I'm thinking about getting into some of the Sierra style pens since there are a few pre-drilled blanks out there made only for the Sierra. My question is...does anyone know if the Majestic Squire found on the PSI site is the same basic pen as the Sierra when blank and tube are concerned? I would like to use the Majestic Squire kit, but use a blank made for the Squire...will this work?
