The gun was bought new 8 days ago 7/22, serial JTGxx. I have shot the gun on two prior occasions with Magtech and American Eagle ball ammo switching back and forth without issue and very pleased. Total of 26 rounds the first time and 36 rounds the second time. Today was the third time shooting. I havent cleaned the gun yet(maybe a problem?), but have field stripped it twice after each previous day's shooting to simply inspect and reassemble. I planned on cleaning after today's shooting. I love this gun and was just about to fall in love with it- accurate/shootable and plenty of power for such a small package; but today's failure makes me worry --> ... Today, I fired one mag of AE ammo which fired normally and then went to the second mag of the same. The first round fired normally and ejected. The second round chambered, but when I went to pull the trigger, the trigger went all the way rearward without resistance(EDIT: except for the normal trigger spring tension). I released the trigger all the way forward again and tried again and again it went all the way rearward without engaging the hammer. I checked to see it had chambered a new round, which it had. I dropped the mag and removed the fresh round from the chamber and inspected the gun which all appeared normal. I pulled the trigger and it continued to go all the way rearward without engaging the hammer. I DID feel a very slight 'catch and then release' where it would normally engage the hammer. I did get it back working again after field stripping and working the trigger bar extension where it is visible, up and down with my finger. I just dont want this to happen again. I think the trigger bar was not coming all the way back up, but Im not 100% sure thats what it was. I think thats the only thing it could be. I want to completely detail strip the gun and clean and look at it. Is there a good guide for detail stripping this gun? Ive detail stripped Glocks and others before so Im OK with this, but a guide would help make sure I dont miss anything. Has anyone else experienced this problem? What are some things I should look out for? Thanks!
