My choices of those that I have experienced are:
1) CZ-97B, Bought it based on satisfied owner comments, price, quality, 10 round capacity, and reliability. I'm very happy with it. The trigger smooths up nicely with live and dry firing. Not a lot of accesories available, but more forth coming as the gun is gaining popularity.
2) Glock 21, This was the first runner up. About $ 50.00 more O.T.D. than the CZ. Good accuracy, high 13 round capacity for pre-ban mags., and very reliable. The grip just felt a little thicker in the hand than the CZ. Lots of accesories available.
3) Sig, P-220. Excellent gun with the sweetest trigger in the bunch. Kind of expensive new or used. Lots of accesories available.
4) S & W 645. Nice gun. Accuracy was fairly good, and the gun was solid. Trigger was o.k., not as smooth by a long shot as the Sig or CZ. Bought mine used for $ 350.00. For the price it was very reasonable. The current models are kind of pricey NIB. Accesories readily available.
