+1 for US made brands
Of which, I own several.
Smith and Wesson is in the lead in my safe, and is most likely to be the brand most purchased in future.
Remington follows.
Then I have one each in flavors of Ruger, Kahr, Dan Wesson, and Fusion.
Of the foreign guns I own, I'll probably keep the CZ75B, and my mother adopted the SIG P239.
Trying to make room in my safe for more Made in USA boomsticks, and to raise funds for same, so if anybody is interested in a BAR 7mmMAG (1981, made in Portugal) or a recent vintage CZ75D PCR at reasonable prices, give me a shout.
As far as specific brands go, though, I have had favorable experiences with S&W customer service. Friends of mine had had warranty repairs done by both S&W and Ruger on guns they'd bought second (and bigger number) hand, after telling those companies that the guns were bought used. S&W and Ruger still repaired those weapons, quickly, for little more than cost of shipping.
That kind of thing will build brand loyalty.
