The best way to shoot lead in a Glock IMO is with an aftermarket barrel. Better suited. Some use a .357 bullet rather than a stock .356 in the 9mm. The slightly larger round makes a snugger fit and more accurate. But a square peg in a round hole may fit with a hammer but it is fits better with a round peg IE the aftermarket barrel I suggest.

As far as jacketed why not try plated? Much cheaper and just as easy to load as FMJ. Just be sure to not overcrimp as the lead is softer than the cast bullets and crush easily. Doing so can also cause the plate to separate. Use the cast load data or the medium load data as the max.

Another thing to keep in mind (depending on the model) case swelling has been associated with the Glock barrels. might want to ask someone in the reloading section about which models have the issue. Another thing that an aftermarket barrel solves is the swelling if it is associated with your gun.
