Best S&W Model 64
I recently purchased two S&W model 64's one is a 64-5 and one a 64-6. Both are fine shooters and the trigger pull is nearly identical. I am not going to keep both and would like some advice on which would be the better choice to hang on to.
Thoughts on what the benefits of each is such as: internal firing pin vs. hammer mounted firing pin and etc... I appreciate any ideas, comments, or links to websites/forums that you might have.
Is one more desirable than the other??
Is there a list of all of the engineering changes for these models with pros and cons?
