I was going to do a search for this topic but the search engine is currently listed as disabled. I'm considering joining the local IDPA group, but I realize that my G19, which is a great carry gun and range gun, may not necessarily be the best choice for competition. I just bought a book that rates the relative competitive range effectivess of the Glocks, rating the Glock 37 much higher than the G19. My problem with the 37 is that the 45 GAP round, which I've never shot, could prove too much of a novelty round. I like 45 ACP, but not in the available Glock model (too large for my hands). Any opinions/suggestions on all this?
