WHAT DOES HOW DO I BUY A GOCK 30 GEN 4 ONLINE MEAN?

They are chunky pistols. If I do get a 29 Will probably be a spread gun, not carry. We do have open carry in this article in Texas so I could have it OWB but I doubt that I at any time would mainly because of the body weight. These issues are certainly not mild either!Probably a dumb dilemma, but will be the 30s as powerful as the other variations
