I’m shooting a USPSA match this weekend and wanted to shoot my stock Glock 19 with TLR-7 and high cap mags. What class should I register under?

All USPSA pistol divisions allow the use of weapon mounted lights. I shoot a Glock 19 with weapon light in production, but I like to reload.

USPSA Rule Book

Edit:

Missed you wanted to also use "high cap mags"... Limited Division is probably where you want to be. No limit to the number of rounds in a magazine, but a maximum magazine length of 5.561” (141.25mm).

Cool, thanks for the clarification.
