Different Size Safety transfer bars?

I have been dry firing my Ruger Bisley 45 Mew Model quite a lot and the transfer bar broke, called Ruger and they sent me one for no charge, really good service by the way.

Well, I went to install it today and the top of the bar doesn't come to even the bottom of the firing pin, so I called the nice folks at Ruger and they're going to send out another one to me.

Is there there more than one size of transfer bar, if so, would the shorter bars be used in say a Single Six?

I just always figured there was only one size for the New Models.

Thanks hunter966

There can't only be one size. The larger the frame, the higher the firing pin is.

Yes, they likely sent you a Single Six transfer bar.
