I recently purchased a colt commander and have been experiencing reliability issues with it since the first magazine. The gun can fire between 4-5 shots before the gun fails to fire. The hammer will go froward however it doesn't strike the valve. After removing the magazine, it became evident the firing pin was striking the top of the magazine instead of the valve. Does anyone know what would be causing this?

Some additional notes:
- I was firing indoors
- The problem occurs even while dry firing (I have to hold the slide catch)
- I have tried two different magazines and the problem still occurs.
- I have field stripped the gun after the problem and reassembled and the problem still occurs
- If the gun is tilted upwards significantly it will fire reliably (I did this without ammo for obvious reasons)

Does the problem continue when you remove and reinsert the mag?

The problem will continue if I remove the magazine and reinsert it.

I can fire about 4-5 shots, then the gun fails to fire. I have to cock the gun again and I will get another 4-5 shots before the problem occurs.

I had a similar problem with my G&G airsoft pistol. I found that when I fired it rapidly, after 7 or 8 shots, it did the same thing yours does. Slowing down the shots cured the problem....but took away some of the fun. Never figured out why it did this in the first place.

I don't think that is the issue I am having. During this entire process I waited at least 5 seconds between each shot and it doesn't seem to change the results. That also wouldn't explain why the gun will shoot reliably when it is tilted up wards.

Maybe the striker has backlash? Have skewed and striker misses the valve. When you turn the gun upward, than the striker stay in the correct position

Do you hear any rattling when tilting the pistol upward?
Is it possible that a BB is stuck deeper in the pistol, that field stripping won't release?

I just started to get a similar problem with my 1911 and have a solution.
My problem was that the striker was disconnected from its return spring. As a result it just floated around. If it happens to be in the wrong position, it won't strike the valve release. Holding the pistol upwards, lets gravity put it back into the correct position, which is why it reliably works in this position.
Unfortunately the fix requires a complete disassembly of the frame. However, Chiinnature has an excellent video that takes you through, this step by step: https://www.youtube.com/watch?v=olkMIATlF_c
The last large assembly removed from the frame has a smaller assembly with the striker within it. It was fairly easy to put the dangling spring and insert it into the slot of the striker, but do this in a plastic bag!
Problem solved, just carefully follow the reassembly process in the video.
I'll post some pictures soon.

Here is a diagram. Note that the fix and problem is applicable to all the KWC 1911 blowbacks - Colt Commander, Blackwater, Tanfoglio Witness. Swiss Arms 1911, etc

Thanks for the image, I did find that to be the problem with my gun.

Good to here. I found that what caused the problem for me was inserting the magazine when the slide is not racked back.
