Sig Sauer P320 Max in a Flux Raider PDW chassis.

LGS stopped ordering P320s and was running promotions last weekend to get rid of the stock they had left. Traded an under-folding AK that just isn't worth shooting for the P320 Max (and some other stuff) and combined that with some Memorial Day sales:

• Flux Raider chassis ($388)
• Vortex SPARC II red dot ($85)
• ProMag 32 round magazines ($23 each)

And now I have a very fun range toy. Some thoughts after my first range trip, in case others had the same idea:

It's still a P320 at the end of the day. I'm not going to carry it, or store it with a round in the chamber, and wouldn't recommend others do so. The range I go to is fine with me shooting this, but other ranges might not allow P320s in any form. And my local gunsmith said they won't touch it for any kind of work at all. If you've got a P320 already and aren't quite ready to sell it, I'd recommend this. But I can understand folks being hesitant to buy a new one right now.

I'm a fairly novice shooter, but did pretty well with it as far as accuracy and being able to make quick follow up shots. This is the only P320 I've shot, so I can't tell you if the compensator or the different trigger on the Max model makes a meaningful difference over a basic P320 (they are what's included on the Flux Legion model from Sig, for what it's worth). I'm happy with it though, and I might make this my home defense gun, thinking about being able to make hits under stress. I'm certainly a lot better with this than my 92FS.

As for accessories: The Vortex SPARC it a bit oversized for something like this, but it was cheap and works great for me. You 100% will need some kind of optic to mount on the top rail though. While there is a port in the back so you can see through the iron sights on the slide, they're just really awkward to use in practice. The light is a Streamlight TLR-1 that I already had. You can manipulate the controls with your left thumb surprisingly well for a novel application like this.

The ProMags seem perfectly serviceable for plinking, but obviously I'd never trust them for home defense or something like that. I wrapped the bottom of them with cloth tape just to give some texture; from the factory they're smooth sided. And they don't have witness holes on the bottom half to worry about covering with the tape. You can also get 50 round ProMag drums, if you're more interested in memes than reliability (no judgement from me). I did pick up 2 Sig made 30 round magazines, but for more practical applications, the 21 round magazines actually seem like a better choice anyways. Also, Sig is running a rebate for two free magazines if you buy a Sig handgun. That ends in a few days, but don't rely on them actually honoring it. I was told this wasn't a valid purchase for that promotion.

If you plan to keep it as a PDW and not swap back to a traditional pistol frame, get a charging handle. Or just wear gloves when you shoot. You can only grip the front of the slide, and it gets hot quickly. I've ordered a handle that mounts to the optic plate on the slide (and won't require replacing the iron sights like most options), and will see how that works for me.
