I noticed something a little "off" today.

My carry gun is a Colt Delta Elite (1988). This pistol has had a small amount of work done on it. No more than "smoothing" a new pistol. I noticed something with the slide today and it got me a little worried. I've only shot 500 rounds through this gun at most. I don't see any other wear corresponding with this wear. I've never seen this on a 1911.

I would watch it and see if it changes over time.

There are a couple of possibilities I a can imagine.

It may have been that way from the factory and never noticed before now.  Seems unlikely, but I have had this happen.

The second thought that occurs to me is rebound.  The thought here is the increased slide velocity of the 10mm auto is causing the hammer to rebound off the frame past full cock and hits the slide here as it travels to the rear.  If this is the case a flat bottom firing pin stop may help.

The other ideas seem very unlikely as they would be the result of a slide that was quite substandard and probably would manifest other issues.

I would add that I have seen various amounts of wear in other 10mm pistols in similar areas.  The firing pin stops in my EAA guns tend to "draw" some steel both over and from the slide where they meet, resulting in some difficulty in removing the stop.  Seems like I have at lease one gun that has a similar deformation, though I can't recall which at the moment.

That is odd.  That's the notch that the disconnector sits in when in battery.  Can't say as I recall ever seeing much wear there.  How much play is in your disconnector?

Suspect Sqlbullet diognosis is the right one. 

Drawing a blank as to where, but recall reading somewhere that some Colt Delta Elites with 22lbs recoil springs suffered from hammer wallering out the slot it rides in on bottom of slide when cycling.  Don't have any other details.  If that's the issue, hopefully there is a simple fix but I'll defer to others. 

Good luck.

When the pistol was new I took it to Ace Hindman in Kerrville, Texas to do some work on it. He installed a new trigger, guide rod with 26 lb. dual springs and did some polishing. Since then I have went to a single 26 lb. spring and the pistol has always cycled perfectly when using the original Norma 200 grain ammo (675-705 Ft lb.) or the equivalent. Do you think the spring tension is the problem?

I really doubt it.

Did he mess with the mainspring at all or just the recoil spring?
