I spoke of my own scrubby gun collection, which includes various and assorted plain old ordinary Glocks, XDs, Ruger 22/45s, Marlins, a Remington or two..........
Most bought used. Nuthin' very special. And also a Jiminez JA-22. (Do NOT let this latter fact get out to the rest of the forum. Way, way too embarrassing. That JA-22 is about as scrubby as it gets.)
Now, Howard Buffet's collection probably has high-end Kimbers, STIs, Perazzis, Krieghoffs, Merkels, etc., etc.
As it happens, Mr. Buffet's weapons qualifications appear to be outstanding. All 76 of them. After all, he is the sheriff.
