If you're able to find a place to rent/fire a variety of guns, I recommend you try the Ruger SR9 or SR9c. Most comfortable (for me) and best shooting 9mm I've ever owned. It's the only gun I've used that I can reliably do the following with:
- pick a random aiming point 10+ yards away
- close my eyes
- raise gun at arm's length and try to target my selected spot
- open my eyes and be either dead on or within a fraction of a degree
I guess that speaks well to how well it fits my hand/body. Glocks never have felt comfortable to me (grip angle is all wrong).
I've put more than 3500 rounds through mine with no real problems to speak of... 3-4 failures to eject (mostly lax moments on my part but one was a squib) and 3 light strikes. The light strikes went away immediately after I cleaned the striker and channel (a little excess lube had collected on the striker and it was catching brass flakes/crud.)
