If you were to get a standard 9mm conversion, convert to DA and remove the mag well, you might get a hassle at Nationals, but since it would be almost identical, yet technically inferior to the Stock II (let's not even get started with the new, cone barrel Stock III which is basically a DA Limited with added weight at on the frame...), I bet you could shoot it at the local level all day long.
Production (practically, but not technically), L10, Limited, and Open.
