You can't - you'll have to spend 3 points in Shockwave to unlock Pull. It's impossible to max Jack's passive, ammo power and pull.
Unless you mod of course.
Though frankly even if you do neither Jack or Jacob can hold a candle to Samara even with the Geth Shotgun in their hands. I mean with Samara you have pull, area reave and throw and she has an assault rifle and an SMG. And for that mattter Miranda can use slam to set up warp combos and she also has warp, overload, and a passive power which boosts the whole squad's weapon damage.
Having a decent shotgun makes Jacob and Jack more useful than they were; but on hardcore or insanity they're still pretty damned useless simply because their power set sucks. I mean Grunt is a far better tank than Jacob and he also has incendiary ammo as well as concussive shot and Samara (pull), Jack (pull) or Miranda (Slam) are all better options when it comes to setting up warp combos since the cooldown on Jacob's barrier means that his bonus power undermines his ability to cast pull. If all you want to do is spam pull then Jack is your best bet; but her slightly faster cooldown hardly makes up for lacking Samara's area reave or Miranda's warp and overload.
Even with a better weapon in their hands though Jack and Jacob are still far and away the most worthless squad members in the game.
PS: The Geth Shotty is a freaking great weapon for Tali though who is great against any synthetic or shielded organic and an absolute beast against Geth.
