I would bet it shoots as tight as any auto at any price by any maker, I do not know, but I would take that bet... gun to gun..
I would like to know what the test target looks like as well..
you mentioned Ken O'Neill's partridge front sight.. I am interested in that, too.. but I will be holstering my rig when I get it in monday... it is at the FFL dealers and all alone and needs me... I like the octogan barrel too and just saw one on an old western movie : Lee van Cleef had one while Clint had a more normal looking 45 colt... I liked it then too.
take care and show up those other guys once you practice with it a bit... but watch the man with one gun as he likely knows how to use it.. LOL
it is great to be alive and be a handgun shooter....
