Have a couple questions?

[jumpsteady]

     Ok, I have a couple of questions. I have a 10" .357 mag barrel that is hard to open once it is closed onto the frame. I have an older 5 digit frame, # 827XX. I believe that there is something wrong with the locking lugs (locking bolts), whatever they are called. The barrel works fine on my dads frame, which is where I got the barrel from. Any ideas of what I should do and or look for? The barrel does have the two piece lugs bolts whatever.
     Next, where can I get a couple of the threaded dovetails that goes into the barrel? I am going to cut my barrel for a second dovetail just like the super 14" barrels. I could just make one but for one I don't have the time and second I'm sure that I can't make one as cheap as I can buy one for.
     Thanks for the help.  Jumpsteady

For the barrel top hats is what most call them you can get from tc, second some barrels have to be fitted to frame I had the same trouble with a new barrel. the barrel is locking up too tight and will not release,
You can take a small sharpining stone and hold it as the same angle as the locking lug and hone a little off the lug and check if still hard do it again till it opens good. you can also use a dremil tool with a sanding disk but that tends to take off too much too quick best to use stone hit it a few times and check till it open ok. the one I had only had to hit it 3 or 4 times and worked fine.

Are you honing the egde that is paralell to the barrel face or the chamfered edge along the bottom?
