The handguns you mentioned are all good guns. I think you should try them all before you decide. No one has brought up the S&W, SD 9. It started life as the Sigma, but is now on it's 4th. Gen. It is alot like a glock but has better ergonomics. It costs less & is very reliable & accurate. It is about the same size as a glock 19 & holds 17 rds. Because of the problem with your hands I feel you might want to try it. It is more comfortable than the glock to hold & I have not seen any major complaints other than the trigger. If the trigger is a problem its a cheap fix. I have owned & shot glocks since they came out & believe they are great handguns, but when I grab a 9mm now, it is most often my S.D.! Check one out.
