New GP-100

[Charlie Two Tracks]

I went and bought a new GP-100, 6 inch barrel in stainless steel today[smilie=w:. Too bad I live in Illinois and will have to wait until at least Monday afternoon to actually take it home. I plan on keeping that jacketed stuff way away for this revolver. I do have some jacketed ammo around but I keep that stuff for way down the road. I would assume there is no special break in of the revolver using cast but that is why I am posting. I've assumed before and ......... well, you know.

[lwknight]

I hope you got as good a barrel as I did on my GP-100.
It shoots like a laser and does not lead up.
I shot a couple hundred rounds of jacketed magnum loads and 1000s of cast through it.
Still showing no wear. I did work on the trigger several times and its still not a Smith but , its not bad either.

[Harry O]

I got a good one, too. That has not always been the case with Ruger. However, the GP100 I have shoots Lyman 358156-GC with full power loads accurately and without leading. Good luck with yours.

[Old Goat Keeper]

Got me a GP-100 in .327 Federal Magnum and love it for carry! I have only shot factory in it so far trying to get a stock of empty brass.

Charlie what caliber is your GP-100?

[HighHook]

That gp100 is a great cast shoot'in mother scratcher!!!

[Charlie Two Tracks]

Old Goat Keeper. It is a .357 I have an SP-110 (3") in .357 also. Great little snubby.

[geargnasher]

A buddy of mine has one, 4" SS in .357, but it wasn't one of the good ones. Firelapped the thread choke, roll-lettering restriction, and front sight restrictions out of the barrel, and opened the .355 cylinder throats to .358, got some decent sights for it, and finally got it to shoot. Really sweet gun now, built like a 250lb anvil and shoots great.

It is built like a tank for sure. I like mine pretty well. Shoots well enough to suit me and it will never wear out. Mine needs a bit of fire lapping to remove constructions. Likes to lead at end of frame. Larded about leading when I bought some 158 commercial RN. Turns out they were sized to .356. After 50 rounds I started to get some keyholes at 25 yards. Not a gun issue, a bullet issue.

Never have measure the throats. Probably ought to give them a look with Rugers love of undesized or over sized throats.

[Jailer]

I've had a hankerin for a stainless 4 inch GP-100 for a bit now. It's on my short list.

[*Paladin*]

I really like the GP, but lately I've been watching the local shops for a Security Six in SS. A little lighter for packing in the hills than a fully-underlugged GP...

[GP100man]

Congratulations on your purchase of the most robust production 357 magnum revolver built !!!

It`s built to shoot every day , all day , with full house loads !!!

Check the cyl gap & endshake , write it down than check it at 500, then 1,000 rnds & compare it to new , it`ll open up a bit at first then it`ll settle in & be fine !!

I offer this tool for making removal of the trigger asm . easier& safer , just send Ken $10.00 tell em what it1s for & get em to PM me , & get me shippin info .

I got my gp-100 before they quit making the half underlug. Well.. I guess they quit making it. Everything I see is full underlug now.

[dualsport]

Ed Harris has called the GP100 "the poor man's Python". I sure do miss my Security Six, should have kept that one.

[Charlie Two Tracks]

I have the IBOK's for the SP-101 and GP-100. I know that on the SP-101 it made a world of difference. Sometimes Ruger will send out a less than perfect revolver but they will make it right if there is something wrong. I had to send my 101 back and they replaced the cylinder, crane assembly and barrel. (I know, that's most of the revolver) anyway, it came back great and I am well pleased with it. The fit and finish on some of the Rugers are less than perfect but with a little work, they turn out to be a very reliable revolver. IMO

[WHITETAIL]

I bought my wife a SP-101 in a 3 inch
she packs it every time she goes to our cabin.:cbpour:

[fecmech]

I have a blue 6" with no lug that I bought in 1989. I put the Wolf spring kit in it along with a trigger stop and the single action trigger is as good as my K38 (2 lbs.). The double action is close but "stacks" just before breaking but still darn good. Cast magnum loads will average 2"@50 yds while .38's a little worse running 2.5-3" at that distance. Overall an excellent gun for the money. To date it's had about 8K through it about 80% of that magnums with no problems. I had to mess it up with a dot sight cause my 67 yr old eyes don't do well with irons anymore. I think you will be very happy with your new toy.

[MtGun44]

Putting a few hundred jacketed down the barrel will smooth it if you keep the copper
scrubbed out every 20-30 rds. Can make the bore more lead friendly in the long
run.

Jacketed won't do squat for major restrictions or undersized cylinder throats. Ruger makes their cylinders and barrels out of Kryptonite or something, REALLY tough metal.

