GP100 - 6 or 4.2?

This is a discussion on GP100 - 6 or 4.2? within the Ruger Double Action forums, part of the Pistol & Revolver Forum category; I have both. Recoil is really about the same. Sent from my iPhone using Tapatalk...

Thanks everyone for your responses and advice. I decided to go with the 4.2 inch barrel. This will go nicely with my 357 LCR snubbie!

I got a good deal on a NIB one from a seller on Gunbroker. The seller has a A+ rating, so I'm fairly confident. I purchased my Ruger 9e on Gunbroker and am very satisfied with that purchase.

Now just waiting for my friend to send his FFL license to them so they can ship it to him.

Iowegan, those are two fine looking firearms!

Pam, I think you're going to be vary happy with your choice.
I've always considered a 6" barreled revolver to be a dedicated target gun or a hunting gun. The 4" revolver is by far a more "all- around" gun, IMO.

A 4" barreled revolver (4.2" by Ruger to make our Canadian friends happy) is a very good compromise. A 4" barrel provides decent sight radius without being as unwieldy as a 6" revolver. If you have ANY desire to carry the gun the 4" barrel is the way to go.

The extra 2" of steel on a 6" barrel adds weight and bulk. The benefits are slightly higher velocities and slightly longer sight radius, neither of which are worth the weight/bulk penalty, in my opinion.

I've been playing with revolvers for a long time and the 4", 38/357 DA revolver is about the most useful firearms tool you will ever find. It does a LOT of things really well.

Enjoy your new gun !

Pam when you get your new Ruger GP100 be sure to post some pictures when you can. I am sure you will enjoy it. I still am a S&W fan but like I said earlier now my GP100 is my favorite. The design and weight of these fine guns really help with the recoil and they can be very accurate as well. Good luck to you!!!

Congratulations on your new (to you) GP100.

I was going to cast my vote for the 4.2" as I have that same combination (LCR .357 and 4.2" GP100).

Now you just need a .357 mag lever rifle and you will be all set!

I've had a first-year (1986) blued, 4" GP100 for about 26 years, now. It is pretty much my favorite handgun. If I were to get another GP, the 3" version is the one that strikes my fancy, first. But the other one I really like is the partial underlug, blued 6" version...

So, I'm obsessed and bored.

I dug up the actual weights of the two firearms from the Ruger site. I went to the BBTI site and got velocities for each of the barrel lengths for a 158 grain Federal JHP. I then assumed a 15.5 grain powder charge and here are the results.

:::drum roll, please!:::

4.2" barreled model: 40 oz. 158 grain @ 1309 w/ 15.5 grains of powder = 10.26 ft.lbf
6.0" barreled model: 45 oz. 158 grain @ 1465 w/ 15.5 grains of powder = 10.77 ft.lbf

In my humble opinion, the difference is insignificant.

The velocity difference depends on the type of powder as well as the charge. But consider as you add more to the cartridge and fire it through both barrel lengths, you'd see a more pronounced gain with the longer barrel. So for instance, the lighter bullet 110-140 grain defense loads with more powder are screaming out of the 6" barrel at 1600-1700+ fps, where the extra powder capacity is wasted in the 4" and there isn't much gain over a lesser charge.
Heavier bullets with a lesser charge tend to show less dramatic differences, as the 4" is more efficient with less powder, in general.
But again, it depends on the burn rate of the powder. The 6" is more versatile therefore, if you hand-load.

Congrats Pam on your new purchase!! I have the 6" model and am contemplating a 4.2" just because. I didn't see this in search mode, but at Cabelas the other day I saw a 4.2" with the rubber/wood insert grips and green F/O front sight. Im posting a link, but you have to choose #2 of the 4 pictures and scroll down for the info. Its listed as model # 1762. Doesn't show on Rugers page as even being offered. Anybody know more about this? Thanks Ron

Sounds like the new .44 special GP100 that you were looking at. It may just not be on Rugers website yet. Was just announced at shot17.

Description (on Cabella) states the 1762 is a 357 magnum though.
