I own a 9mm JR Carbine and have ran over 800 rds through it of 115 grain w/o a single malfunction, however when I first started testing different ammunition I found that 147grain (Winchester) with a slightly more abrupt edge on the casing shoulder caused a feeding issue so now I avoid that particular brand/type/weight (Could be a similar situation to what Ted Dent mentioned?),,,
I really do not think you will be disappointed in a 9mm JR Carbine but unfortunately I cannot speak of any other similar firearms from personal experience (it may not be applicable to your situation but 9mm JR Carbines cannot use +P ammo, at least w/o modification but I cannot speak accurately on the topic regarding modifications to accept hotter then standard 9mm rounds in a JR Carbine) I'm sure others more knowledgeable on this subject then I could chime in,,,
I have begun modifying mine and I like it more and more after every upgrade, I would take that into consideration if you like tricking out your firearms as the JR Carbine being that it uses AR parts offers unlimited modifying opportunities at relatively reasonable costs,,,
The good thing is you probably can't go wrong with any of these types of rifles that have been mentioned and if you want to trade/sell for a different model later on it shouldn't take long to make a deal/sale, however staying with a non~restricted model probably would be best for a quicker resale and then you could go plinking other then at the range too,,,
Good luck getting your 9mm Zeroed In
