I see. I don't have this problem because I have a quick-coupler<->morini adapter. I have so many airguns with different fittings, I have found the best way is to have a quick-coupler socket on the line to cylinder and quick-coupler plug-to-gun adapter for all of the different guns. I first screw on the adapter and then plug-in the line -no turning of gun necessary. See:

My main criticism of the steyr LP5/50 trigger is the fact that the second stage travel is not adjustable. I like to have it very short rather than "spongy".
