I will be pick up my blued Taurus Model 650 next week. Today the dealer (where I placed my order) told me there were some demensional differences between the CIA 850 (38) and the 650 (357). Specifically he said that the 650 was the same as the Taurus Model 605 while the 850 was the same as the Taurus Model 85. I was under the impression that the 850 and 650 were pretty much identical. The Taurus website does not note any differences. I've owned both the 605 and 85 and although they are built on the same frame there is a noticable difference in size between the two models (2 1/4in barrel versus 2in barrel). Thanks for any info.
