P94/GP100
Single-Sixer
My P89 with a 315-98XXX serial number was produced in August 2007, according to Ruger's Custodian of Records. In Patrick Sweeney's "The Gun Digest Book of Ruger Pistols & Revolvers," which has a 2007 copyright, the KP89 provided to him by Ruger also had a serial number in the "315" block. Sweeney states on p. 72 that the P89 was introduced in 1993, and on p. 74 that P89 serials began in the high "304" block. I can't prove it, but I suspect that Ruger ended the P89 production at the point where the "315" block ended and the "316" block began.
As I recollect, early production P89s had both the original-type small shelved safety levers, the lanyard loop, and the barrel breech was level with the plane of the slide. Later P89 production phased in the re-angled/longer-shelved safety levers and the breech to slide angle was modified, the butt of the breech visibly rose above the plane of the slide where the breech fit in to the breech cut in the slide, and the lanyard loop was deleted.
I would recommend getting one of these latter-production P89s, with the key feature to look for being the modified barrel breech angle; I don't know at which serial number block this modification began-perhaps one of the RENE folks, or Coffeepot can chime in with more specifics.
I hope this helps.
Best, Jon
