zipollini Posted November 6, 2016 Share Posted November 6, 2016 Just picked up an STI DVC open gun in 38 Super and for some reason the hammer won't lock back after every shot even though it will most of the time when hand cycling it. Am shooting 38 Super Comp ammo at a PF of approx. 170 and still no luck. Breaks my heart. Any ideas ? Ever hear of this problem with the DVC ? Thanks in advance Link to comment Share on other sites More sharing options...
Mhall Posted November 6, 2016 Share Posted November 6, 2016 Is this a used gun? Sounds like hammer follow or trigger bounce. Does it double during live fire? Link to comment Share on other sites More sharing options...
zipollini Posted November 6, 2016 Author Share Posted November 6, 2016 New gun. Slide comes back during live fire, then returns and hammer follows slide forward. Can't shoot follow up shot as can't even get the hammer to manually lock back. Link to comment Share on other sites More sharing options...
JMike Posted November 6, 2016 Share Posted November 6, 2016 Hammer follow through. If it is new and un-molested, send it back to STI for repair. If you've been screwing around with it, take it to a gunsmith and sin no more! Good luck!Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Mhall Posted November 7, 2016 Share Posted November 7, 2016 Yep. Send it to STI. Link to comment Share on other sites More sharing options...
ar15rick Posted November 7, 2016 Share Posted November 7, 2016 (edited) Check the sear spring. It might be out of place or might have been adjusted to light. You will need to bend it for more pressure. Once the sear spring is good to go, also make sure to tighten the grip screws because that can make the sear spring get out of place.

10ring Posted November 7, 2016 Share Posted November 7, 2016 When I've had this happen I've been able to fix the problem by adjusting the Sear Spring finger that applies pressure to the Sear. It doesn't take much and it will be fixed. Link to comment Share on other sites More sharing options...

After I got up enough nerve to dissemble my new baby it turns out that the finger of the sear spring that rests on the sear had slid to the side and off the the sear. Once I realigned the sear spring and buttoned everything back up this seems to clear everything back up. Hope it lasts. Thanks for all the help and suggestion guys.

Powder Finger Posted November 7, 2016 Share Posted November 7, 2016 won't last you need to peen a spot below the finger part so it's wider and can't move to the left. Link to comment Share on other sites More sharing options...
