the only thing the pre 29s early 29s and i believe the first 57s had over a 27 was the "coke" target grips. the later S&W targets are just so fat mid toward the butt end. If S&W would have seen it to install the Coke targets on the pre 27s, earlier 27s, that would have been the cream on the pie. I think the Magna grips feel and also look good. Dryheat`s photo up a ways in thread shows Magna CP grips, sweet! and of course the pre war Magna stocks are tops.
