I love bacon...but I would recommend the Glock 26 with a model 19 magazine and an A&G Grip Spacer, giving you a full-sized grip, but without the heel dig that compact and full-sized Glock grips give you.
Seriously, though...if you're considering a 9mm...would a .40 be a better choice?
Some really good advise and recommendations here, but if I read your post right, I think you are saying that the .40 is a little more recoil than you're comfortable with. I'm not sure that going to a 9mm in a smaller package is going to fix the problem. Going to a smaller gun is not going to fix you're "tracking" problem. I would suggest that you shoot a 9mm G19 and that might answer all of your problems. If that works then you might look at one of the various subcompacts.
im a fan of xd or xdm in sc for 9mm.you should try a few for yourself to see what you like,like others here if you have a g23 just put the 9mm kit on it and carry it.each to their own.
