This MAY be a possibility, I never really paid attention to how close my thumb is to it. I will have to take notice next time Im at the range.

Was it an actual FTF, or was the slide stop getting bumped or catching somehow?

Now that I think about it, I'm not exactly sure if I was bumping the slide stop, or if it was an FTF. I'm still thinking it was a bunch of FTF's, because I had to pull the slide back more than if it was just locked back from where the slide stop is. I guess I will have to go shoot it some more

and figure out whats going on based on what you guys have told me.

This would only explain if the slide was actually locking all the way back. His description doesn't say this. He says the slide is sticking partially on its way forward to chamber the new round.

But if it's just a bit crooked, it screws up the slide movement by binding weird, and that slows down the slide---leading to problems feeding and ejecting. Field strip, make dead sure the guide-rod is properly aligned, and you should be fine.

This is a more likely scenario. Something is taking the inertia out of the slide on its way back into battery and not allowing it to fully feed the next round.

This is the key part of your problem. The slide is being stopped before it goes back into full battery. This could be, as mentioned, a misaligned guide rod assembly, ammunition or magazine issue or even the possibility that you are limp wristing and taking the inertia out of the slide action.

Bet it is the marginal magazine springs and the design of the .45 version of the XD causing this. The extracting case impacts the top round in the mag and drives it downward. If the spring is marginal it can't reposition the round before the slide returns to battery. Usually the round nosedives into the forward lip of the mag not even reaching the feed ramp. Pull back the slide, mag spring them correctly positions the round, release slide, it feeds just fine, and all is well - for that shot.

Lots of threads on this, which seems to be an issue with the .45 only and perhaps some lots of mags with weaker than normal springs (I am guessing at that last part). The solution is replace the mag springs with those from AGP which are 20% stronger. The issue seems to go away then. Cleaning the mag may help some, but new stronger springs are the real solution.

This is also why the .45 won't feed SWC, but the springs won't fix that.

This is exactly what I think may be happening, thank you for the excellent explanation. I will try out the gun 1 more time as is, and if I have any problems I will try new mag springs. I was reading some people send their gun in to springfield armory and they polish the feed ramps which is also supposed to help some, but the mag springs seem to be the most popular way to go from what I've read on here.

The AGP springs are awesome. Definitely worth the $7 to $14 for 1 or 2 of em. May be the cheapest fix to a major problem encounter by a lot of people here, other than the .20 cent roll pin!

A thorough, real thorough, gunsmith thorough, cleaning may be in order. I use a very thin layer of white lithium grease on the bearing surfaces of all my guns and that solved the problem for me.

AGREE!
My guess is a gummed up spring, extractor or ejector due to bad oil. Taking it to a gunsmith is another good idea. A gunsmith can do a complete tear down and make sure ALL the parts are cleaned properly.

Another thing you may want to do is check your magazines. Most feeding failures are magazine, NOT gun related. Take your magazine apart and check the springs. Also look for any cracks or deformities in the magazines.
