they are a solid gun and the only 40 ruger has at the moment. It proved to be more popular than the ruger p-91 which was slightly larger. The 91 (ruger's 1st 40) fell by the wayside but the 94 stayed in production.
Hogue makes some rubber type finger groove grips for them that are nice. I believe they also still have some wood options.
From memory, once upon a time there might had been an 11 round mag but it disappeared during the clinton days and never came back. 10 rounders for this model are the norm. Big believer in staying with the factory mags and avoid after-markets.
Several outfits carry some things for the ruger. Midway USA is usually a good choice such as here for the mags

and here for holsters

ruger's on-line store should also have the mags and a few options as well.
My opinion, $375 for LNIB with 2 mags is good.....especially as nutty as the market is nowadays.
