I'd google reviews of local courses.

Also, this is gonna sound stupid but alot of people swear by airsoft guns for training. Specifically indoors. It's alot of cheap, safe, quiet trigger time. They make airsoft guns replicas of most of the common handguns so practice manipulating the controls (safety, slide release, mag release, etc) transfers much better.

same basic design for 20+ years while tastefully refining it through 4 generations. Super durable, and reliable. Massive aftermarket and spare parts market. Will accept glock 17 magazines and the 33rd glock 18 mag. (I get funny looks at the range with the 33 rounder haha). Handles +P ammo just fine. Super low maintenance. etc etc.

Source: I tried XDs, sigs, H&Ks, CZs, etc and decided on the glock 19 for my everyday carry gun. Don't regret it one bit. And oh yea, it will fire a whole mag under water no problem ;)
