The CEO of Ruger, Mike Fifer, response to my question of why they dropped the # 1. Here is his email to me.
Dear Mr. Price,
Your comments are important to us, hence this venue.
If you want a #1 Standard, you might want to check with Lipseys, whom I believe has a variety of calibers in stock.
We dropped the rifle from our catalog offerings because the volume – or lack thereof – dictated that change. We have found, however, that the old adage, "absence makes the heart grow fonder," works for items we remove from the catalog. After they stay out for a few years, it can be worth bringing them back for a limited engagement. All the fence-sitters get one more chance to buy the firearm they were thinking so hard about but never taking action on. So you might see the #1 Standard again.
