Hello Glockers, In order to really practice my "defensive situation" skills I will be joining IDPA. My first match as a new shooter will be this Thursday if all goes well and I am wondering if my G21 will be okay for this? I also have a G30 I can use. What are your recommendations? I would like to use the G30 but at this time I feel more comfortable with the G21. I know they have a specific "class" for big bore "Custom Defensive Pistol" for .45 ACP so this is what I will be registering for. Feedback and suggestions welcome. Thanks, Mr. Ironhead - Practice, Practice, Practice!
