For those who have not shot a formal subgun match, I can't think of a better one for your first match. This one is very relaxed, low key. It's more like a bunch of friends putting out some targets and running it for fun & bragging rights.
And you have a good bunch of folks there who will answer questions and help you out.
In the past there were no mag limits (big mags, drums, etc. run what you brung).
Unfortunately I won't be able to make it this time. Hopefully in the fall.
Have fun!
