Sorry it took a little while to get around to writing this up like I promised.

You guys talked me into it... So you are responsible!

Sig P365 produced April of 2019
200 Rounds of Federal American Eagle 115 FMJ
(1) Sig OEM 10-Round Flush Base Plate Mag
(1) Sig OEM 10-Round Extended Base Plate Mag
(1) Sig Accessory 12-Round Extended Mag
Cleaner - Birchwood Casey Gun Scrubber
Oil - Pro Shot 1 Step CLP
Lubricated per Sig Instructions

Accuracy (I'm not a great shot!) -
Rapid Aimed Fire At 7 yards. I
could generally put 9 out of 11 Shots or 10 out 13 within the 2.75" Bull. The others were generally called fliers. Either touched off high before the pistol returned to aim point or pulled low left. It's hard for me to keep my focus for that amount of rounds.

Reliability - I had an initial mag issue. The flush baseplate mag was binding up so bad on the first 5 rounds into the mag it was pushing the mag our of a Caldwell Loader instead of loading the round. On firing the first 6 rounds fired fine and the last 5 (the same ones the bound going in) failed to return fully to battery. I can only speculate that because of the binding those rounds where not positioned correctly in the magazine and where slowing the slide velocity. It only occurred on that magazine and only on the first 5 rounds loaded into it on the first cycle of the mag. It never bound up like that again and it never had a failure to return to battery again. It didn't have a malfunction in the next 189 rounds with any of the 3 magazines.

Shooting Comfort - It's unbelievably nice to shoot. By comparison although it's smaller in most dimensions than a Ruger LC9S/EC9S, only slightly wider and almost the same weight, with the same ammo it feels like the P365 is a 9mm and the Ruger is a .40. I did ride the slide lock a time or too but it's much farther forward (easier to avoid) and failure mode is to not lock open on the last round instead of multiple slide locks like a Ruger. I do believe most guys with large hands can adapt to it (Forget the Ruger). My hand size is large enough I ended up with my pinky tucked under the Extended 10 Round Magazine (The flush is a 1.5 finger grip for me). I can get a half pinky on the 12 Round.

So far Im pretty happy with it. Even if the problem with the flush pate magazine reoccurs, all I have to do is get Sig to send me a new mag. That's a very easy fix in this world.

PS Like I said your responsibile! Where do I send the ammo bill! It's to much fun to shoot! I would have shot more than 200 rounds but I needed to put 200 rounds of .45 ACP down range out of a 28 oz Pistol so didn't want to fatigue my grip.
 
I bought the P365 to replace my PF9 which was strictly a pocket gun. It is not only over all smaller except for the grip which is less than an 1/8" thicker, it carries 3 more rounds in the mag, shoots softer, (it compares well with S&W's Shield). I've put about 350 rounds through it with no problems, using a 'combat hold' and shooting slow, it shoots right to POA. When I speed up my shots, it starts shooting low, can't quite figure out why, might be time for different sights. They are quite bright in no/low light situations, not that good in day light, (has nothing to do with 65 year old eyes!). Because of the extra capacity, I'm rethinking it's role as strictly a pocket gun, maybe a Milt Sparks Summer Special 2. Toying with the idea of appendix carry, not sure if I want to go that way though. If I do, maybe a less expensive kydex holster and give it a try, Vedder Light Tuck, Panther Concealment, etc.
 
Mine came in last week. I was waiting on a deal with the 12 round mag included. I've put about 100 rounds through it so far. It's a great little gun. My pocket pistol for the last four years has been a P938. I intend to replace it with p365. No failures of any kind. As others have said the 12 round magazine is a bear to load first. It does get better though. The long steel rail insert in the plastic frame is a nice feature.
I have large hands but have not had any trouble as others have with riding the slide lock. The trigger was a little gritty at first. Some dry firing and a little dab of moly lube have taken care of most of that.
Shoots like a larger gun and extra rounds with a slim grip are great features. I was switching off between it and my 229 .40 easily.
I was comparing it with the P 11 I have and dimensionally they are very close. It's like everything wrong with the Keltec was addressed with the Sig.
 
I never did figure out what was going on with that first mag with the first five rounds. I pushed it down with a bullet nose to break the follower loose and put it back in the loader multiple times but after the issues loading and feeding those five it never reoccurred

In retrospect it may have been operator induced. If I had disassembled the mags, cleaned them and wiped the followers with a silicone rag I suspect it would never have happened.

The owner's manual does give instructions for disassembling and lubricating mags.

While I have always cleaned and relubed new guns, I have never done this with mags. Only after they accumulate fouling have I disassembled mags, cleaned and wiped springs and followers with a silicone rag. Other than that I've always run mags dry.
 
I usually run my mags dry also. My followers were rough and needed a little smoothing. A little use would have smoothed them out.
 
Receive my New Kahr last month. Bought 4 additional magazines. And as I always do. I load them to full capacity and let the Spring take a "set" for 48 hrs. And rack the slide and let the recoil spring take a "Set". Gun ran flawlessly, just like all my guns do when new. Just ordered 4 more and now doing the same. When I first start shooting my guns, I never load them to full capacity at the beginning. Just let them wear in a little.
I do not take my magazines apart. I just put them in my Sonic Cleaner with Ballistol Milk. Cleans them great and leaves a very fine coating of lubricant on them. Then spray out the excess with a can of dry air. All I know is, it works for me. .

I too, replaced my P938 with the P365 and have not looked back. It's been 100% reliable. No issues; none, nada, zero, zip. The P938 was great and served me well for over 3 years, but the P365 surpasses it, IMO. Higher capacity and more simple manual of arms and still fits in my pocket...what's not to like?

