Cracked Slide?

As I was putting away the Witness last night, I noticed a crack in the 10mm slide. Here are some photos.

Photo #1: From above
Photo #2: Edge-on


Photo #3: the interior crack is barely visible here, although it is quite easy to see in the metal itself. That prominent line perpendicular to the ejection port is a casting mark.


To my eye, the crack appears to go right through from the exterior of the slide to the interior. The external crack is highly visible in these photos, but the internal crack was very hard to photograph.

What say ye? I bought this gun new in April '08. It has about 500 rds of ammo thru it, mostly Double Tap. Is it still under warranty?

I doubt if it is still under warranty, but the cost of a new slide should not be prohibitive.

However you can always ask. Since the 10mm Auto roung IS a high intensity round, others may have had the same problem.

All The Best,

Less than a year old I would sure hope they'd fix it for you!

Less than a year old? I would definitely send it back for replacement. If they give you any grief write a real nice post on their lack of customer service. That might get their attention!

It can't hurt to try. You might also check someone like Numrich to see if they have slides.

I think that gun needed a heavier mainspring for a diet of hot 10mm.

EAA was pretty god when my ex sent one in with a -- cracked slide! This crack was under the ejection port, an area where a lot of guns are stop-drilled or have a slot cut to forestall cracking). That gun was a private purchase, so it had to go back to the original owner and from him to EAA, etc. Complicated but it worked out okay, all covered by the warranty.

Hi Turk,

If you'd like some (aerospace-quality) insight into how far that crack goes, drop me a line. This sort of thing is right up my alley.

I called EAA last month about a 10mm upper for my Witness...229 plus s&h. May save you some headaches.

What's the poundage on the factory recoil spring? Anyone hazard a guess as to what it could/should be raised to to prevent slide battering without causing functioning problems?

And, is this sort of cracking a result of slide battering, or something else?

Turk Turon said...

I've read, over on the 10mm forum, that the stock recoil spring is 14 lbs. What does that mean? Fourteen pounds per inch? Anyway, I tried a Wolff 22-lb spring a couple of months ago at Pop Guns; it was too strong. It would'nt cycle; even with Double Tap ammo. So I put the original spring back in. Probably the 18-lb spring would be about right. Meanwhile I have written a letter to EAA about this; we'll see what they say. Even if they won't replace it, I'll buy a new slide and barrel, but there are vendors who sell these things for $190-200. I might just get a 45-ACP upper set, too. I recently fell victim to a severe case of Kimber Lust and added a new caliber to my inventory. Couldn't help it! Not my fault!

Tam said...

Yup, a 14-lb spring sounds light.

A lot of people overlook the mainspring's role in controlling unlocking and the initial rearward movement of the slide as well...

As someone with a 10mm Witness that eats a fair amount of Double Tap, I'm not happy to read this. Will be examining things carefully, soon.

I found a similar tale of woe on the 10mm forum, along with a nearly identical photo. What a coincidence!

Update? Did EAA replace this for you. They have a "lifetime" warranty and all...

Turk Turon said...

Yes, EAA replaced the slide without charge. The UPS shipping charges are astonishing!
