Titegroup might be smoky but you can get a lot of reloads out of a can, and most shops have it in stock. good call on the OAL but know that the 9x19 case is very compact and pay close attention to the OAL in the reloading manual. seating the bullet deeper into the case will raise the pressure very quickly.
One really needs to start with getting AOL right first, round has to fit in the mag and cycle action and bullet not to dig into rifling when chambered. Technically, AOL could be greater than SAAMI standard max of 1.169" but only if it works for your gun. Different bullets will call for different AOL.Then depending on bullet weight comes powder selection and charge. You use load data tables for starting point but keep in mind you don't want to be close to min and esp max load on the chart when you start. You check primers for flattening, you chrono the loads, you pay attention to cycling, ejection, recoil, flash, smoke and whatnot. I like low flash, low smoke, low recoil and a round on quieter side.
TG powder is very popular due to availability, price, low charges per round, easy to measure and consistent powder drops, I agree. On the other hand, ammo produces a little excessive smoke, flash, gunk and soot, powder burns relatively hot and can melt fiber optic front sight insert so it falls out if you shoot a few mags in a row at fast rate. My fav powder is Hodgson Clays for 9mm but it doesn't meter well in progressive presses. I loaded and went thru 40lbs of Clays, may go back to it. Also used Universal Clays, 700x, N340 and a few more.
After last jug of Clays went dry I gave TG a try and don't like it much. Now need to finish load development with True Blue, like it so far, recoil and noise are a bit greater than with Clays thou.
