I have an i-target. I use it with a SAO Sig P220. Its easy to just cock the hammer back and pull the trigger again. I imagine a striker fire pistol would get annoying racking the slide over and over. I haven't used it in a while, but they wanted more money to download a version that has a timed unholster and fire drill. The sled and target is kinda flimsy.
I dont have one of these, but to make it a little less of a pain with a striker fired, I took a snap cap and ground off the rim, then used a plastic insert from Mantis that prevent the empty mag lock back. So the snap cap will not eject, and the slide will not lock back. Still have to rack it.
