I bought the gun new about 3 weeks ago and fired it about 2 weeks ago. Shot 250 rounds through it without any complications. I cleaned the gun but did not completely break the gun down because it was no where near the number of rounds that the manual suggested break down for. I went to shoot today and the slide gets stuck when chambering the first 3 -4 rounds, you have to push on the back of the slide to get it to chamber the round. If I only put 4 in the clip it chamber smoothly. Also when I'm chambering the first round it sounds like the springs are catching on each other. Any suggestions?
