This is an interesting comment. Why would that be a “no brainer”? What does it matter the category they put it in? The G45 has the same size grip as the “full size” G17. The slide is only around a half inch shorter, on the G45. The G45 isn’t easier to conceal, than a G17, it’s just more comfortable to sit down when using a straight drop holster. (And it has nice balance, which is a different discussion)
When compared to other makes, the G45 is the same size as their “full size”.
I don’t understand getting caught up on marketing jargon. The G45 is a “duty” size firearm. Not much different than firearms such as FN FNX/FNS, Sig P226/229, S&W M&P, etc. They were all designed to be carried into a fight. The G19 size is the smallest that really fits in the category “duty”. It’s also the largest that most people would consider for a concealed carry firearm. Even then, a lot of people find the G19 way too big, for concealed carry.
Now, someone will quote this and comment they carry a G17, concealed, and have for years. Of course, there are always outliers. Today, a large portion of the people who carry concealed think a G26 is too big. The tiny guns really reign supreme (in actual carry time) outside of LE/MIL.
I saw you were leaning toward the G45. Excellent choice. My response wasn’t just for you. People read these posts, for years.
