Ok.... so, it's inaccurate but at least it groups poorly.
In cases such as this, for me, it's best to start eliminating externals first. I'd do this by shooting only factory ammunition. Have shooters in whom you have confidence also fire it and have closely comparable pistols shot by the same folk on the same day as a sort of 'test-group'.
Call it a poor-man's socially gratifying Ransom Rest.
Try first for consistency of grouping and if that can be achieved - address 'accuracy' with all the known physics of the situation.
If NO ONE can group ANY ammunition consistently - It's a whole 'nother can of worms as to how you want to approach it and then, the actual value of the pistol as it sits becomes the single most important factor.
