Been thinking about a 7 shot Ruger GP100.
I only owned traditional 6 shot revolvers, are the 7 rounders reliable? Timing issues? The walls between rounds in the cylinder must be thinner, are they still as robust as a 6 shot GP100? |

If it was me, looking for something more than a 6-shooter, I'd probably go with the N-framed Smiths, they're 8-shot .357 revolvers, and the N-frame is Smith's proven, tank-like .44 magnum revolver chassis. Think 629/Dirty Harry.

Decent trigger pull single and double action. I like the fiber optic front sight. It's a very nice shooter. Very pleasant with .38 Special and not bad with full magnum stuff. I don't see why it wouldn't hold up just fine to a steady diet of magnum loads. That said I normally shoot moderate reloads of 158 gr cast/coated bullets to around 900-1000 fps. |

I had a 7 shot GP100, 4.2". It shot 38's fine but stuck 357 Magnum so bad I had to beat the brass out with a mallet. I swore them off and I'll never buy another. Lots of people have had issues with the 7 shot (many not all) and I'm sure Ruger will fix it if you get one and it's less than stellar. I love the GP100 and have a 10mm MC and a 44 Special, but I didn't have a good experience with the 7 shot 357, but all the six shot versions were great.

View Quote mine works fine i typically shoot 357mag handloads thru mine mild to wild with win231, unique, 2400, and H110 never had stickey extraction, until i recently shot a bunch of 38specials thru it afterwards, my favorite 2400 load had sticky extraction i cleaned the (7) chambers really well and it works fine I polished the internals, shimmed the hammer/trigger and put jn a wolf spring kit it’s as smooth as my dash4 686 |

@OP
Run away. Run far away. The 7-shot GP-100 has a documented design flaw. They took the existing 6 shot and just moved the cylinders closer together to hold 7. But there wasn't enough room. Many types of in-spec ammo cannot be inserted in the gun because the rims will bind together. I had one of these 7 shot models and couldnt load more than 5 rounds in it. Sent it to ruger and they swapped me out for a 6 shot match champion model which has been flawless. The 7 shot would have been kick ass if it would have fucking worked. There's a thread over on the ruger forums I was a part of with several other members experiencing the same issue. And some guys on the youtube demonstrating it on their guns. |

Some 357 mag ammo fit in them fine and others did not, even though it was under the max size for the spec. Could be that the cases you're loading happen to be small enough to work. Ruger cannot just fix the issue without completely redesigning the frame, too. The center if the pinning cylinder for the gp-100 is a fixed distance from the bore. That means you only have so much space to squeeze in your 7 rounds. If you try to make the rounds further apart from each other, you end up fighting the laws of physics. The only solution involves designing a new frame thats no longer a GP-100, that has the bore slightly further from the axis the cylinder spins around. |

I have the gp 7 shot a older one that is supposed to have the rim binding issue. I did have the problem with one box of geco 357 ammo. Not the whole box but one time it bound. The rest of the box worked. Tried 10 different 38 special ammo and 357 and it all works,even blazer 38 special. I don't think it's a big issue. On that mentioned Ruger thread another gentleman said he tried 50+ different kinds of ammo and only found 2 or 3 that didn't work.

I load everything up on a DILLON 550b or XL650
I can load them mild to wild usually mixed brass, starline, winchester, federal, etc. never had a problem I rarely shoot 38 brass in my 357’s, but they’ve been fine also . |

Never had a binding issue with multiple brands of .38. However it binds like a motherfucker with various brands of .357, off top of my head PMC is the worst which of course I have a ton of. Aside from the binding it shoots great, trigger is nice and accurate. This thread reminds me I need to call Ruger and get it back to them, hopefully they will just swap it out for a 6shot. |

When I bought mine I knew there was some issues but I also knew it was fairly rare, some guns are worse than others, I also knew Ruger was replacing them when there were issues. |

38 and 357 rims vary a lot from brand to brand. This is why there are multiple thicknesses of moon clips available for 38/357.

View Quote Specs are .428 to .440. if they are over .435 they bind in many gp 100s. Some gps will handle up to . 437. Most ammo makers will have brass around . 433 in fact starline specifically says they keep theirs to . 433. In my gp I was able to load 6 and use the box of Geco that I had. On a side note that stuff was extremely hot. |

I have about 400 rounds through my GP100 7 shot .357. The only ammo that I had problems with was Geco and Precision One. Was not accurate and would not eject. Mine loves Remington 125 grain and 158 grain ammo so that's what it gets. Very accurate and reliable gun/ammo combo.
Overall a very good shooting revolver. Gun is fine, but a tad ammo sensitive. Use quality ammo, no problem. |

I shot the beejabbers out of the new 7-shot GP-100 last Saturday.
This is a Model 1782, 3"barrel w/unfluted cylinder. Very recent production. No binding of any kind. Used Remington, Fiocchi, Blazer brass, and Federal ammo. |

I asked if I could swap it for a 6shot which the CSR said was fine and I should have a blued 6 inch 6 shot on my way shortly. Using the ruger serial number lookup my 7shot was made in 2018 fwiw. |
