Hi Kirk, yes, the grips seem small compared to the revolver frame. I removed all the parts from the Pietta Speller & Burr for inspection and degreasing. The internals of the revolver are very clean, nice sharp machining with no burrs or rough areas. The hammer pull on this revolver is heavy. I will replace the hammer spring with a Wolff reduced power spring. The Wolff used in the Colts just needed to be shortened a little. The sides of the hand and bolt will be fine stoned to decrease friction. All the brass has been gone over with Brasso, now drying.
I decided not to shoot this revolver and just use if for display in my living room. To accurately shoot the S&B revolver that shoots very high, a dovetail front sight would be required. That IMO would change the character of the revolver.
Unless something about this revolver changes, this completes my evaluation of the Pietta Spiller & Burr.
Regards,
Richard
