Hola, Roberto! Que fue? I have the 2.125" Model 60 you are asking about, in the LadySmith variant. It is a wonderful little gun that handles .357 ammo well.
I prefer the 110gr JHP magnum loads as I can control the gun better. I did, however, change out the wooden OEM grips for a set of Uncle Mike's boot grips.
I also own the Ruger SP101. It is a fine gun that I have never "taken to." It sits in the safe, forlorn and unloved.

But that's just me, not the gun.
I prefer the double action of the Model 60. And the 60 is used evenings as a bedside gun.
Both guns ARE .357s. They are designed to be used with .357 ammo exclusively, if you so choose. I do. Hope this helps. Te veo.

Yes, I have maked up my mind, the S&W Model 60 2.125" barrel in .357Magnum, using 158gr ammo is what I need!!!!,I can stand the recoil of 158gr and muzzle blast of this "little beast"!!!!... Remember here in my Country we are only allowed to use only FMJ or JSP .357 mag ammo for defensive purposes!!,as you say it has a
better double action, shorter hammer travel also, which means more speed and accuracy, than the Ruger.
My very most doubt...., was if it could stand ( if it will "last in time" in mechanical order, no issues) the use of .357 magnum at a rate of 25 rounds monthly with other 25 rounds of standard .38 Special ammo during six month a year ( one month shooting the next month not, and so on.....), if it does´nt qualify to do this i think there is no use in buying a Model 60 in .357magnum caliber, and I would choose the Classic Series Model 36 +P rated!!!



Thank you for your information!!
