I am sure you will get many helpful words of advice here. Let me ask you a few questions to narrow down the vast array of choices, it may also help you identify exactly what you are looking for.

What do you want to use the pistol/revolver for? (defense, hunting, plinking, target shooting. . . .)

What is the most important aspect of your ideal handgun? (price, accuracy, ease of use, recoil, $$$ per round, ballistics. . . )

Best of luck and enjoy!
