Hi, looking for some advice please!. I purchased a new BT 380 cleaned and lubed followed all guidance in manual. 2nd to last bullet in mag takes an upward nose dive every time and gets stuck on inside top part of breach. These are the steps that I have taken to correct this issue to no avail... 1. Purchased another magazine....still has FTF prob. 2. Ensured grip was proper every time.. 3. Changed up ammo brands. This is aggravating considering this is a new firearm!