Gee thanks. Now you are trying to get me to jump ship I see!!! I have the P938 and love it, but the extra capacity is enticing... Dang all of you!!! :fire: ;)

I am a little confused by your description. What do you mean multiple slide locks on the Ruger? So you did ride the slide a couple of times, but failure is not to lock open on the last round? Does that mean you were riding the slide but not enough to make the gun fail except on last round? I find this interesting since yesterday I took my LC9S out for a range day. I do not carry the Ruger any longer, but have moved on to other Micro 9mm's. I have to say the Ruger performed flawlessly like it always does and is quite accurate. Had no problem shooting fast head shots at 10 yds with most shots going into a 3-4" group. I have never had a failures like you describe. and I have a size large hand. The only reason I do not carry the gun any longer is because I feel the Trigger is too light for my taste. Still a very nice gun.

I did shoot the 365 and yes it is a very nice Micro 9mm. Shot fine, but I felt the gun shot very similar to the Ruger LC9s. A little snappy, but with a slightly less recoil and muzzle flip than the Ruger. To me, it sure did not make the LC9 feel like a 40.cal. Personally I found the 365 and the Ruger to share many of the same similarities. Thin design, weight etc.
And comparing the 365 to the LC9s certainly is not meant to disparage the 365. On the contrary. I do prefer the Ruger over the 365 simply because of more room for two handed shooting. The 365 having the ability to carry a few more rounds.
I also have a feeling the lessor amount of recoil or muzzle flip may be because the 365 is heavier on the top end, which is a good thing IMO.

Regardless, I am very happy you are enjoying your 365. I think you have found a winner. Congratulations!

Ps If you have a scale, I would really like to see the weight of the 365 receiver and barrel. I already have the weights for the Ruger. I keep notes on these kind of things and would appreciate it. thanks.

With my hand size I find it difficult to grip the Ruger LC9S or EC9S (Own) in such a way that I don't either inadvertently activate the slide lock (locking the slide back with rounds in the gun) multiple times or have the gun squirm in my grip to the point it affects accuracy. If the slide lock had been scaled up from the LCP this would not have happened. It's not flush enough. While gun mods and/or training can help alleviate the issue I'm not confident in a high stress situation I wouldn't lock the slide back after 2 rounds.

With the P365 the slide lock is positioned farther forward (making it easier to avoid) and flush enough that if you ride it the failure mode is to not lock open when empty.

Given a choice of the to failure modes I prefer the P365. If it occurred in a high stress situation it's likely to be less catastrophic. After all I have pistols (LCP for instance) that are not designed to lock back on an empty mag at all.

I just prefer failure to lock back after 11 rounds on an empty mag to locked back after 2 with 9 still in gun.

Having both the advantages to the EC9S are price, thinness and if push comes to shove I may like the trigger slightly more. The thinness is a double edged sword as it reduces shooting comfort and causes grip issues (for me). It's the reason I shoot a .45 Shield better than 9mm even though flush or extended mag in the 9mm makes no appreciable difference in my scores.

I was trying to address an issue many with large hands have with the lack of real estate available on smaller guns.

This may or may not be an issue for you.

PS What I would really like is a flush slide lock positioned like a 1911 on all pistols but it isn't likely to happen.
 
I have never heard the Ruger LC9s ever to have that issue in all the years I have owned one. To include the original model when it first came out. But if you say you had issues, I will take your word for it. I would say to send it back to Ruger, because you should not be having these problems.

It's not really a malfunction. I am activating the slide lock. The slide lock is doing exactly as it was designed. I either have to use a revolver grip (allows the pistol to squirm) or my usual pinch grip with a splayed thumb. Under stress such as timed drills I allow my thumb to migrate back in which then nudges the slide stop on recoil and locks the slide back. I could train that out eventually put under extreme stress I might relapse. This is a fairly common issue with big hands and small guns.

This isn ot a problem on an LCP because the stop is completely flush and very stiff. As a matter of fact I can not use the slide stop at all on a LCP with a normal grip (My thumb won't come back that far). To "make safe" at the range I turn 90 degrees from the course of fire, hold the pistol from the base of the grip from the back with my right hand while its on it's side (while pointing down range), overhand rack with the left hand and push the slide lock up from the bottom with my thumb. If you have ever watched Hickok45 on YouTube you may have seen him do the same with small guns.

To give some idea of my hand size I have short fingers for my hand size but I have to be careful to keep my left thumb out from I'm front of the muzzle with an LCP. On a G19-4 my middle finger is directly centered othe ridge that is supposed to be between the middle and ring finger. On the P365 10-Round Mag WITH EXTENSION I can get 2 Fingers on it.
 
I was wondering the Ruger lc9s and the sig 365 looks very close to the same size do anyone know if the Sig will fit most holsters for the Lc9s? I'm wondering because i carry a Lc9 now and have a few holsters for it and been thinking about getting an lc9s in order to use the same holsters but I do like the sig.
 
My experience with the P365 has been nothing but positive so far. It's seen circa 1200 rounds as this point. Not a single hickup or bobble of any kind yet. I must say I'm anticipating a light primer strike or broken striker at every magazine... but nothing yet. I'm working on it, but I expected something by now according to some reports. So far, incredibly pleasant, accurate and 100% reliable with 124gr HST +P and reloads I try to replicate this round.

Maybe I can encounter a malfunction in the next 1k rounds. From my current experience, I don't feel comfortable betting on a malfunction.
I'm very impressed at this point.

Sig is about 0.125 thicker. Kydex not likely. Leather... Maybe.

I concur. I can't believe how fun this gun is to shoot. 124g hornady hp over 5.2 unique. 1080 fps. Equals hornady factory load in velocity. Very little muzzle flip for a small pistol.
