Single Trigger Question?

[charlie cleveland]

I have a parker d grade hammerless with a odd ball trigger selector..it is on the left side of the left sideof the opening lever..on the left cheek panel of the stock..it pushes back and forth like the safety to choose the barrel you want to fire...to deep in the tomb to take a picture right now...my barrel selector looks nothing like this one being shown...but I have never seen another one like it...I like this selector being shown...you could choose whitch barrel to shoot in a hurry..you canchange barrels on mine in a blink of the eye..i have 2 lc smith with the hunter one barrel selectors a bird would be out of range real quick using those selectors...charlie
