I bought both 4.25 & 5 inch models w/o optic. I took them to the range today and was greatly disappointed. First few rounds out of them felt great, then I had nothing but feed and magazine issues. I shot 250+ rounds out of both, I shot Remington, Federal, Winchester, Sig Elite, Sperry Gold Dot - 115g, 124g, 147g standard and +P, FMJ and JHP and it just did not matter. Out of the 500 rds through both, I had well over 150 fail to feeds. I also had the follower in the magazines get stuck half way and literally could turn the magazine over and rounds fall out. Felt like I was shooting a 22LR with rounds nose diving in the magazine but that was with both the 17 & 20 round mags. Took both back to the LGS and their gunsmith looked at them both and the videos I took showing the issues. They took the magazines apart and the follower was getting jammed in the mag tube, the mag spring was not very strong. The cleaned up the followers so they do not catch now in the mag tube but no change to be honest. I have sent Springfield 2 emails and waiting reply and the LGS is calling them on Tuesday after this holiday weekend to see what can be done to fix this problem. The 4.25 refuses to feed JHP out of any magazine I use, I can rack one in and FTF the next round every time. So for now they are expensive paper weights as I can not trust either one to run if I need it to. Biggest disappointment I have ever had with new out of the box firearms. I was so made I told them take them back and give me the Sig 229 Legion and X-Macro, I know they will run and be dependable. Amazing how all the "Gun Tubers" guns run flawlessly and you get one and issue after issue. Springfield has one chance to make things right or they are gone!
