Yes, your KST1000 can be used for dryfire or airsoft training. You will have to tailor your sensitivity settings for your exact weapon. If your gun is particularly quiet, this can be challenging. First thing is to adjust the sensitivity to pick up your weapon. If it is loud, you may be able to have the KST1000 relatively far away. If not, it may be helpful to position the timer close to where the weapon will be fired. Depending on your weapon system and accessories, the timer will also likely hear other sounds. This can include racking a slide or drawing from a holster.
