365XL trigger help

[krvincen]

So I purchased a new P365XL recently with the Romeo zero on it. I have hit about the 509 round mark earlier today and still have issues with the trigger. Mostly it feels great but at least one pull per magazine or two it suddenly feels very gritty and spongy and seems like the break point is off. Has anyone else had this problem?

 

[BugI02]

Is there any pattern to the problem such as one particular magazine, one particular manufacturer of magazine or what position in the load out has been chambered (first round in a mag, last round etc)

 

[krvincen]

None that I have been able to notice. Some times it will go an entire mag without a problem sometimes a few times a mag. Tried different lubes, different loads, etc.

Haven't experienced anything like that with any of my 365's.

Seems odd it would be inconsistent.

I assume you haven't had any failures to fire, etc since you haven't mentioned it.

Nope, not one single hiccup with various factory lids and both different factory loads and two completely different reloads utterly reliable in that regard. Just trigger gets wonky every so often.

That is strange. Might pull out the FCU and give it a look (pretty easy to pull out the FCU) Not sure what to tell you to look for other than maybe some gunk/factory grease in the trigger mechanism.

Someone with more knowledge of how the trigger in the 365 is engineered may be able to tell you more.

Thanks I’ll take a look at it. It’s disappointing in an otherwise great handgun.

I'm not familiar with the P365XL, does it have a magazine disconnect?

I was trying to figure out something that could intermittently and randomly interfere with trigger action. One possibility that occurred was if the pistol had a magazine disconnect, it might not be accepting the magazine's notch/tab correctly, and this is altered by recoil such that the problem occurs after one recoil and the recoil from firing the round exhibiting the trigger interference clears the problem temporarily

This is pure speculation as I am not familiar with the internals of that FCU

 

[krvincen]

I’ll have to do some research as I’m not familiar with it much yet either. Been tearing Glocks all the way down since my first Gen1 G17 30 years ago but never really done much to any other pistol designs other than typical field strip and clean

No mag disconnects in the 365 series.

Thanks. I thought those were needless complexity and a bad idea that had gone away but I thought I remembered reading it was an option on the P320

Well I removed the trigger pack assembly and after wiping everything down put some X-F7 gun grease I use in my M1A on moving parts. Without some range time to really rest it I will say I cannot get it to repeat the problem dry firing and it seems much smoother now than before as well.

That’s weird that it wanted grease. Something’s funky!

Maybe the through cleaning did it. Grease is just a unneeded addition.

That's what I was thinking.

If you didn't do it already remove the striker and clean the factory oil off of it too. It is notorious for causing light primera strikes.
It happened to me then after researching I found I wasn't the only one.

Agreed. I had that issue. Cleaned off the striker and the channel and no more light strikes on mine.

Noted. Definitely removing mine. I haven’t had any light primer strikes but I’ve also only shot 100-ish rounds.

Does Sig use surface protectant or oil when they ship out? I know it’s easy to confuse protectant with oil.
