Kahr recommends the slide release due mostly to all the complaints of jams on the first round.
If you sling shot properly IE: Don't girlyman it, do it briskly, rip it back and let it fly it will work. Many unconsciously ride the slide just a bit and they can be pretty unforgiving especially when new and tight.
