I'm always reluctant to respond to questions that I don't have a pretty solid answer for myself and many others are the same. In my own opinion, worth absolutely nothing, I'd think it would be ok. The issue with polygonal rifling is lead. The polymer coating eliminates leading so it makes sense it would work.
Glock especially says no lead, could be catastrophic. But I've heard of several that shoot lead regularly. I tried to make them understand as the armorer instructor pointed out, you might have 500 with no issue and 501 blows up.
Around here we can't shoot lead anymore anyhow which sucks as I got a bunch of 45 Colt with lead bullets. Have to find an outdoor range or pit to shoot at. Those are getting harder and harder to find too.
