I plan on trying a USPSA match, but am not sure which Division I should shoot in. I would like to shoot my Glock 17 in Production Division. However, I have done two modifications to the gun: 1) installed Glock 3.5 # connector and 2) installed Dawson Precision fiber optic sights. So am I eligilble to shoot in the Production Division with this gun? Or what Division is the correct choice? Thank you.
