I came across an inexpensive at home firearm laser trainer that I bought to use as an instruction aid for the Basic Pistol Class dry firing exercises. This product is an inexpensive system that really gives you the opportunity to practice dry firing exercises at home as well as be able to safely familiarize yourself with effectively training on de-holstering your firearm as you study for your CCW license.
