Expert in .45

Hey gang, is there a “big box” store or even a mom and pop shop that I can get an expert in .45? I feel like I’ve looked everywhere. I got my first “proper” bonus and I’d like to treat myself. I already owned just about every gun under the sun, but I do not own any HK’s. I think the expert would be a perfect fit to my collection. I really appreciate the help here. When I say big box store, I mean I’m willing to pay MSRP, I’m not scouring the earth for a seal. At this point I’m just scouring the earth looking for the damn gun. Thanks in advance guys.
