Dry fire practice is a technique for beginners to get familiar with their gun in all aspects and exercising safety.
There are many that do not believe it is good for your gun to practice dry fire and if you are weary then you can purchase snap caps and get that into your training.
I have personally placed a target on my wall and continuously practice sighting and shooting my target for at least 15 minutes a day and this started from January. I have personally noted an improvement in my shooting and I definitely gained that from my practice.
