My very first classification was 'B' in USPSA, but just barely. I had been shooting a LOT of GSSF so shooting itself wasn't a problem, and I had been doing some IDPA. I practiced a lot of dry fire on draws, as well as mag changes. Classifications don't usually have movement involved, and I went to a "classifier only" match early on where I threw down several high 60's.
My 3 other buddies all started at C, however one of them is already an A, whereas I'm just below 70.
What division are you shooting? I was out of USPSA since around 2004 and got back in last year, 2012. Was D in Limited shooting minor and after 2 or maybe 3 classifiers I'm now a C. Started shooting Production last month, currently a U and want to come in a B but it may be C. Congratulation!
I shoot Limited Major with a Gen4 G35, a couple of matches ago I got a CR Speed holster, trigger spring kit and two mag extensions and a Dawson ICE funnel. Still need to get some mag pouches, as Im using the old factory glock pouches till then.
