Ya that’s what I think this guy is. Don’t want to outright bash him. Didn’t keep me updated as he should have. I saw there are chamfer reaming kits I could try. And have new cylinder pieces to see if that fixes the timing issue.
If you have the parts & ability and skill to fix the timing, then you should do it. There are books by Jerry Kuhnhausen that can tell you just how it's done. As far as the forcing cone is concerned, WHY does it need cutting? Didn't it leave the S&W factory already with the cut? I have yet to see one that didn't. While some GS's like an 11º cut, it is not essential and the factory doesn't do that.
I have cut a few of my FC's to 11º and to be honest I see no difference in accuracy, leading, etc. Yea, maybe in theory but in my experience it makes so little difference to a properly aligned barrel, I would not bother.
These days it is just too much of a hassle and far too expensive for gun-smithing out of town. Forget about the wait times at least for competent GS's. I would avoid it at all costs and would urge anyone with the ability, skill and a few tools to learn these skills themselves. Going forward our society as it stands right now wants to make it as expensive, as much of a hassle and as illegal as possible to ship firearms. We will soon be at the point that you would be better off throwing away or selling an old gun, then just buy a new one rather than to ship it out. This is their plan. Then new guns will either be so restricted or illegal to buy. Not an accident!
At this time
new guns are repaired and taken care of by the manufacturer, including sending a call tag and paying for the shipping. Let's see how long that lasts! I have always advocated for anyone that has the desire, tools, skill or desire to learn how to maintain and repair almost anything mechanical themselves. We are rapidly returning to self sufficiency, a practically non repairable item, or pay through the nose scenario.
