Need a bit of GP100 ID help

I'm doing some research on GP100's and I need to find out some info or where it might be on line.

With the new GP100's that have come out - specifically the .44 spl, the .327, the .22, and the 7 shot model, what do the box end labels say?

example - KGPF-830 tells me that it is a stainless steel GP100 with fixed sights, .38 spl caliber, 3 inch barrel with a half lug.

I can maybe guess how the .44 and .22 will be marked, (KGPF-431 or KGP-250) but not sure about the .327 or the 7 rnd model and with Ruger, you never know and I want to make sure. The 2018 catalog only has the Ruger Catalog Model numbers (1705, 1757, etc.)

I might try calling Ruger on Monday to see what they say or what they may be able to send to me.

Thanks.

Ron, my Lipseys GP-100 327 catalog number is: GP-32751

My GP-100 22 catalog number is: KGP-22-55

Hope this helps.

It does. I have a follow up question for you. Is your .327 a 5" barrel with a full underlug (goes to the end of the barrel)? and what is the length of your .22?

Thanks

Ron, my 327 is the Lipseys special. Blued 5 inch half lug barrel. My .22 has a 5.5 inch barrel.

That helps, the .22 sort of stays with their numbering scheme but the .327 doesn't as it ends with a 1. Being a half lug barrel I would have thought it would have been a "0" (zero) as since they started making them the last number always designated half (0) or full (1) lug.

What i'm doing is making up a chart to show how to interpret the lettering on the end of the box it came in. That was going to go along with a possible GP100 display that I may show at the next ROCS show (at the Ohio Gun Collectors Association meeting in July 2019).

But I still have time to do more research. It might end up that I'll have to limit the chart to the models prior to the .327, .44 , and the .22. I'll see what happens when I call Ruger.

GP100, stainless steel, 327 Fed. Mag. 4 inch full lug, bought new last year.
Catalog # on plastic case is KGP-4327-7, model #01748

44 Spec, 5" Blue, half lug.
Cat No GP-4451. Model 01770

For those of you who have replied, thanks for the help.

A Ruger dealer rep is going to be in contact with me in the next few days so I'll see what he/she can help me with. The girl at CS said they only deal with the model number (1702, 1750, etc.) Even she didn't know what I meant when I said KGP-131. I told her model 01708, she punched that up on the computer she told me it is a stainless GP100, .357 Mag, adjustable sights, 3" barrel (with full underlug).

So the search continues for info and of course I forgot about the 10mm.

I have two data points for your collection:

KGP-4431-5 (01761): 3" stainless .44S, adjustable sights, full lug

KGP-1040-MCA (01755): 4.2: stainless .40/10MM MC, adjustable sights, half lug

I would posit for the recent models, the code is something like (K)GP(F)-(caliber)(barrel length)(underlug)-(capacity), but that's just based on what I see here and have seen, and obviously the MC models don't seem to be marked that way. On the other hand, looking on GB, I see a 4" 7 shot blue .357 as GP-121-7-HC, and several very new models with no model number designation on the box end at all (e.g., https://www.gunbroker.com/item/794556344)

Ruger dealer rep has not called me yet so I'll give them another call today. While I wait, if there are any GP100 owners, let me know what you have.

Thanks

Thanks for the info but I also need the catalog number. It should be on the end of the box and look something like KGP-xxxx
