The 357 was introduced with the M27 in 1934,the 44 was introduced with the M29 in 1955,the 41 was introduced in 1964 with the M58 in the following old ad.
The M58 was eventually followed by the M57. All 4(27,29,58,57) are the large N frame. The 41 Magnum never gained the popularity that S&W was hoping for and then Dirty Harry/44 magnum dropped its' desirability even more. Recently,probably the last 25 years,the 41 magnum has had a tremendous resurgence of desirability. And because of S&Ws' low quality lately,the old ones are at a premium. The M57 pic of my used 41M I put in the above post is of 1980 vintage,I picked it up for $700 this past summer at the Berea show. The seller was complaining that nobody is even looking at it. I couldn't get my money out fast enough. Same ones are selling on the auction sites for double that and UNIB are in the $3000 range.
Just as the 41 Magnum is coming back,so is the 10mm.
Back in October at the Berea show,I picked up aftermarket N-frame wood grips for $20. After that transaction I was looking at the guns under glass in his case and asked him 'what is that' as it barrel cartridge ID was facing down. It looked like a S&W SS full lug 6 1/2" unfluted cylinder 44 Mag. He turned it over and it was my 'holy grail' 10mm revolver. It was the first one I ever seen in person. He had a tag of $2100 on it. I didn't want to put it in hand,I was just glad to see it. This was on Saturday. I went back on Sunday for other stuff and talked to him again. He said someone offered him $1500 and he told the 'offerer' he'd have to do better than that. This past Saturday at the Medina show he said he was gonna accept the $1500 offer and that person was supposed to show up at the Medina show sometime. I went back on Sunday with Andy(he's one of the youngsters in town for auto mechanics school working at Tuffy with me). He's interested in guns but he's from the restrictive state of New York and never been to a Ohio gun show. I was there with $600 looking for a project gun to convert from 40S&W to 10mm. He still had the 10mm revolver and I told him if I knew that $1500 was acceptable,I would have pulled the $1500 out Friday. He said put a $100 down and pay the rest at this weekends upcoming Berea show. I did and I'll have my grail gun. I'll post a pic when I get it.
