I cannot retract the slide far enough to engage slide lock and trip take down lever. Now what?
Welcome. . . . though not a good way to arrive at SigTalk if other options were available!
Others, who know more will be right along. The most likely answer you'll get is to call SIG and send the gun in. This may well be the best approach.
I've heard of similar occurrences with other guns, not the P365, but this may work. The idea is to reach into the guide rod hole and grab the spring - then pull it out of the guide rod hole.
Note though, the spring is strong, you would need an even stronger hook, perhaps 3/32" spring steel (you can heat bend the spring steel rod tight enough and it would not need re-tempering as the hook will be strong enough. Use the hook to capture a turn of the recoil spring as near to the muzzle end as possible, then pull the spring out the hole. In the process, the recoil spring would be destroyed. Since the recoil spring steel is harder than the stainless steel slide, there will be some scratches within the guide rod hole. Those can be easily dressed out.
Thanks for the reply Depalmi, the barrel will not seat on the take down lever because it is captured between the front of slide and the take down lever. The slide will not retract far enough to engage the slide lock.
1) Muzzle face of slide is is aprox 1/4 " in front of rear face of grip module, it is not as if in normal state.
2) Tip of barrle is 1" in front of outside face of slide.
I will post picture asap.
