The fair accuracy is not necessarily a bad thing for the gun's intended purpose. The were based on the original Colt design to function in the mud, crud, and blood. This was done, in part, through certain amounts of slop in the mechanism. That slop produces accuracy that is questionable for some folks, especially those of us who want a tight gun and never think we will be fighting in the mud. A Les Baer or comparable gun will likely not function under horrendously adverse conditions like your Systema is designed to do. On the really good side, depending on wear of the gun and how well it locks up, you might be able to find a good smith who can increase accuracy with a properly fitted bushing and barrel link. As Vickers noted, slop in the slide/frame fit is really inconsequential to accuracy in comparison to barrel to slide and barrel to frame fitting.
