Accordingly, a live well can be isolated using a seal ram around a fired gun because the internal passages through the gun are sealed off by virtue of seals around a hammer piston. The connectors are configured so that an upper gun creates the pressure required to set off the gun below. The connectors are also configured such that when a lower gun is supported by a seal ram, an emergency shear zone is presented opposite a shear ram to ensure that if an emergency well shutdown is required that the shear ram does not have to cut through a section of the gun which contains explosives.

[ What is claimed is:] [1.] A connection to attach a first downhole tool to a second downhole tool, both tools having a longitudinal axis, comprising:a guide on one of said first downhole tool and said second downhole tools to guide movement of said first downhole tool with respect to said second do

[ What is claimed is:] [1.] A connection to attach a first downhole tool to a second downhole tool, both tools having a longitudinal axis, comprising:a guide on one of said first downhole tool and said second downhole tools to guide movement of said first downhole tool with respect to said second downhole tool;a latch mechanism having at least a portion thereof on each of said first and second downhole tools to selectively hold them together;said lug and guide interacting in a load bearing relationship to minimize the effect of longitudinal force on said latch mechanism when said latch mechanism is set resulting from applied load to at least one of said downhole tools.
