Sorry but we do not have any way of telling when your pistol was manufactured. According to The Blue Book of Gun Values, Phoenix Arms's current manufacturer has been located in Ontario, CA since 1992.
FURTHERING THE LEGACY, ONE PART AT A TIME
After your reply and a consistant "no answer" at Phoenix Arms phone, I went old school and wrote them a letter. Much to my surprise I received a phone call the day the letter arrived (much earlier than I had expected) at their offices. They informed me that the gun was manufactured in 1998--so I was WAY off on my recollection of purchase date--and that I had registered the gun for warranty purposes and that's all they could legally tell me. I was very satisfied because it was the warranty I wanted to nail down.
Thanks for you help!
My hat's off to the good folks at Phoenix Arms for such a personal and prompt reply!
