Have they worked out all of the issues with the new P365?
I don't own one, but my impression is no. Some of the early issues which included failures to extract and barrel peening seem to have been rectified by a redesign of the recoil spring assembly. The original pistols shipped with night sights that moved or fell off completely. SIG now installs their X Ray sights on the P365s which seems to have taken care of that particular issue.
On another forum, a new P365 owner was experiencing a 1-2% incidence of failures to extract, so that bug might not yet have been fixed. The two biggest concerns have been broken strikers and trigger bar springs that come unseated, resulting in a dead trigger. Both of these failures take the pistol down immediately and no remedial action is available. They have occurred after round counts running in the multiple hundreds, and they occur without prior warning. Not too good that, for a pistol clearly designed for self-defense and EDC.
SIG finally owned up to the fact that a large batch of pistols produced from early February of this year through April had strikers that may have been substandard predisposing them to fail. Most of the broken strikers had build dates in that period, but I have heard of one pistol with a May 2018 build date that suffered a broken striker. Many P365 owners have noted evidence of rather severe striker swipe on the primers of their ejected cases, and this may contribute to the strikers breaking off at the tip. Quite a few P365 owners have spent $100 on a tool steel aftermarket striker for their P365s in the interest of reliability. Personally, I am not convinced that the broken striker issue has been laid to rest. Unless you are willing to shell out a C note for a new part that does not enhance the function of the pistol in any way, only ensures the reliability of the striker.
As for the dead trigger/dislodged trigger bar spring issue, I am pretty sure that this dragon has not been slain. On another forum, one P365 owner had his trigger go dead, returned the pistol to SIG for repair, and had it go dead again within 200 rounds, and this was a recent occurrence.
In my opinion, SIG should recall all pistols with build dates from Feb through April of this year and replace the strikers, and they need to redesign the trigger bar spring.
