Does the P320 Nitron have the same rusting issues that my P250s do?
I have two (2) P250 complete guns and a full-size "Conversion Kit" that are of the same construction and finish as the P320. I noticed that the slide releases and the leading edge of the rear sights have a tendency to rust! The rusting is where the gun presses against my synthetic holsters. The rust is very fine and powdery. The worst problem is that I was surprised to find that I had the same type of rust in the chamber of my EDC Compact model. It was rusted enough to cause the slide to bind up when I went to unload the gun for routine cleaning. Only the chamber was affected. The round that was in it had a premium nickel-plated case and copper-clad HP bullet and the case had rust on it, but it wasn't corroded itself. In all of the rust locations, the nature of the corrosion was where something contacted it. In the Tool and Dies Making business, we call that stress corrosion. None of these guns has ever been in a leather holster, so chemical reactions could be ruled out and I don't live anywhere near salt water. I take the same care of these guns as I do with my other guns and I have never encountered this with any of them, including blued-steel guns. Has anyone else had this experience?

Love this gun
Got this gun last September, great shooting gun. Very accurate I bought the small grip module because my hands are small fits like they custom measured my hand for it.

Simple, Safe, Reliable, and a great option for CCW
If your searching for a comfortable pistol for CCW look no further. One of the best features I have been playing with is the fire control group. You can just swap out grip modules it's a great perk!

Awesome handgun
I did quite a bit of research before I made a decision on a carry concealed handgun and from all my research and the pricing and the quality in the options this was the best handgun. I went ahead and ordered it and picked it up, a week later I took it to the range and it shot so easy out of the box barely any recoil and extremely accurate it is my favorite gun to carry with me at all times, I got the 40 calibre And I feel it is plenty protection for any time I need and I love the night sights that I can see anytime.. Definitely the best gun on the market for the money I would recommend it to anyone who is looking for a carry concealed or range handgun...

Perfect 45
I recently purchased my P320 .45 and could not be happier. This handgun performs perfectly, I was blown away with how smooth the mechanisms are. If you are looking for a quality compact this is it.

You will not regret it!
What a great weapon! With almost 1000 rounds fired without so much of a hiccup I wouldn't hesitate to purchase it all over again or recommend it to anyone. My only wish would be to have a slide that would except a red dot sight without having to replace it.

Sig Sauer P320 Compact
First time buying a Sig. I heard great things about it...absolutely true! Very light in my hands, shoots as straight as I can get it. Love the modular system so future opportunities are endless! I highly recommend this pistol.

Best compact polymer handgun
As of January 27, 2019 I have put 3,575 practice rounds ranging from MagTech, Federal to Remington and I haven't experienced a single malfunction yet. This includes 115, 124 and 147 grain ammo, all of it ran very smooth.

The slightly higher bore-axis gives it a slightly different recoil impulse than a Glock or CZ but is still completely manageable and easy to shoot. With a modern thumbs forward grip any additional muzzle flip is negated by your grip, however if you're right handed with long thumbs the takedown bar on the left side of the gun may be uncomfortable.

The slide finish is holding up near perfect even with this being my primary concealed carry firearm, I'm carrying in a kydex iwb holster which chews up the ndlc finish on my gen 5 g19 but my Sig P320 Compact is still looking good. There is some internal slide wearing but nothing which isn't expected at this round count.

The only con I can really think of is the cost of additional magazines but the quality of said magazines in my opinion makes.up for the price.

All in all this is a great firearm for home defense, concealed carry or if you're just looking for a range gun. Women may have difficulties concealing this firearm but only due to the normal fit of women's clothing, women who tend to wear looser tops would likely find it easy when carrying appendix.

I personally own two, one standard and one RX model.
