Wrench for the Dan Wesson small frame revolvers. Includes pilot for .357/.38 calibers. .22 caliber Dan Wessons require the optional .22 caliber pilot, sold separately. The great feature of our interchangeable aluminum pilots is you aren't wearing out your barrel everytime you use the wrench...a steel pilot in your barrel bore is not a good thing! The wrench is precision machined out of hardened alloy steel, with a hot blued finish. Take care of your Dan Wesson with a well made tool! Made in the USA!
