You have to keep in mind the 365 was designed as a carry weapon. That being said, I put one of the smallest cans on the market on mine and it essentially turned it into a single shot pistol. I used a jk 105 ccx 9 with a threaded faxon barrel. The jk 105 is a direct thread(no piston) 9mm can. I’ve been meaning to try some different springs, but other projects have moved it lower on the priority list. Hopefully, someone here has been able to get one to work well and will comment.

 

Thanks for your feedback!

 

I have no trouble using a can with my P365 hosts. My results are with a couple of P365XL/MACRO 3.7" slides using 4.35" threaded barrels; one is from True Precision, the other I fitted from Bar-Sto. The 9 mm can I use on both is the SIG Sauer MODX-9 in its full-length configuration and the standard "high rate" piston spring. I typically use Federal 147 gr subsonic rounds (Syntech for training and HST for EDC), but others have given similar results. It is important to clean the piston and piston housing every few hundred rounds to ensure smooth operation. I do not have any P365 barrels with an LCI (whether threaded or not) and would not want one, especially with a can. Suppressors run fairly dirty on a 9 mm host and an LCI notch would only make it worse on the RDS that I always run on these pistols.

If you find trouble running this can on a 3.1" P365 slide, you can (no pun intended there) a) try the "low rate" piston spring, and/or b) reduce the number of baffles used. The same advice goes or any such modular suppressor.

Good luck!

 

I had no issues running my XL with my TBAC FLY9 can, short or long version, with subs and supers.

The standard length 365 will not run for me with subs no matter what I try. With supers it'll run with the can short or long and whatever spring I want on the Neilson device.

 

There's a boatload of YouTube videos showing what kind of experience people are having with suppressed P365s. This is one using the Dead Air Odessa 9 modular and it shows how it functions from minimum to maximum number of baffles.

 

My P365XL and X-Macro are mainly used for EDC; I don’t believe the model is intended for suppressed. If so, not really interested. If I play spies, my preferred one is the Beretta 80X Cheetah Tactical in .380 super suppressed 🤙🏻

I do use a Sig MODX-9 for my 9MM threaded barrels 😎
