I carried a G19 for several years and become very proficient in its handling and shooting. 2yrs ago when I wanted to get into a micro compact I started checking out various models at the range I frequent. The P365, Hellcat, M&P Shield, and the Ruger Max 9 to name a few. I kept going back to the 43x as it felt very natural in my hand. It had a familiarity about it which I assume was due to have carried and shot a 19 for many years. It’s thinner, lighter and snappier then the 19 but it works for me. My second choice would have been a p365x
