I bought a Ruger LCP on 10 April and ran 38 mags of Lellier & Bellot and MagTech ball and two mags of Cor-Bon JHP over several days. Experienced no problems whatsoever. Yesterday (12 May) there was a complete failure of the magazine to insert. It simply would not go in normally past half way. The only way to inset the magazine is to manually depress the release button, then it inserts fine. Magazine looks fine, no rough edges or damage. I put in a call to Ruger and am awaiting a tech reply. Reply from Ruger: "The top edge of the magazine contacts the bottom of the magazine latch and forces it to the side so that the mag can be fully inserted and locked into place. Sometimes the magazine catches the bottom of the mag latch causing the condition you described. If you insert the magazine and bump it hard into the pistol with the palm of your hand and repeat this a few times, the condition will go away. Don't be afraid to do this, it will not harm the pistol or the mag latch. We have never seen a mag latch fail on the LCP." I did this, hard, several times, and the magazine now inserts fine every time.
