I like the CCW segment...it provides a good initial primer for evaluating guns for a beginner...but he does need to add an item or two (weight, reliability, ease of maintenance).....
Seeker,
You have a good point, but these items are more subjective than even the other items he rates. Mr. Potterfield's time to first shot, and number of shots on target are only consistent because he is the one doing it the same way for each gun. As said in many commercials, "Your actual results may vary."
The items you mention are have more variability than what he is testing:
Weight - Just like size in a carry situation is going to be more a matter of size of the person. I joke because I carry a a full sized 1911 and have no problems. I will actually put a 5" 1911 on my hip and a j-frame in my pocket, and go unnoticed. However, there are people out there that can't hide a KelTech or Ruger .380 under a parka without it showing or weighting them off balance;
Reliability - At one point I heard him explain in an interview that it is a given that any of the items he rates is going to be reliable and durable. He leaves these rankings to the testers that go into that;
Maintenance - This is a personal practice item. Once you decide to carry and use a gun it is up to you to maintain it. Once you learn how to do something it is easy. I can tear down, clean and lube, and reassemble my 1911's so fast it will make your head spin, but I an hardly get the slide off my M&P and XD, because I don't do it that often. Others can do the "tupperware" blindfolded, but they don't know how to start on a 1911.
All three are good points, but that is where you as a gun owner and user need to evaluate your own preferences.
