Y-T71
Nice looking Series 70 you've got there! How do you like the MMC rear sight? I have one on my Combat Commander and I really like the sight picture I get with it.
Like you, I have heard or read about the fingers breaking off the collet bushing but never experienced it first hand (and I have had a lot of Series 70s over the years) nor I have ever seen or heard of it happening to any others that I know.
Still it could happen (and maybe at a very inappropriate time too) so your playing it safe by going with a solid bushing is definitely a good idea!
