward you (but do NOT look into the laser!!). Holding the unit at an angle partially toward you, slowly turn the whole thing around its longitudinal axis as you watch the ID to see if the laser light uniformly reflects off the ID wall of the unit. IF the laser light seems dull as reflects off the ID wall, then your unit is probably centered fairly uniformly. IF, on the other hand, you see the laser light seem to get duller and brighter as you rotate the unit around that axis, then it is almost guaranteed that the laser is NOT centered within the ID of that piece in your hand. Trying to center a defective unit can damage it, so send back the bad ones.Having already tried laser bore sights in a couple of calibers, I'm leaning toward one of the more mechanically oriented types of sighting mechanisms, or else save the money and just shoot a couple of extra rounds downrange to perform the same function. The nice thing about point and shoot is that you can definitely hit the broad side of a barn at 25, 50, or 100 feet and then make corrections from there. Don't want to walk to the barn to look for the holes and make your corrections? Then keep a good pair of binoculars handy and save a few extra steps..

BACKGROUNDI find sighting with chamber loaded with a specific caliber boresighter to be the most accurate, for me. It leads to less variation, for the price. I have Colt Pythons and Smith and Wesson Model 627 8 Round 357 Magnum revolvers with adjustable sights. I prefer to sight for 25 yards for all combat pistols. This system works very well for me. It at least gets me onto paper.USEJust put the batteries into the compartment and close the boresighter. Ensure that the laser doesn't aim towards your eyes and do this with an unloaded pistol. Rotate the barrel to where the main chamber is and get ready to sight your pistol. Visibility is great out to 25 yards. Empty the batteries when you're done. There is no power switch.CONCLUSIONHighly recommended.
