Recently, I decided to try out this product, the Laserlyte Laser Training System. I ordered the target and the cartridges for both 9mm and .45 caliber pistols. This is really a great tool for dry fire practice! I can practice in any room of the house, and get immediate feedback. This is much more effective than dry fire alone. If you want to practice your fundamentals in the comfort of your own home, this is definitely worth considering. The initial investment is a little high, but compared to ammunition, it’s quite reasonable over the long run. Allows keep live ammunition in a separate room when practicing, and ALWAYS VERIFY THE GUN IS UNLOADED.
