Aguila Blanca, boy am I embarrassed! I did not check the link you provided and thought when you put 'this thread', you meant THIS one. I am sorry for my oversight!
Regarding the two position cylinder pin on Uberti revolvers, they have been doing that for a long time. I bought this Uberti Cattleman used, probably close to 20 years ago now. It came with one of those silly two position pins. I replaced it with a standard pin.
I can't tell you how many times I have seen guys show up at the line at a CAS match, only to realize they forgot to pull the pin to the 'fire' position. Click, click, click, after about the 3rd click they realize the dumb pin is in the wrong position. Get rid of that dumb pin, replace it with a standard one, I usually buy mine from Belt Mountain. If you want to dry fire, get some snap caps.
