Among the trends we have noted over the past decade is the replacement of the snubnose 38 Special revolver with the slim-line 9mm Luger pistol. Pistols such as the 9mm Smith & Wesson Shield and Glock 43 are the most popular pistols for concealed carry these days, but SIG took the platform even further with the SIG P365, a 10-shot 9mm with good reliability and practical accuracy. Other makers followed suit, including Smith & Wesson with the Shield Plus and Ruger with the Max 9. In this installment, we match up three comparable handguns, but each with different features. These makers have managed to stuff as many as 17 rounds into the magazine. Two offer a flush-fit magazine for pocket carry and an extended magazine for holster carry.
