Hey, no problem...
I'll chalk it up to being just another one of the many defects found in the Chevrolet Vega. I hope you're old enough to know what I'm talking about...
Here are a couple of other potential causes of smokestack jams...
Recoil spring is too weak for the ammo being used.
Recoil spring is too powerful for the ammo being used.
Magazine problem that allows rounds in the magazine to interfere with casing being ejected.
Not enough lubrication.
Lubrication is fouled.
Fleem rays from the Planet Skorbax.
That last one is a real pain, because you've got to pay a LOT of money to have a defleemulator mounted on your gun.
The point of this is that there are a LOT of reasons for a 1911 to smokestack.
Limp wristing, and the ones I've mentioned above (with the exception of the magazine interference one), involve the slide moving either too fast and coming back and catching the empty casing before it has time to clear the port, or the slide doesn't recoil fully and allow the case time to clear the port.
