Just an FYI, I shot my Kadet kit on my RAMI 9mm yesterday and it worked great, a little weird feeling but it functioned just fine. I even used the extended slide release from my SP-01 with the Kadet and that worked fine.
On a side note, where can I get some decently priced Kadet mags? Anything less than $20? Less than $25? I went through 400 rounds of .22lr yesterday with only two - 10 round Kadet mags.
