Dennis, All depends what you want to do. If you want a race gun the CZ Shadow ll. To conceal carry Sig P365. In reality you could ask 10 people and get 10 different answers. Example here is one list put together by a so called expert:----The 11 Best 9mm Pistols of 2019-2020
Glock 17 Gen 4.
SIG Sauer P320.
Smith & Wesson M&P Shield.
Head Down Products Custom Glock 19 & 43 RX-1.
HK Semiautomatic.
CZ P-10 Compact.
CZ 75.
Try a few and pick the one that works for you.

The best as in most reliable under hard use in the field in my experience were the SIG P226 and any CZ 75 or better yet the CZ85 Combat.
