Not trying to undercharge the round. Rather I am looking for insights into the various powders - to see if there is a load and a powder that provides a 100% powder burn for a 3.3 inch barrel, versus the longer barrels of my full size Sigs.

Thanks.

Do a search for a powder burn rate chart and print it out.

Figure out what weight bullet you want to use, check your load data for the loads with the faster powders from the chart.

I shoot the same commercial ammo through my short barreled Glock Model 36 as I do the compact Model 30 and the full-sized Model 21. No problems encountered.

Doesn’t all the powder burn regardless of how long the barrel is?
