This is your opinion, which you are certainly entitled to.In the world of carry and duty guns extra weight is a disadvantage.
In my opinion and in my world of carry and duty guns, any handgun not made of steel and in a minor caliber is a disadvantage. I am not currently on-duty, but tomorrow nite I will be, and it will be w/ a steel, 5" 1911 in .45ACP that gets 200+ rounds fired thru it each week in training. And I consider myself to have a distinct advantage over anyone I come up against. I also carry a Commander-size 1911 off-duty, but do not notice any "extra weight" w/ either weapon.
