As expected, it’s a very quality product. Grip feels great and the stock is surprisingly sturdy. But the fact that it doesn’t come with a mag catch/release is annoying enough that I’m giving it 4 stars.

It took about five months to arrive from Switzerland, but the wait was well worth it. The FCU fits nice and tight and the stock locks securely. This compact style frame fits the 21-round magazines flush, so what's not to love? (Yes it does not come with a mag catch, but likely you already own a complete 320 so swapping it over shouldn't be too difficult if you know what you are doing.) All in all, this makes for a fantastic setup!

The grip module is around comparable to the P320 OEM grip. The grip panels feel roughly like skateboard tape in texture - won't rip up your hands and adds a bit of extra grip. The completely ridiculous part of this entire assembly is that it does not come with a magazine catch. It's a $300 grip module, and they skipped on a $15 part.
