In my area, it is actually easier to find parts for the HK than the CAR 9, but, of course, the parts are very, very expensive!!! To get the HK spare parts you have to go to the higher end dealers, but at least they are available... In my opinion, the HK is a better model in terms of fit and finish... The CAR 9 was more of an after thought to adapt an AR .223 to fire 9mm, hence the pinned mag well adaptor, which seems kind of cheap looking considering the price of the CAR 9. (perhaps it is cheaper in your area, but a pre-ban CAR 9 in Southern California will be about $1800! Although, the HK 94 is over $4000! Yikes!!!) If price wasn't a consideration, I would most certainly go for the HK (more prestige and "wow" factor in my opinion), but for twice the cost, is it worth it? That is something only you can decide...
