Title: P365 FrankenSig
Post by: Vinny on April 15, 2020, 02:33:18 PM: Besides raising the bar forever in terms of high capacity in a micro-9 size....I have to say I've really been enjoying the SIG P365's flexibility.
The shorter SIG P-365 and longer P-365XL Optic-ready slide can be used on either frame. You can come up with some interesting combinations. FrankenSig! O0

Thought I'd share these images of an SAS Slide with the new FT Bullseye Fiber-tritium sights that I purchased separately from SIG parts on the XL frame. This slide does NOT have the cutouts and can be used with the standard 365 barrel and spring set (also available through SIG parts). 12+1 9mm in this micro size is amazing!

Also pictured is the XL slide with the new Romeo Zero RDS.

Although the P365 (now with >4000) rounds has been 100% reliable with any type of ammo; I was reluctant to pocket-carry until I discovered these excellent Kydex Pocket holsters offered by Vedder or Alabama Holster that completely cover the trigger guards and have a thumb tab to assist release and easy draw.

For 10 round limited States of course the regular 10+1 frame will take 10 round mags (or 12 or even the 15 round mags where legal) but the XL won't take the short 10 rounders.

Meanwhile.....I just sent my standard P365 slide to Fabricated Arms to mill for a new Holosun 407K micro red dot. The Romeo Zero is OK, but I think the Holosun mounted on the short slide using the X-Ray 3 sights as my BUIS will be even better. 8) -Vinny

P365SAS slide on P365XL frame would be a great addition to P365 family.
I love SIG's flat trigger.

4100 so far on original X-Ray-3 slide (which just went for milling and patina cerakote). The SAS slide with the flat FT sights is brand new. This is a special slide available through SIG Parts (under slides) that is made without the slide cuts for ported barrel; so the standard barrel/recoil assembly from a regular P365 can be used.
Our range is currently closed so I've only been able to practice draw/present/and dry fire with the new slide. Really though, it's the same two-eyes-open on target presentation as a RDS for fast defensive shooting, not bulls-eye accuracy though.
Anyhow, I agree the XL's flat trigger and full grip is nice!

Post by: viking499 on April 15, 2020, 04:52:07 PM: Those look nice.

Can the 365 trigger work on the XL? I tried a friend's XL and never could warm up to the flat trigger.

I haven't tried it, but there's plenty of posts on SIGTALK showing it's a simple swap and the curved trigger parts are available for ~$40. Someone would probably be happy to buy your flat trigger parts too. ;D

The SIG P365 has become the #1 selling micro 9 pistol, so I believe there will plenty of parts and aftermarket support. I love that it takes about 10 seceonds to swap slides/frames. Awesome design.

I still love my Compact and full size CZ's but nothing CZ makes (yet) or anyone else IMHO comes close to filling the P365 category (I have a Hellcat, it's pretty good but I personally prefer the SIG's accuracy and flexibility). JMO YMMV

Yes, I will update post with pictures as soon as 407K arrives.
Been on order with Optics Planet since early Feb but like everything else..... ::)

At least Fabricated Arms has recently gotten the exact milling specs for the mounting lugs directly from Holosun, so I should receive the milled slide shortly.

G43 is a great micro; but has 66% less capacity. Maybe a 43X is for you.
But if you haven't already seen this extensive P365 article written by a G43 guy:

Post by: oldfrank on April 18, 2020, 01:32:42 PM: I love my 365 and it is my most carried firearm but I never felt like I had enough grip on it.

When I saw the XL grip frame on sale for $34 as Osage Country I oprdered and installed it. I like it even better and do not feel like it affected concealability at all.

Thanks oldfrank, great suggestion.
I prefer the Short Slide on XL Frame too. If you're gonna add the pinkie extension on the 10 round mags, might as well have 12 (of course where legal) The 12 round mags extend the short grip, but the XL frame just feels better.

The current model from Osage apparently comes with the mag release button pre-installed; but $39 still seems like a good deal:
https://osagecountyguns.com/sig-sauer-kit-365xl-grip-mod-blk.html

I guess you need the XL base pad if you're using original 12 round extension?

How hard is it to switch over the trigger parts, etc from the short receiver? Any tricks??
Title: Re: P365 FrankenSig
Post by: Vinny on April 20, 2020, 10:29:38 AM: Considering all the unrestricted interchangeable parts that can be shipped without an FFL; the P365 design is very flexible.
*Two grip frames: short 10 and XL
*Three Slides: one with X-Ray-3 sights, SAS with flush mount FT fiber-tritium, and XL with optic-ready
*Two Triggers: Curved or Flat
*Three Mag sizes 10, 12 or 15 round with flat base or pinkie base

Only restricted part that requires an FFL is the drop-in FCU that has the serial number.

The only thing I could hope for personally is an Optic-ready Short Slide with the optic cut in front of the X-Ray 3 rear sight to use them as lower 1/3 BUIS. Really, the optic negates any advantage of the longer slide's sight radius; and it would be a more concealable package.

Oh Well....That's the combo that Fabricated Arms is milling for me right now. O0

Are you keeping the rear sight? I was planning on having my red dot cut as far back as possible and eliminating the rear sight dove tail. With the Holosun 407K there is a built in rear sight anyway.

Togmaster,
I'm having it cut in front of the rear sight and keeping the X-Ray-3 tritium rear in place. Hopefully, the Holosun will sit low enough that the existing sights will lower 1/3 co-witness. I dunno, but I'm keeping my fingers crossed. That's how my SIG P229 RX and FN FNX-45 are set up and I like it.

