Years ago I decided there were some 9x19 handguns I wanted to own just to own one. G17, Hi Power, Berretta 92, etc. I don't think there is anything wrong with adding a gun just to own one. I like having lots of different handguns and being able to compare and contrast them. I of course have my go to gun and my favorites but nothing wrong with owning a variety. I have six or seven different makes of 9mm pistols. Within them I have full size to sub compacts, different designs: striker fired, DOA, DA/SA, metal and polymer. I like having a variety. Its also led to be being pretty amused when people act like one brand or model is head and shoulders better than everything else.
In sum, if you want the glock, get it.
