IDPA competition in the class I shot (SSP) used basically stock guns in 9mm. No race guns like IPSC. Almost everyone that was any good was using the heavier bullet combination. Nearly everyone was using the same powder at the time.... Titegroup
Every once in awhile I practiced with Winchester white box 115 and the 115 factory lods were definitely snappier. I competed for only a couple years and probably ran about 15,000 rounds thru my Glock in that timeframe along with lots of dry firing in my shop at night.
Very good training for self defense often with drawing from concealment and shooting center mass and sometimes head shots from a few feet away up to about 20 yards. Often the stages required at least one mag swap. Most of the time 2 to the body slicing the pie from concealment but sometimes 2 body and 1 headshot was the requirement.
To this day drawing my Glock and getting front sight on target then firing is as natural as breathing.
