That's the biggest problem with my 4" Security Six. Boringly accurate; boringly reliable. It even sends wadcutter target loads to the exact same Point of Aim as hot loaded 125gr JHPs...at 25 yards. The gun is totally boring.
I love boring and I LOVE Security Sixes. Owned a GP100 once. Like Strafer Gott said, it was a clunker in comparison. Only way I could like a GP100 is if I'd never shot a Security Six.
