I also own and use a Ruger P4R (with ghost ring sights). It is chambered for .40 S&W and uses the same magazines as Ruger' s P94. It is a great little carbine but the price is much steeper than you were originally considering. However if you have raised your ability/willingness to spend more....then consider the nice Ruger carbines. (Not to mention their .44 semi-auto as well).
