Will,
USPSA is just like IDPA (sort of ) without the reload and cover rules. You’re CDP and they have a SS (Single Stack) Division that your can use your IDPA equipment in (or a Limited 10 if they don't offer that)
You will need your gun and five or six magazines along with magazine holders. I just happen to have the extra magazines and magazines holders you will need.
You should see some really good shooters like Dave B. and Scott B., from the New Bedford club, shooting unleashed along with a couple of guys that you haven’t seen yet.
Manville is a good place to start if you would like to try it. I'd be happy to shoot with you if you'd like. Let me know.
Or you can go shoot CAS (or watch if you don't have the Cowboy equipment) with the Bass River Boys down the cape, they're a great group of guys.
Respectfully,
jkelly
Sounds like fun, though I get the feeling it's outisde my 'one hour max' driving range for such things, though I would have to look at a map. I can muster as much as 4 mag holders, 1, 10rnd mag, and 4, 8 rounders.
