OneBulletDan,
The S&W DA trigger pull was better than the Colt's. In 1963 I was looking for a fighting handgun and that meant DA. I think the Python SA pull is great, as is the SA pull on my S&W. Back in '63 I think the Combat Magnum, aka M19, was the best choice. Perhaps the overall best .357 at the time was the S&W 357 Magnum, what we now call the M27. The Python was then a very nice choice as well. But the Combat Magnum was the lightest of the three. Costs were not much of a consideration at the time. A Python MSRP was $125, the M27 was $120, and the M19 was $110. The one I chose was to be my graduation/commissioning present. But, lucky me, I had the opportunity to shoot all three of the revolvers we are talking about and some really nice Colt and S&W target revolvers as well before I made my choice.
I liked the Army issued M1911A1 at the time and used an AMU worked over one for competition and twice carried an issue M1911A1 on patrol in Vietnam where I was in an infantry role. But, I liked the .357 better for everyday wear -- I thought the .357 would reach out more and would be more reliable. If I knew I was going to get into a big fire fight, I usually left the pistols at home and just carried my M2 carbine with even more extra ammo for it. In the end I guess I let the M2 carbine do the talking and never did shoot a pistol or revolver at anyone, thank goodness.
