Issues with Taurus 617 Titanium


September 3, 2012, 08:42 AM
Ok, I just acquired a Taurus 617Ti in .357 mag, made back in 04. It appears it was unfired, new sitting in the box. I took it out and fired a cylinder of 148/7gr fiocchi fmj's out of it to see how it shot. After the string, I was emptying the cylinder and noticed that every round had caused "corrosion" front and side of the cylinder after firing it. It was discolored, kind of like color case hardened and was pitted up badly on the front side of the cylinder, with a little on the sides near the front. Do any of you know if this was a common problem with these models? I notice that the titaniums are discontinued. I have not had a chance to call Taurus about this. I know they have a 100% guarantee on their products, but not sure how they will treat this case. Any input would be great.

Are you sure it's not just powder fouling? Some of my stainless and nickel guns are discolored in the areas you mention but they darn sure aren't corroded. Sounds like its due for a trip back to Miami.

Its called fouling. You are shooting a revolver, its got a gap between the barrel and cylinder. It will turn the front fo the cyl black, and it will even come back onto the sides of the cylinder, perfectly normal. The top of the frame above the cylinder will do it too. When you are done shooting, clean it. The face of the cyl will really never stay 100% clean and shiny, dont worry about that.

Im not a taurus fan by any means, but post a pic before you think about sending it off. It would be silly to send it to them just to find out it was dirty.

Taurus still has the 817T, 38spcl. I bought the 617T new and it was so ammo sensitive I finally got rid of it. It had no problem firing, but the cases would sieze up in the cylinder and I had to drive them out. It wasn't always the same chamber. I eventually did find some ammo that wouldn't lock up, but I don't remember what it was. I actually considered having the chambers bored slightly. Finally just gave up.

It's a nice gun and carries well. It seems surprisingly small for a 7 round cylinder. Of course there's the other problem.......... very painful to light off.

A pic would help. From what's being described by the OP, pitting and such, sounds more than just normal fouling.

Did you investigate the problem any further? I am quite curious what could have done this to a seemingly "new" revolver. Could you please post a close up picture of the area to give us a little more to work with?

There are a couple Taurus fans on the forum that may see your post and chime in with more educated answers for you.

I have own many firearms in my life, to include revolvers. I may not have described it fittingly, bt it is for sure not just fouling. Here are a couple pics.

These are the best I can do on close ups. I think you can see the gouges that are in it. I will be sending it to Taurus tomorrow.

I was using some Fiocchi 147gr. I don't think it was bad ammo, since my friend used some of it on his new Vaquero just 2 weeks ago.

I've never seen anything like that on any of my stainless revolvers. All I've ever gotten was the aforementioned fouling that wipes away, leaving no marks. That does indeed appear to be pitting, though, and looks permanent. Anybody else seen anything like this on a ti gun? I'm interested in hearing what Taurus has to say about that, and hope you keep us posted.
Edit: After a bit of online research, I found a note about taurus titanium cylinders being "coated" somehow to resist "corrosion"(taurus owners manual); that coating can apparently be scrubbed off if someone was to get too happy with cleaning. Also, Ti is apparently more porous than steel, and so burnt powder deposits more easily, and is harder to scrub off...

Looks to me like she's shaving lead BAD. Tight forcing cone or lousy indexing maybe?

It is getting shipped today. We will see what they have to say soon.

If it has a titanium cylinder, you have to be careful not to scratch or rub off any of the protective coating. Once the coating is gone, the titanium will burn and pit when it gets hot (near forcing cone).

Looks like "gas cutting".

September 13, 2012, 03:16 PM
Looks like gas cutting on the top strap, back from the forcing cone. Forcing cone not cut square?

September 13, 2012, 06:45 PM
Looks gnawed - that's the worst gas-cutting I've seen.

They are evaluating it now. Hopefully I will hear back soon. I will leave an update when I get the word. Wonder if they will just send me a new one??:D

This is a common problem with Taurus titanium revolvers. The manufacturer abreviates it Ti. That actually stands for tin, not titanium. :evil:

Seriously though, sorry for your troubles. It does look flame cut pretty bad. I've said it many times. I do not trust Taurus quality.

It almost looks like the bottom of the forcing cone protrudes further than the top, and is causing nearly ALL of the hot gas to blast straight up and into the top strap. Hence the bizzare burns on the outside of the cylinder chambers. I usually see a little fouling there, but nothing like what you have going on.

How is the cylinder lock up? I know you already sent it off, but did you ever look at the cylinder gap?
