I'm thinking about getting a 9mm carbine to use for 3 gun matches and also for the fun of it. The the ability to use the same cheaper ammo I use in my pistol is appealing to me from the just the logistics of only needing to order one style of center fire ammo seems like a good idea and most of these matches don't have super long shots anyway so any sacrifice in range vs a 223 gun would really be negligible for my intended use.
I started off looking at the Beretta CX4 Storm in 9mm and there's a lot to like about it but it seems that people either dislike or outright hate the trigger and the only after market trigger puts the price of the gun right into 9mm AR territory assuming I buy new. So I started looking at the Lone Wolf Complete Lowers and matching upper in 9mm because I already have a bunch of Glock mags and since I shoot a glock in matches it would really make going to matches super easy so that makes the 9mm AR very very appealing too but I remember a lot of people having lots of problems with 9mm ARs in the past and I don't know if that's still the case.
After comparing the pros and cons I literally cannot make up my mind; I just keep going around in circles. So anyone have any experience with either and care to offer up some input?
