10 no dash conver to 2" barrel

[H Richard]

Now you are beginning to see why many of us discourage non-trained gunsmiths from attempting to change barrels. It just doesn't screw off and install a different one. Many things come in to play. I'd give it to a "qualified" gunsmith and let him get it done. In the long run it is worth it.

I finally bit the bullet and fit the 2" barrel because I much prefer it in this configuration. I filed a small amount off of the barrel shoulder with a triangle and small finishing file, checking fit as I went, until the barrel came 1/8th of a turn from lining up.

I then shortened the ejector rod and center pin about 1mm until it fit and re chamfered the inside and outside edge of the tip.

I laid the barrel flat on a piece of 400 grit sand paper on glass and shortened the forcing cone about .004. The forcing cone still looks longer than on my model 10-2.

The cylinder gap is about .003 when the cylinder is pushed forward and about .005 when pushed back so it is good to go.

I wish it took a bit more torque when installing the barrel but the pin should help hold it also. If it ever moved I can just re-install it with a little red loc-tite and and an ovesized pin. Too much torque can cause a tight spot in the forcing cone and degrade accuracy.
