While I certainly have "brands" and/or models that I prefer, such as Springfield Armory (XD40SC/XD45ACP) or Sig Sauer (P220/P226/P239), I would not necessarily say that I am "loyal" to these, in terms of simply dismissing all other contenders.
It just so happens that, up to this point, the previously mentioned brands/models have met my needs and expectations over the years.
Generally, it depends on which caliber I am wanting at the time, along with how the weapon is to be used. From here, the comparisons begin.
When in doubt, I will purchase SIG pistols. However, their change to American manufacture makes me wonder if they are the same. I do not own any American made SIGs.
From what I have gathered, not all "current" Sigs are bad. It really seems to depend on which model one purchases. Sure, I won't argue that the new Sigs compare to the older models, but I would not write them off completely.
The newest Sig I own is a 2008 model P220. I have yet to encounter one issue with it after hundreds of rounds. It shoots just as well and is every bit as reliable as my 1993 model. Of course, I have yet to fire the "latest" Sig, so maybe things have substantially changed since even 2008. I dunno...
