if the metal can get hot enough from shooting to "soften" the metal in the slide, trust me, you wouldn't be able to hold in your hand as it would be way too hot. besides most of the heat is concentrated in the barrel, not the slide.
OP, if you look at the top of the barrel area near the chamber, it looks like that are is rough and needs to be smoothed with some emory cloth. the pistol is an economy pistol used for SD, not long shooting sessions or lots of target shooting. these pistols are not high on the list of quality firearms, but intended to be better than nothing if needed. if possible, try and save up and buy a higher quality pistol if you want to do a lot of shooting. you can even buy very good pistols used for a decent price if you shop around and there are many knowledgeable members here who will be glad to help with your choice.
