went to the range and tried something new. I filled the magazine to 10 on my pt-145 and started having misfeeds. Slide wouldnt go all the way into battery. After a few rounds the gun cycled ok. Before I would just load about five rounds into magazine. Gun is about 3 months old and now have about 200 rounds through it. Would you say the magazines are not fully broken in yet. Both mags did the same.
