While it is not for me I do like the fact that Ruger continues to innovate and release new products. This week they announced a new version of the GP100. This one chambered in 10 mm:
This is a big revolver weighing in at 37 ounces. It has nice sights and some other features that are (I assume) geared towards competition or target shooters. If you like big, heavy revolvers chambered in a powerful semi-auto cartridge this might be for you.
Take care and God bless.
