Chuck - Not everybody likes the lines of Bren, but the CZ design has been copied the world over. I happen to think the Glock design is the ugliest thing going at the moment, but I would be a fool to allow that personal preference to effect my belief that they are also some of the most durable and utilitarian handguns available.
As far as comparing them to the current Ruger design... The P series from Ruger are EXTREMELY durable, and very affordable. Like most things Ruger, you probably get the "biggest bang for you buck" than with most other brands. But I would have to say that besides the Bren being a large weapon, they are well balanced, at least from my experience. If Rugers are anything, they are fat. Some of the thickest handguns out there, some have said. But as with most things, that's what makes living here in the USA great... To each his/her own.
Happy shooting!
Tamara - Its good to hear the 10mm is experiencing something of a resurgence. Your comment leads me to believe that my initial statement was at least partially correct. Unless the manufacturers believe the 10mm to be a profit making caliber, thus produce new platforms for it, the caliber will go the way of the dodo. I'm again glad to hear that the manufacturers are not deaf to what many are saying.
God Bless!
