I bought the Performance Center model mainly because it was one of the only ones with a 10 round mag so there was no wait in my state. I needed it in a hurry for a major competition. I am glad I did, although I am not sure the 18" barrel is that much more accurate than the stock 16". Maybe a little. Need to try some longer range target shooting. I am sure it will not match my custom Remington 597 with its aftermarket barrel and trigger group. But as long as it is accurate out to 100 yards for the occasional tactical rimfire match I am happy.
