P365 is this normal?

[Victor R.]

Went to the range and have an issue not sure I should be concern about. After the magazine was emptied the slide did not locked back, it happened a couple of times. I pulled the trigger and it did not fired then carefully, released the magazine and pulled back the slide to be sure I had nothing in chamber and I didn't. Is this normal? Because it happened only twice out of 5 or 6 loads. Now, after I cleaned the pistol the magazines are very tight to lock-in if they are full with ammo.
Please help and thank you

Doesn’t sound normal. Have you disassembled the mags?

 

[Victor R.]

No, I did not. I just cleaned the mags when I cleaned the gun, but nothing out of normal. To locked-in the mags now I have to push hard. at least 5 lbs. push

Define Cleaned the Mag? If you oiled the top of them, that is your issue. Strip, De-grease, lightly oil the spring. If this issue persist then give SIG a call. The tightness in the magazine should ease up if you leave the rounds in the magazine for a while. They are still tight at Max capacity.

Ammo grain 115?

 

[Victor R.]

I did clean the mags' top with the same cloth with CLP (break free) on it. And Yes I used 115 gr and 20 rounds of SIG V-Crown 124gr.
De-grease with anything specific?

I would say something about selling that junk and buying a Glock 26 or Shield, but I won't lol.

 

[RiverBend]

yup, Austrian trumps German,

No it is not normal. Does it do it with more than one mag? If not you probably have a mag issue. If it does, the gun needs to be looked at.

^^THIS^^ 100%. If it does it on all mags, it's a gun issue. Just the one mag, it's a mag issue. Either way, diagnose it and contact Sig. They'll make it right.
