I had a problem with a 1911 when the slide stop backed out while firing the weapon. Another forum suggested that the cause might be a dirty or sticky plunger tube. Can anyone please comment? Load was a 230gr cast bullet with a moderate powder charge.
Problem with 1911 slide stop

There are a number of things that can cause that.
1. Weak plunger spring
2. Pushing the right side of the pin while shooting the gun (it doesn't take much)
3. A worn out slide stop (It happens-- wearing down the diameter of the pin due to the friction of the barrel link)
4. The magazine can be deformed putting pressure on the pin.
5. A damaged or deformed barrel link.
Start with a plunger spring.. they are $2.50

I am confused as to how this is possible.

This is not an uncommon issue.
The most common causes come down to a poor fit of the mag to the frame or a plastic follower.
What is happening is that the mag follower is sliding up past the slide stop protrusion. The left side of the follower is putting pressure on the slide stop. When the notch to remove the stop goes past the stop that pressure pushes it to the left.
If you have a mag with a plastic follower look at the side of the follower for a groove that starts at the stop plate area and goes down the side of the follower.
Replacing the follower will cure the issue, but you may as well buy a slew of followers because it will happen again as soon as you've pushed the follower past its plastic vs. steel ratio.
You did not say what kind of 1911 you are shooting or what mags you are using, but I'd be willing to bet $20 you have a plastic follower. In a single stack switch to Chip McCormick mags. In a double stack, buy a bag of followers. First sign of a hiccup replace the follower.
I buy them by the 10s for my double stacks. Some only go three or four mags and some go for a couple dozen. It is just part of the cost of shooting double stacks...

I would also suggest looking at the plunger tube spring. I also had a 1911 where the bullets would hit the slide lock while chambering.

If this has happened only once, it might have been a fluke. In any case, number your mags, ans keep track of which is in when the problem happens.

I had this issue when using hollow points. They were starfires. I went back to ball, no issues.

I had the same thing happen. checked the follower but
there's no notch on amn of the followers.
S&W 1911 5" Stainless Steel
Wilson Combat ETM mags. gun has
close to 2K rounds through it.
I was looking at EGW slide stops either .203 or
.201 pin diameter available - I was thinking of the
larger, and it can always be sized to fit.

If the slide and the slide stop are made properly, there is only one point at which the stop can move out, and when firing that point goes by so fast that the stop will not move unless physically pushed. But with some badly made slide stops, or badly made slides, the stop can move at any point in the slide movement.
There are several fixes, including cutting a groove for the slide stop plunger, but they are all cures for what should never be a problem. The old rule still applies: Junk does not work right. If you buy junk from people who think specs are for suckers, you get what you pay for.

I have had this problem when shooting left-handed and my right hand thumb pushes against the frame (as part of my normal grip) where the slide stop pin protrudes. I stoned down my pin until it was flush with the frame on my primary gun, but have had this happen with several guns and shooting left handed.
