Looks like a pretty good gun especially the Long slide version..
if the gun fits you and you shoot it well..it will do great..
seems to have features of lots of other guns that do well in USPSA and IPSC production..G34, CZSP01, Smith M&P, SA XD Tactical, SIG226.
so lots of choices..
9mm is great because of all the low priced ammo you can find..have been told .40 can be real soft at the lower power factor too..
have fun...it is a great time
