These are Ruger parts that were removed from a trigger assembly for upgrades.    When you order you will get 2 plungers and 2 springs that are in excellent condition like the ones in the pictures.   I do combine shipping, you might have to pay all of the shipping at checkout but I can refund some of that money on my end.  If I have already printed the shipping label and you buy another item, it will have to go in another package and in that case you would not get combined shipping. Thank-you, Bruce.
