Muzzle Crown GP100

First of all, hello to everyone on this site, as I am new here! And I might add, VERY glad I discovered this site! Enjoy it a lot!

I've been on the "other" site for some time, and like it too, but find myself spending an inordinate amount of time here lately, mostly browsing the forum and basking in the wisdom so evident in many postings!

I recently purchased a Stainless 4" GP100 and absolutely love the gun, fit, feel, and function, etc. The one thing that dismays me is that after I got it home I noticed the muzzle end of the barrel was not as buffed or polished as the rest of the gun, then, to my horror, as I checked everything real good prior to my purchase, I noticed the crown seems a bit "rough" and slightly uneven. When I first inspected it, it appeared fine. But throwing more light and some reading glasses to it, it seems the taper is fine, but not even around the circumference of the crowning job, if that describes it good enough.

Well, I have always loved revolvers, and shot them well. I took this one out for the first time last weekend and although the groups seemed "okay" at 10 yards (initial sight in), they opened up to what I consider unacceptable at 25 yards...which I figure is my functional max with a 4 inch gun.

The only other time I ever had crowning and subsequenty accuracy issues with a gun was with a favorite Marlin, which after a nice, careful "home recrowning job" went from horrible accuracy hitting the target perhaps once in every 5 shots to (after the crowning job) hitting 1" groups effortlessly at 50 yards !!!!

I DO NOT want to attempt a home crown job on this Ruger if either Ruger can do something to make it right or I hook up with a competent gunsmith.

Anyone else have poor crowning issues with their GP? I love the feel and heft of the gun, and was considering either calling Ruger or talking to a gunsmith...then thought of all you other Ruger nuts on here (among who I count myself most rabid) and thought I'd ask you all first!

Any thoughts?

I would be very surprised if there was an issue here, but obviously you do, and you have the gun.

I would see if I could get a gunsmith to opine on whether there is an issue with the barrel as you describe. If he says there is, the gun should go back to Ruger. Their customer service is legendary. Or you could take photos and email to Ruger as others on this forum have sometimes done to good effect.

Let us know what happens.

This is the first I have heard regarding this issue, I agree with Redleg on the solution. Some pictures would be nice and I am curious- is this a new gun? If so, then back to Ruger asap, if not, I wonder if the gun fell victim to some table-top customizer with a hacksaw and a countersink bit.

I bought it new on March 11, 2011.

Admittedly, I may be "overevaluating" my gun, but having been involved in shooting recreationally for years and having owned many guns, it just seems something ain't quite right.

The finish around the muzzle and the crown itself seem a little rough, and we all know that "a little rough" around the crown could spell trouble, possibly.

Don't get me wrong: I absolutely love this gun! I will try to get pics up in the next day or so. I may try to measure the "crowning cut" at different points of the circumference from lands to outer edge of crown taper as well.

This just seems to me to be an area Ruger would have not sluffed on quality control, but there is always a chance it slipped by. I just noticed the other day while re-examining the gun that the top of the barrell just to the front of the front sight is also full of machining marks and didn't get hit by the final buffing either. The trigger group I have been unable to get out and do not want to force it either. Tried a screwdriver and safe yet significant force...but short of putting the grip frame snugly in a vice and tapping with a hammer, I just don't want to force it.

So a few issues but overall the gun functions great, but the expected accuracy seems off to me. With my Taurus .44 Magnum I could shoot tighter groups than with this gun, which surprises the heck out of me since the trigger on this GP is awesome in single action and smooth in double!

So I have basis, I believe, for my crown concerns on the GP.

Later,,,at work and have a meeting to get to!

Again, thanks for the feedback and answers so far.

Anyone else ever get a Ruger with an unfinished, "rough-looking" crown?

-Jeff



Thanks for the responses so far!

PM GP100 Man for a Ruger Popper. Makes removing trigger group much easier, even on very tight trigger group/frame fits.

I have looked at my GP-100's crown before and thought about the same thing. Mine looks a lot like the top of an aluminum baseball bat with a hole in the center and the hole for the sight. It just looks rough. Brownells sells all sorts of crowning tools but I don't think I'm going to get that much from doing work like that on this gun. On a nice rifle yes, on a four or even six inch revolver no, on a longer barrel revolver that would be a definite maybe...

Well, FAX'd a letter to Ruger today describing my problems with the GP-100, and I received a call within a few hours from a gentleman named Gil in Customer Service. He said he could have UPS show up with a shipping label Wednesday, April 20th, and they would make sure I am taken care of! Cool! I never expected this to take place so fast and in such a friendly manner! Very impressed so far!!!!!

Well, the GP is currently in the hands of Ruger. So we'll se where this goes from here. The crown was definitely lopsided, deepest cut at 11 o'clock position and shallowest at 5 to 7 o'clock position (lands and grooves)...and rough!

Send it by UPS (Ruger provided label) last Wednesday. Tracking indicated it was signed for at Ruger today at 11:14 AM.

Mentioned the trigger group to them as well...so we shall see.

I will say Customer Service has been exceptional when I spoke with them by phone...very customer-friendly and professional. In this day and age...that is SO VERY refreshing and welcome!

Take Care,

Well, UPS should be delivering my baby tonight. I will post an update either later this evening, or as soon as I get a chance to wring it out at the range.

Sure did miss my stainless beauty!

They made an attempt to deliver at 3:41 PM before I got home from work...after assuring me it would be after 5:30!

Heck, at home right now awaiting UPS!

Happy Friday the 13th!!!! lol

Very, very impressed!

Just received my GP100 back from Ruger a couple hours ago and all I can say is a resounding "WOW!!!!"

I have always loved Ruger products, but their Customer Service Department has just solidified my already staunch resolution as one among many Ruger loyalists!!!!

I have to admit that for a couple seconds when I saw that UPS truck pull up I felt like Charles Bronson waiting for his friend "Wildey" to arrive (Death Wish 3)...well, yeah, only momentarily in that fun little Carnival between my ears...but heck...being without one's GP for a spell gets one a bit giddy when it finally comes home!

I CAN SUM IT UP LIKE THIS: GREAT JOB RUGER!!!!

They made the necessary repairs to the trigger group, trigger release plunger etc., and I swear it smoothed up some in function (although it seemed very smooth from the beginning), but heck!

They opted to swap out barrels. The muzzle crown on the replacement barrel (after my scrutiny and near OCD-like examination) is flawless. A stark contrast to the other muzzle crown!

They performed their routine checks and shot a group at 15 yards and included a photocopy of the target. Of course I will be wringing it out myself in the near future, but dang! Impressed!!

As an aside, at the bottom of my typed list that I initially sent in with the gun I hand wrote a note that if they ended up having to switch out barrels to remedy the problem, it "wouldn't hurt my feelings at all if they put a 6 incher on rather than a replacement 4 inch barrel" since I would primarily be using it as a backup gun for deer hunting.... Suffice it to say that to my elation they took my hint quite literally (I honestly didn't expect them to, but quietly hoped they would and would have been content had they not).

So now it is a 6 inch GP!!!! I love it!

Coming back out of the clouds after staring at the lusty piece of brushed stainless all afternoon, and somewhat more down to earth, I look forward to testing it at the range myself and will report on it in the near future.

This customer is "more than satisfied" so far! They have definitely exceeded my expectations!
