Sending one to @JCN would be a wise step. He’ll test the hell out of it, and tell you if you might need to dremel a bit here or there (sorta kidding, sorta not). Most importantly, we would trust his evaluation, and P-F is probably the most pro-SCD demographic in the country.
I don’t know if there’s much of a market, but once the gadget for the P10 has been perfected, I’ve read that the FN 509 is similar to Glocks and the P10 in not being fully tensioned.
