Question: Can I use this to bore sight my pistols
Document: I used this to help line up my laser sight on my Walther P99C 40 cal and it worked great. I also use it to practice trigger control on my P99C and on my P99 full sized 9mm. Works great on both of these pistols.
We use this indoors to keep sharp on sight picture and trigger control. Works great in 9mm and .380 pistols.
Works well in in pistols - particularly double/single action as there is no need to work the slide after every trigger pull. It is accurate in my pistols if you adjust the tension properly. Does not work well in my revolvers for some reason. It doesn't stay seated in the barrel (of my revolvers) properly which makes the laser inaccurate to the bore. Overall I have found it to be very usefull for dryfire practice with a pistol.
This is a high quality product but buyer beware you cannot make any  internal adjustments to the laser. With most guns it will shoot low---thats because there is some offset between the bore and the front and rear sight of the handgun. The degree of offset depends on the handgun used. IMO the ideal set up is to have the laser dot projected near or at the tip of the front sight when you pull the trigger.
This is a great aid to supplementing live-fire training. Since you can use your own firearm, you can really dial in the fundamentals without the expense of ammunition and range time. I find that using the Laserlyte just a few minutes two or three times a week has really helped me to improve my accuracy by allowing me to see the sight picture followed immediately by the shot placement without the distraction of blast and recoil.
This product works as stated.I use it on different pistols for practice.It is a lot cheaper than live ammo.
I bought this to use in both .45 ACP and 9mm pistols. It works pretty well by itself, as you can see where you "hit", and the laser stays on half a second or so, so you also see the path your follow-through creates--another benefit. With the Laserlyte laser target, though, the thing becomes really useful.
This is one of the two necessary options you need to use the LaserLyte target. The advantage of this over the other is that you can use it with various different caliber pistols. You simply adjust the base to the proper width, insert into the barrel (preferably with a snap cap in the chamber) and you're all set. At least, in theory.I originally posted a relatively positive review of this item.
I purchased this instead of Laserlyte's caliber specific cartridge because of the ability to use it in diffrent caliber pistols. After several days of use the laser often would not fire or would fire to dim to activate the target or even be seen. I changed the batteries muliple times with no improvment. I broke down and bought the caliber specific laser cartridge from Laserlyte and so far have had to problems. Dont waste your money on this one. Get the caliber for the gun you intend to train with.
Great for target practce at home. Saves ammo and sharpens your skill level. I woul recomend this sight to all shooters, serious or hobbiests.
