I second Muley Gil's comment about the smaller frame Convertable, not the same gun as the older frame gun, use some caution in your loading.
I own a 5.5" model but haven't really had the time to work with it much. Love the feel of it tho, seems to shoot pretty good with both cylinders. I need to get this one out and work up a good load for both cylinders.
My only problem with the newer Rugers is the stock, it seems to be rather 'flat' right at the area that your middle finger folds over it, this is pretty painful to me, kind of digs into my finger. I've taken mine and rounded them off and put new finish on them, works much better. Of course a nice set of Grasshorns gilds the lilly.
Enjoy your gun if you decide to purchase.
