Another thought, would short stroking the gun via the use of an extended latch rod solve the issue? Less travel before trigger engagement meaning more room to move?

On guns that are near coil bind or that have the piston skirt hitting the rear guide flange just upon cocking, yes. The longer rod latches up before the spring goes coilbound or the skirt gets near the flange. Problem is, some short stroke guns still don't set the safety easily. The problem is much rarer in the short stroke than the MarkIII stroke guns.
It's worth a thought then. Think the issue I have is the piston has been customized, so I don't know if the dimensions are standard or not. I took the custom guide out and fitted a stock top hat and guide and it wouldn't cock, tried the original guide with a slip washer instead of a top hat, still wouldn't cock. Reinstall the custom guide with no washer, cocked again. Also appear to have sorted the safety by adding a little extra trigger tension via the screw under the guard, only got 15 shots or so off but set every time with a positive stroke, but not yanking it.
Tried various configurations of washers, guides, top hats etc in between, but the increase in pull weight is the only difference between when I started and when I finished. Literally about a quarter turn