If not, I can always use different height sights or just remove the rear and use the Holosun's 'sight notch'.

I've trained myself to be target focused and presenting the dot never look at those irons anyhow; just there in case the dot goes dark which rarely if ever happens.

I'd say you are correct. Especially considering the 100's of thousands they're selling; with social media if there were still any issues to speak of, you'd still be hearing about it big time. What little I hear involves early 2018 pistols.
From my own experience, I have >4100 rounds through my first one purchased in April 2018. It initially had to go back to SIG for one of the early issues but SIG corrected promptly and since then (2 years ago) it's been flawless and feeds everything. I've since added an XL and that's been 100% too. Even the excessive primer swipe that some were concerned about is gone, as SIG modified the striker slightly. IMO You're good to go. It's a great little pistol.

Togmaster,
I got the slide back from Fabricated Arms with the NEW cut that will accept any of the micro dots: SIG Romeo Zero, HS 407K/507K, Shield RMSc. The slide had some nicks and scuffs from 2 years use so I had them do a Patina Cerakote while it was there. Now.....just waiting on the HS 407K I ordered early Feb that just got pushed out again to early June. Meanwhile, with the irons in place for my BUIS I can still shoot it.

I carry both the PCR and P365 based on clothing. The P365 is much easier to conceal under a simple loose T-shirt in summer. In colder weather and heavier clothes it's the PCR for sure.

EM,
That's a really nice pocket carry set-up. I haven't really warmed up to the SAS Meprolight FT Bulls-eye sights; it's basically a point-shoot for me.
But the very compact SIG laser tucks into that pocket holster nicely.

Have you decided which setup you prefer.
SAS with laser, or X-Ray-3 sights with the TLR-6 ??
Title: Re: P365 FrankenSig
Post by: em44052 on May 15, 2020, 11:02:23 PM: Vinny, the sas and xl serve two different functions. I pocket carry the sas and found the laser help my older eyes to aquire the target quicker. I am not worried about snagging my pocket on the xl, so the x ray sights work well with the light and laser. The sas sights take time to get used to, and are not good for long range 10 yards max. I would say I prefer the x ray sights over the sas sights given the choice, but I do like the low profile of the sas for pocket carry.
Title: Re: P365 FrankenSig
Post by: Birdy on May 23, 2020, 12:07:56 PM: Here's my Sig P365X, that's a P365 with a P365XL lower. Works like a champ all of about 5 minutes to change over. Biggest problem I had was finding the Mag base plates to fit, had to buy from Sig, to use my 12 mags that I had. I wanted to keep it as small as I could for CC but had a hard time getting a good grip on the stock lower. Much better now. Less than $100.00 for it all including the three 12 round mags

Post by: Vinny on May 23, 2020, 03:22:33 PM: Yes, I think the XL grip with short slide gives a very compact and concealable 12+1 package!

I also found these 10 round mag extensions from Tactical Development that allowed me to convert my 10 round mags to fit the XL grip module for Range use.
Thankfully I don't live in a 'limited' State, but I figured for $13.99 each it was better than spending >$40 for extra mags.

EM,
That's a very intriguing setup for pocket carry.
All my sidearms have red dots which I really like for my 'ol eyes, including my RAMI with an RMR. But the RAMI is just too chunky to pocket IMO.

But for me the P365 is what I chose for Pocket Carry, which in Florida is pretty much year round.
I'm going to experiment with pocket-carrying a standard P365 with micro red-dot; and there may be some pocket holsters that have a built-in shroud. I have a Vedder Pocket Locker I really like, and Vedder's factory is in my town so I may drop by and see what they can come up with.

The SAS Fiber/Tritium bulls-eye sights are just OK up to 7-10 yards.
But your combination with the laser adds another dimension especially in low light where the FT sights are especially weak.

Might be worth a try. Lima365 or Crimson Trace??
Title: Re: P365 FrankenSig
Post by: em44052 on May 30, 2020, 09:05:47 AM: Hi Vinny, I used a Lima green laser for the exact reasons you mentioned. My eyes are not as good as they used to be, and I wanted be more accurate with my shots. The bullseye sights are also difficult to see in low light as you stated. Normally regular sights do not catch on anything, but I noticed with pocket carry, my sig sights were catching on my pocket at times when I practiced my draw. I like the SAS slide because of the snag free aspect, but added the laser to increase my sight acquisition time and better accuracy.
Title: Re: P365 FrankenSig
Post by: Vinny on May 30, 2020, 06:27:20 PM: Thanks EM,
I think you're onto a good combo.

I sold a pistol last week and had some change in my pocket.
So, I ordered a SIG Lima365 Thursday and had it today. Went together in no time and looks like it's factory molded as one piece with the receiver.

I'm looking forward to trying it at the range Monday. The manual says the laser dot should appear just barely on top of the front sight as you would normally present the pistol with irons. (If I understand correctly). So even if my 'ol eyes can't see the irons I'll see the laser dot. Like my Red Dots really.

However, as some others have commented the Lima365 grip button doesn't always positively engage even with my strong grip. Just the shape of my finger I guess. I added a double thick piece of electrical tape (another tip from another post) and it's better. Any other suggestions?

Before I order holsters, I may also try the Crimson Trace LG-422 which I've heard has a better grip button.

It's worth it to me to come up with a reliable pocket-carry combo that works best for me.
Thanks again for the suggestions! -Vinny

Vinny, I have seen post of other people having the same issue. I have not seen that issue with my Lima laser, but I have fairly skinny fingers. This may be an issue with people that have larger hands.
