Does anyone make a Glock-compatible 9mm lower that doesn't have the triggerguard already "built-in?"

A buddy of mine borrowed my R9 (Runner Runner Guns/New Frontier/JoBob Spartan) lower for a 3-Gun shoot this weekend (ran flawlessly!), and noted the triggerguard was digging into his hand.  After shooting mine, he wants to build his own, but would rather have a traditional triggerguard setup. Everything I've seen so far has the enclosed triggerguard, although the QC10 lower looks the most "conventional."

Any ideas?

I searched Google images for Glock ar lower and came across this:

A local company to me Black Creek Precision is finalizing their forged glock dedicated lower. Last I heard was end of May...  I am waiting on these myself. Check their Facebook page for updates and pictures.

I have been waiting for this one also, i came across it a while back and i like Forged lowers over billet. Does Black Creek Precision have a good reputation?

From what I hear they do. I personally don't own any of their products but I have researched them. They are right down the street from my work, so I want to give them a shot myself.
