Well I have some/many from a bunch of other brands, sometimes more than one example. The question was favorite brand other than the S&W. That answer is easy it is Ruger..
Dollar for Dollar Ruger is hard to beat. I have had a few pistols from them since 1972, a few different rifles including a very early .44 mag carbine and a 7722. Shot guns I have fired a couple and I liked them.
As a past range officer and instructor I have fired a lot of different Rugers and for what its worth they get my seal of approval.
My parents gave me a Remington Wingmaster 870 12 gauge when I was 13 years old. Been shooting them for 45 years now. I also have a few old H&R single shots including a 10 gauge. Nothing fancy about any of them but they have served me well.
I only own 2 brands of handguns-S&W and Ruger. Shotguns-Mossberg and Remington. Rifles-Ruger and Remington. I only buy Made in USA firearms, that is my choice.