I am surte you will like your GP 100. I have two of them one I bought from a friend who got it years ago it has no lug, fixed sights and is in 38 spl. It is a fine gun to carry when I am camping for plinking etc as its stainless. I also own a blued security six 4 inch and a stainless six inch. My secoond GP 100 was an unplaned event. It is SS and was in the case of my local dealer so on a wim I asked to see it. It is one of the new ones with the hoge grips. My hand fell in love with the grips as they fit me perfectly and then I tried the trigger expecting the usual ruger trigger. Boy was I surprised! The DA trigger felt just like the custom Colt Python I have that went through the custom shop. Ruger must have made a mistake on this gun as the DA measures a very smooth 5 pound and the SA a crisp 2.5 pounds. Withouy further though I bought it and it shoots as good as it looks. I guess I just got lucky. I had to do trigger jobs on all my other rugers to get the trigger acceptable but this last GP100 beats them all for good trigger and shoots better than the rest as well. I wish you luck with yours. By the way my 4 inch blued Security Six dates from the early 70s and has at least 50,000 rounds through it and it is still tight and as accurate as it ever was. If I was you I would not worry about wearing your pistol out.

[Down South]

I also have a 6" barreled GP-100 in stainless. It's one of the newer GP's with the full underlug. I did an IBOK trigger job on it and replaced the sights. I reamed the cylinder throats out to .358". It's a good shooter.

[Calamity Jake]

I have 2 full lug 6" SS GPs and 4" SS sec 6, does that say anything?

[dualsport]

I had a 6" blue Security Six in the 80's that I had a gunsmith do the trigger. It was a sweet gun but I had to sell it to feed the horses or something. Since then I've thought about a GP-100 but am a cranky old fart and resistant to change. Some of you know your guns better than I do, what does the GP have in common with the old Security Six and how do they compare? Used Security Six's are common, I could get another one, but maybe it's time to catch up with the times?

[theperfessor]

I used to have a Security Six. I now own a GP-100. Compared to the S&W product line, I think the S6 was more of a K frame size, and the GP-100 is more the size of an L frame. Both are fine guns, wish I still had the S6.

[Charlie Two Tracks]

Just picked up the GP-100 last night after work. I can detect no problems with the fit and finish. The BC gap is .006 with very little endshake. It may be awhile until I can fire it. The closest range is 25 miles away and snow can change my work schedule. I do have time to get it shined up and smoothed out. The trigger is better than I expected. The test casing shows the firing pin hitting dead center. I am pleased so far.

[robertbank]

I love my GP-100. The throats on mine are far to tight for lead boolits and I will open them up this week to .358. Plis one on Gp100Man's tool. Works slick and makes disassemble soooo much easier.

I also plan to shim my hammer as it drags on one side. Rugers are great guns I just wish they would finish off the details a tad better.

I also installed a Hi-Viz front sight and am very pleased with sight picture. I plan on using the gun for IDPA ESR division using 158 gr RN boolits.

O man o man
I had one of those,a GP-100 Stainless Steel 6 inch full lug barrel in .357,used at our pistol club,until the local state government decided we could not keep them,unless we did a minimum number of shoot and it was hard considering our pistol club was over 150kms away,so I had to hand them in.
But a great gun,had my trigger lightened and the replacement springs,very accurate,ohhh to be able to have them again.

[Charlie Two Tracks]

Here is what I did to check out the throats and barrel- I took a pure lead 158 gr. FN boolit and drove it through the barrel more than once. Each time it slid a little easier and after the third time, I could push it through by hand. I could feel that the muzzle was the tightest and there was no restriction at the forcing cone. Then I dropped the sized boolit through each chamber of the cylinder and they fell through with room to spare. I then took a .357 jacketed bullet and had to push it through each chamber of the cylinder with a unsharpened pencil. There was resistance but not great. As far as I can figure, that means that it should shoot cast ok. The throats are bigger than the barrel. Right?

[robertbank]

Yes you are right. I wish I could say the same thing about my GP-100.

I just got back from the range with my GP-100. It worked great! Groups are really tight and when they weren't, it was my falult. There was minimal leading in the first inch of the barrel but it came right out. I tried four different combinations of rounds. 148 TLWC W/ 3 gr. BE in a .38 case, Mihec 158 HP W/ 6.2 gr of Unique , 158 RNFP W/ 6.2 of Unique, and a 158 SWC (store bought) W/ 7 gr. of Unique at 16 BHN. I had this last one left over from when I didn't cast my own. This revolver is going to make me look better than I am. Now to get my H-110 out.

[theperfessor]

Isn't it great when things come together? I'm like you, my GP-100 is better than I am - sigh.

[robertbank]

Well my cylinder throats are all nicely reamed out to .358. I am off to the range later today or tomorow to test her out.

I have the KGP-161 full underlug 6". I replaced the trigger spring with Wolf light springs. Got a weaver 2-8x scope on it. My gun shoots less than 2" at 25 yds using Lee cast bullet 158 TL RN using Hodgdon Universal. Great gun and built to outlast me.

[HighHook]

My buddy was hitting a 200yrd gong 6 out of 6 weaver stance with his gp100 6in and i had to buy one a few years ago. 5k cast boolits later it just keeps shooting better and better with age and mileage. It is my favorite revolver.
