I have ordered Taran's base pads, springs, followers. They get out orders in a few days, but the post office where they are is pretty poor and loses stuff right and left. However when they do TT stands up big time. The post office there lost my order, and TT called me back that afternoon because the tracking number was issued but never moved. TT because of the hassle sent me a couple extra packages of mag springs and followers for the hassle.
One problem with the shotguns, pistols is the time custom building them, plus if one of the gunsmiths get sick, goes on vacation stuff gets behind. Now they should let you know and give you some idea on delivery.
