4”, fixed sight, half lug, blue .357 GP100 model number?

[awp101]

Paging contender and anyone else that knows the Ruger catalogue better than I (that’s a long and distinguished list BTW). Got a member on another forum trying to find the model number for the old 4”, fixed sight, half lug, blue .357 GP100.

Thanks for any help!

Let me see if I can look it up!

Ruger now uses a model number,, while all us old collectors use the catalog item info. (Such as GPF-340)
The Ruger catalog info for what you seek is GPF-340, which stands for GP (model,) F, (fixed,) 3 (357) 40 (4" half lug)
And yes,, the model number should be 1712.
Look on the Ruger site to see if that's it.

Thanks, I’ll pass along the info!
