Well, the way I see it is like this:
1) Silvertips for handgun cartridges come in two flavours: those with grooved jackets and those without.
2) I have never seen a Silvertip that had a grooved jacket, where the grooves didn't go all the way to the rim of the hollow point.
3) The rounds in your picture have grooves that don't go all the way to the rim.
And that's why I reckon the rounds in the first picture cannot be Silvertips. They also look a little lacklustre to me, which indicates they don't have the required jacketing.
