I’m not into strap locks - have never needed them with PRS stock buttons.
I’ve found two firms making straps that I think compliment my PS models. I wanted simple, clean design, finely made straps with high end leathers, and because I’m a klutz, no metal parts to bang against the guitar!
The German company Richter makes a strap called the Springbreak that uses premium nappa leather finished to a very soft hand, but the inner leather layers are nice and firm. The thing has kind of a BMW/Porsche/Mercedes quality and design simplicity.
There’s memory foam padding inside, so the strap is extremely comfortable, and has an ingenious system that lets you customize the length beyond most straps. On request for no charge, Richter will cut the buttonhole slit 1” to easily fit the PRS strap button. I’ve had two for probably 4 years, they’re elegant, wear like iron, and aren’t all that expensive. There isn’t any metal on the strap to bang against your guitar on this model. The leather on the ends is layered and firm enough that the buttonholes don’t stretch out and get too loose.

I’ve also found a strap by the UK company Heistercamp that’s made from those wonderfully thick and aromatic pull-up leathers that you usually find only on high end English briefcases, gun cases, etc. It’s so nice I had to get one for my son. The quality of the leather and workmanship kind of blew my mind.
While the one I have is too thick for the stock strap button (I use it with my bass), they now offer straps made from what they call “super soft” leather that will fit. They will also custom-cut the buttonhole length (email them on their contact email and they’ll tell you how). They have a model that doesn’t have metal on it. If you want to keep the strap button stock be sure to order the super-soft, and not the pull-up leather.
