Little tip before you waste a lance...
If you're gonna be buying a standard trigger and lance and you want to put your own bend on the end of the lance, ptfe tape your lance end that is to be screwed in the trigger, screw it in until tight then make the bend in vice. So bend after it's tight to trigger not before you attach as you could be bent upwards when tight.
This won't be a problem if using spigots as they can be turned in the trigger, which comes in handy.
