The seac has a groove for the trigger pin which blocks the inner barrel and allows you to tighten a lot more

I think its the omer handle too, and when i have loaded it to 32bar the gap is a bit too much :-)

What i dont understand is that my friend has the mamba 110 magnum, and there is no gap. It may be the reducer piece between the handle and the barrel

I will try with a mares or cressi handle see what happens
