I recently purchased a model 22 that came with two barrels. The 4" barrel and shroud goes on and off fine. When I install the 8" shroud it is a very snug fit between the barrel and the pin on the frame. So much so that I am having trouble getting the barrel nut threaded. The 8" shroud has the same tight fit if I put it over the 4" barrel. The barrels are mis matched (1 vent and 1 vent heavy). My guess is just machining tolerances. Any other opinions?
For reference I have owned several Dan Wesson's and this one is definitely tighter than any other that I've owned. Thanks for the help.

First, 
to the forum form PA!
Is the tight barrel buldged anywhere? Have you taken a caliper and measured along its length? Just wondering if somebody had a stuck round and fired a follow up shot with a slug stuck in the barrel, causing a small bulge. If no bulge, compare the measurements of the 'tight' barrel with the other one and see what is going on.
Anything worth doing is worth doing well.

My guess is just machining tolerances. Maybe the hole for the pin is just a little off on the 8" shroud. Is the pin tight in the hole with no barrel at all? Maybe you could clean the pin hole up with a small round file.

OK, I'm not sure I follow. Are you saying the shroud fits tight on the locating pin or are you saying its hard to slide the shroud over the barrel tube? I may have misread your first post. If its just tight on the pin, I think lonwolf93 has the right idea about reaming the pin hole.

I seem to understand that the 8" shroud is a tight fit on the 4" barrel so the problem is the shroud and not the barrel. If the pin or hole is off the shroud should slid freely until it comes to the pin. If not the shroud may be corroded or dirty inside. Maybe sand or file the inside of the shroud if that is the case.

Ole Dog the inside of the shroud is clean and rust free.

As I look at this closer I really do believe that the hole in the shroud is just a little lower than it should be. The pin in the frame seems to be catching just slightly as it goes in. The pin fits the hole in the shroud with plenty of clearance if there is no barrel in the shroud. My real problem is when I go to put the barrel nut on. I can get the nut on about 2 threads and then it locks up. It feels very much like the nut is cross threaded. If I turn the nut any more it locks to the barrel and the barrel itself turns in and out. After I have turned out the barrel and nut combination they are still "frozen" together. If I break them loose slightly the nut goes up and down the threads after that like a dream. The threads look old but not terribly worn. I'll give it another try and see if something jumps out at me.

Interesting. It looks like the barrel nut must have been rubbing the shroud a little on installation. I think the frame pin is pushing the shroud just a little higher than it should be. If i push down very slightly on the muzzle end of the shroud when I install the nut everything goes together as planned. Looks like I need to get to work opening up the pin hole. Thanks again.
