Yeah, I decided to experiment with the short and slim version. Even though it's just listed for the P30SK, it absolutely fits the full size P30. I tend to have a really aggressive thumbs forward grip. Although I haven't had as big of an issue with premature lockback or failure to lock open on the P30 as I do with Glocks, I've had it happen a bit. So far, this release has worked just fine. It takes just a bit more focus and deliberate motion to consistently hit it, but it hasn't been a big deal so far.
