I've wanted a Uberti walker for a long time. First I made the stupit mistake of buying one from a gunshop here in town, thinking I'll save on shipping, plus I could look it over right there befour buying. I should have went through Dixie Gun Works, or Gabela's, cause they take care of the people, that buy from them. Once you buy from this gun store you can't take it back, for any reason. Got the Walker home, cleaned inside the barrel, cylinder, and nipples. put everything back together people at the shop had already wiped, and cleaned, the outside off and put them in the gun case, they do all of them that way. I put 45grs of pyrodex P, a wad & 454 rd ball in the cylinders just to see how it was going to shoot, and group. Arm over sand bag. Everything went good 4" group at 50 yrds first six shots. I didn't even put corn meal under the ball. Loaded up again same thing, the dang white & orange bulls eye was starting to turn black, cause it was just turning into a big hole Loaded up again fired 2 shots, and the hammer started geting hard to pull back. After the last shot, I took the gun apart right there, they are much easer to take apart, than the smaller colts. I have 2 1860s, 2 1851 colts, and 2 1858s remingtons. Made by Pietta's. All from Cabela's. Never had a problem with any of them. One of my 1858s is over 20 yrds old, over a 1000 rds fired, it's just starting to get broke in good. I put the walker back together, fired 6 more rounds. had to take it apart again, wiped it down again. put it back together. loaded up firded 6 rds did ok, I loaded up again started shooting, hammer was starting to get hard to pull back, this time I could tell the bolt stop was putting a mark just outside the little holes in the cylinder. I stop shooting at this point. 24 shots fired. Took it inside and cleaned it up, hot water and soap. oiled it up, and TC bore butter inside the cylinder & barrel. Put it back together. Everything seemed to be working perfect. I put it up. Got it out the next day, to look it over, pulled the hammer back pulled the trigger to let the hammer down, nothen, hammer stayed put. Hammer spring is the only thing, I know of that would cause this. That was this Friday march 25th, I bought the revolver March 1st. I called the shop, ask who to get in touch with, they gave me 1-800-BerettaUSA, or www.Berettasupport.com Than looked up the Uberti web site, they list Benelli USA ATTN : Service Department 901 Eight Street Pocomoke, MD 21851 Now I'm going to have to pay to send it to one of them. Fellows My question to you is, should I just try to get them to fix it, or send me a new walker. or refund my money, and order one from Dixie Gun Works. They sell for the same price I paid for this one at the gun shop? I would have to pay the shipping. I never had this problem befour. At first it just hit me wrong, if I could have stuck my tung in the in the gun powder it would have went BOOM !
