This is a great option for those defenders who prefer the ballistics of the 45 Auto over the other calibers listed here. The Glock 30 is a sub compact 10+1 round 45 Auto pistol. Here are the stats pulled from their website on the G42: 1 (Here’s a concealed carry gun belt review she did for us.) That’s her gun pictured and the photo credit is hers also. I have not carried a G42, but my good friend Eve has. This is, as far as I can recall, the smallest Glock pistol out there as of this writing with a magazine capacity of 6+1.īecause this is the only 380 ACP pistol Glock makes at the moment, there is no magazine interchangeability. 380 ACP guns, the G42 is the standard by which all others are measured, and rarely does anyone come close.
