Here is the V2 of my PPK Knex model. It shoots pretty good, and it is WAY easier to pull the trigger. It just looks better, and it is easier to pull the trigger. And the back where the handle meets the barrel, I made that different too. I added sights, and they might be the best sights I've made so far. So there's not much else that I changed. And it may look like its a removable mag but it's not and the orange part is just for looks.
