ECO Recoil Spring Assembly Frame Damage (Break-In)

New DW ECO 9mm has about 300ish rounds fired and i am wondering if this is normal break in or an issue. The recoil spring assembly is cutting into the frame at the point that it makes contact on the left side. Its formed a nice burr behind damaged area. The right side is ok just a very small notch formed. After i discovered it i rented a number of 1911's Kimber, Ruger, Springfield all with aluminum frames and not a single one had this type of issue. In fact the internal area on these guns was almost free of wear but my ECO has all kinds of wear. Is this a product of the tight fit and the slide/barrel/spring find there own fit in the frame thus the wear?





I emailed DW and they said this is normal break-in. The accuracy is leaving alot to be desired right now on the ECO. The rental 1911's i fired had much better accuracy than the ECO.

Also this may be nothing but i noticed the crown of the barrel sits just outside the frame and is angled down. I looked at a TCP & ECP at my local store and the crown was flush with the slide on those or if it did stick out it was level.

The frame on my Vigil Commander did the same thing except it was even on both sides. I didn't care for it.

I just took apart three steel framed guns, a Wilson and two Dan Wessons, and they all have the same marks, but are all even on both sides.

The fact that its wearing in one side and not the other is concerning. Makes me feel better that steel frame guns show the same wear and your aluminum frame 1911 has the same wear. I am wondering if its actually a good thing. If one of the points of contact is out of spec it is essentially putting itself into spec. Should i remove the burr or leave it alone? I keep finding small aluminum shavings in the dust cover which must be from issue. I would rather not have the burr break off and be floating around while im firing the gun, might do some damage.

I wouldn't worry about the shavings or the burr coming off. They won't impede the function of the gun. I don't like the fact that the frames get peened like that, but it appears that it gets to a point and stops. My guns have thousands of rounds on them, too.

Went to the range yesterday. The gun definitely shoots left. Making very nice groupings centered on the bullseye but all consistently to the left. Backed up by 2 of the range employees. Don't know if the wear has anything to do with that, i hope not.

No other issues except it hates Magtech 115gr 9mm FMJ. Out of 10 rounds 3 of them had FTF and jammed the slide good. Measured the casing and they are ever so lsightly oversized compared to my other ammo.

I looked at my frame today while I was cleaning my Guardian. Mine has equal and even wear on both sides. My gun is very accurate though.

Seeing this prompted me to break mine down (it's my daily) and I have the same wear. Mine is somewhat uneven, but just barely, it's only upon close inspection that you can see the difference side to side. As long as you are having no other issues, I don't think I would worry about it.....

YMMV
