I have one that I traded away an excellent Taurus 990 22LR for (the LAST time I will EVER get rid of a gun I like!!) Man, did I enjoy that 22. Even my 62 year old mother enjoyed, a great deal, shooting 12 ga hulls at 7 yards with it.
The 85UL I traded for; I disassembled it right when I got it, to clean out the action as I always do with a new to me firearm, especially on this one because I felt the cylinder release was way too difficult to operate. Immediately I knew something was up as the firing pin retaining pin simply fell right out. As it turned out, the firing pin is totally unremoveable from the frame. Maybe the guy traded it away after firing loads that were too stout?
Well, I totally buggered it up after that. Upon reassembly I couldn't get the "hand" (?) to grab the cylinder as it rotated. Disassembling again to double check my work, I lost the sear spring and the sear spring pin (poor attention to detail and didn't use a plastic bag as I might usually do, in my unacceptable haste). I believe my past maintenance on revolvers was pure luck given everything I got wrong on this one.
It has been over 2 years that I have owned it and I still have the revolver totally disassembled in pieces in baggies, never having shot it a single time, because I just can't justify spending 80 dollars on shipping to Taurus to troubleshoot the possibly mushroomed firing pin, replace the parts I lost (they are never available on Numrich), etc. I am sure the shipping and the bill they will give me will far outweigh the cost of just buying a new one. In the back of my mind, sometimes I wish for a gun buyback to come to a nearby police department so I can simply take my fifty dollars and buy ammo for something else.
