400 rounds fired. Who knows how quickly? Assuming that there are three 10rd magazines in the equation and an UPLula...I'm figuring 2 seconds a mag to shoot, 1.5 seconds to reload, combined with a thirty second magazine reload time gives 39 secs per 30 rounds. If I've done the math right that works out to 8:45 to fire 400 rounds. I think that would put the gun hot enough to maybe get into trouble. There were more magazines involved or something else entirely different occurred.
If you refer to my previous post, you'll see that I did exactly that. I only fired 300 rounds, but I had 8 10 round mags and used an UpLULA to reload the mags. I wasn't trying to shoot as fast as possible, but I was firing controlled pairs and doing emergency reloads when swapping mags.
I'm sure I was emptying each mag in 8-10 seconds with about a 1 second mag change. That makes for about 90 seconds to run through 8 mags.
Reloading a 10 round mag with the UpLULA takes about 10 seconds so, we can figure about 90 seconds for reloading all 8. But, I wasn't trying to set any records so, let's say it took 2 minutes to reload all the mags. That would be 4 reloading sessions with the 4th being shorter than the others. Even so, it couldn't have been more than a total of 10 minutes of reloading.
Combine it all together and my estimate of less than 30 minutes is probably pretty close.
When I was done, I put my gun in a pistol rug which encloses the gun more than a holster, and went home; about a 15 minute drive. There is nothing wrong with my gun and it still works flawlessly to this day. I've put at least 1,200 rounds through it since that day.

I believe that Donnieg3212 believes his gun was damaged through shooting. So, I harbor no ill will toward him and there's no need to bash the guy. I don't think he's a troll or other foul being. However, I do believe he's wrong about the cause of his malfunction. Based on my own experience I just don't see how the gun will melt just by firing.
Further, I'm sure that S&W has done failure testing of this sort. It's a common practice for a new design to be tested to failure. That failure point is a lot higher than 400 rounds.
Donnieg3212,
The advice to buy the new gun for $280 is sound. You can't get a Sig or any other gun for that price. Then just sell it and be money ahead. Doing anything else is simply using poor judgement.
