They are certainly homely, but pretty is as pretty does and they do flat out work.
I like that they are pretty much totally built around function with style being a non-issue for the design. It's a chunky brick of black plastic that goes BANG when you need it to.
Still, not my cup of tea. I think that pretty much everyone else making poly guns makes a better looking one. M&P, SIG, FNH, H&K, etc are all more handsome. I will say that I probably prefer the looks of the Glocks over the Ruger SR series. I just don't find them an attractive pistol at all.
