You know I own one and don't really know!!!!! But the 1911 in general use's 16 to 18# for the full size. I think that the stock Wolf Spring for them are 18.5# HMMMMMMMM got to check Taurus website and owners manual
The standard recoil spring rating for a 1911 is 16 lb.s. What may also be contributing to the lower felt recoil is a stiffer Main/Hammer Spring, which will slightly delay the slide opening. Check the amount of effort you need to cock the hammers between the Pistols and you will probably notice the difference. My 1911 has a stiff hammer spring/standard recoil spring and seems almost recoil-less at times.
If you were to exchange Recoil Springs between the two 1911's there probably wouldn't be much difference, but exchange MainSpring Housings, if possible, and I bet the Charles Daly 1911 would take on the lower felt recoil characteristic. Also, your Taurus is new and the CD 1911A1 may have more spring wear, depending upon how much use it's had.
BTW, there are some High Dollar 1911's that do come with 18 lb recoil springs, such as Wilson, but I've noticed some of their owners going to 16 lb Recoil Springs. Use of heavier Recoil Springs will depend upon the power level of the Ammunition you use.
