I currently carry, shoot and reload for the 9mm in a G19. However, I am considering purchasing the G32 to replace my G19 because of all the great things I have read/heard about this round as a self defense cartridge. Since I don't reload for the .357 and really dont want to start, I am wondering if I can practice using my G19 with full power loads or can I convert the G32 to 9mm with a barrel change and fire full power loads for practice. Obviously nothing is as good as practicing with the round you will be carrying, but I wonder if the difference between full power 9's and .357's is great enough that I should start relaoding for the .357. I hope this question makes sense.
