I se the cz custome guts and have zero issues. But then again I have the cz custome base pads. I'm sure they'd work in the Taylor one as long as there's no lip to catch on.
I emailed them and they confirmed it i signed up to their mailing list. I currently have a CZ TSO and i love it but my 320 just feels better in my hand and points more natural so i want to give it a go!
I'm roughly 7k rounds into mine and no issues. Did bent the ejector tab once though user error. Don't slam a mag in with aftermarket bad pads and slide locked open!
