The single most accurate handgun I've ever owned was a 4" blued GP100. It would put 6 170 grain Sierra JHCs into a group too small to measure, around 0.2 to 0.25 inch center to center .. had to just estimate from how big a single hole was vs how big the group. It would do it over and over and over again. It was an educational gun .. showed me what I could do from a bench with iron sights, showed me that bigger groups are the gun / ammo, not my eyes or trigger finger.
Today, I'd probably go with a still NIB pre lock x86 (not too likely to find), then a GP-100, then a x86 with the lock in that order. I would have to throw the S&W M27 4" and Dan Wesson in there as well, maybe even a 5.5" barreled Redhawk.
Sorry to hear 'bout your Python's SA pull, I've only shot one and for me they are/were a dream gun. Based on feedback here on the Campfire, I wouldn't buy one of the new ones.
