The Sig Sauer P320 9MM Compact with contrast sights is a polymer-framed service pistol with an enhanced level of safety. The P320 compact has easy maintenance without requiring the operator to pull the trigger or use a special take-down tool. Slide and barrel conversions allow different caliber and barrel lengths, and the P320 compact is able to be personalized to any hand size due to its modular grip frame and removable fire control assembly.

The Sig Sauer P365 is near pocket pistol-sized and the P320 Compact is smaller than most duty pistols. The P320 Compact comes from the Glock 19 sized school of designing compact firearms.

Sig Sauer p320 Features

Safety

The Sig Sauer p320 Compact has the usual suspect of safety features including firing pin, trigger bar, and others that make the gun just as safe as other pistols in the Sig line.

What this pistol does have that no other striker-fired gun does is a single-piece trigger.

The trigger pack inside the gun is designed to have a one-piece trigger instead of the widespread two-piece hinged trigger of Glock and M&P design that houses a safety feature to control the striker.  The safeties of this gun are all truly passive and operate without input from the shooter.

This makes the trigger very smooth, consistent and can be had in either a standard, short-reach, or small bladed design.

Fire Control Unit & Caliber X-Change

One of the coolest features of this gun is what part constitutes the “gun.”

As far as the ATF is concerned the “gun” is the part that has the serial number on it.  That means everything else is just a part.

The slide, and more importantly, the grip frame, are not serialized.  You can shoot all the common calibers out of this weapon by just changing slides and mags.  You can also re-size the gun to your hand by having the entire grip changed, not just a few panels.

Sig calls them Caliber X-Change kits.

Sig offers kits to change sizes, Full Size, Compact, and Subcompact and caliber change kits for .380acp, 9mm, .40s&w, and .357 Sig.  The kits include the new slide, grip module, and proper magazine for the caliber and grip size.

This system works well. To convert a Glock 19 or Glock 43, for example, you choose from the calibers that your gun can fit and need a new barrel and a magazine. You can save several hundred dollars over buying a new weapon with this system.

Grip Frames

Sharing both grip frames and magazines with the P250. The Sig Sauer P320 compact has the ability to tailor the size of the gun and the circumference of the grip width, with just the change of the plastic grip frame.

The serialized part of the gun is the steel fire control unit mentioned above.  This means you can buy grip frames online and have them shipped to your house, no FFL required.

This is perfect for people who want different grip sizes or want a pro to stipple their grip since now you can just send the hunk of plastic through the regular mail.

Integrated Red Dot

Sig Sauer joins others with a cutout for a red dot sight available from the factory. The twist is that theirs comes with a red dot sight installed as well.  The “RX’ model comes with Sig’s own Romeo 1 red dot.

Sig Sauer p320 Compact Take Down

The takedown of this pistol is easy and can be done without pulling the trigger.  All you do is lock the slide back, rotate the takedown lever clockwise, and then slide off the upper half of the gun. It is easier to put the slide back on with an empty magazine inserted because it lifts the slide lock and makes it easier to move the slide rearward and rotate the takedown pin counterclockwise.

Accuracy & Reliability

The gun is accurate enough to be used in a competition and will easily outshoot most shooters.

The gun functions and fires all hollow points and plinking ammo you can feed through it into one ragged hole if you do your part.

However, there are a few things to note about the accuracy of this gun.

The trigger blade is large and deeply curved.  Until you get used to it the trigger can be a serious hindrance to accuracy.

The trigger pull is consistent with no stacking and seems to be within the 6-7 lbs that a striker-fired gun needs.

Stacking is where the trigger gets heavier as you pull it until it breaks, common on older pistol designs, especially double-action triggers.

Finally, the grip panels are good and the overall width of the grip can be tailored by ordering one of several different available plastic frames.

Sig Sauer p320 Compact Ergonomics

This gun feels very much like a Sig.

The high bore axis makes it feel a little like holding a ray gun but it is very comfortable in the hand.

The plastic frame feels warm even in cold weather and the grip panels feel almost like skateboard tape, but without the sand.  It’s a subdued stippling that works better than it looks.

Quality & Durability

The Sig Sauer P320 for sale is an entry-level Sig gun.  That doesn’t mean that it is low quality.

Sig Sauer makes by far the best polymer-framed guns in the world and by far some of the most accurate and dependable pistols.  You must accept the fact though…the grip frame is made to be almost disposable.

This is important because the plastic of the Sig Sauer p320 9mm isn’t as resilient as Glocks or M&Ps.

All the models offer Picatinny rails that are squared away under the barrel, in front of the trigger guard for mounting a light or laser.  The whole gun, finish included just seems more susceptible to dings, and scratches…more so than any other gun I’ve ever used.

Sig Sauer p320 Applications

The Sig Sauer P320 for sale is good for many things. But there are a few models that are better suited than others.

The RX Carry is probably the most capable of the bunch.  It comes with a red dot sight mounted on the slide. The factory included 21 rounds of magazines. Generally only useful for open carry or for competition/range use.

CALIBER AND CAPACITY

The Sig Sauer P320 Compact offers 9mm, 40 S&W, and 357 SIG as caliber options. The larger Sig Sauer P320 Compact predictably holds more rounds than the Sig Sauer P365, and more rounds are often better than fewer rounds, right? The P365 gets close with its 15 round extended magazine, but the Sig Sauer P320 for sale can carry up to 21 rounds.

Sig Sauer p320 Holsters

Nearly every custom Kydex maker has holsters for this gun so for concealed carry or for range use you should be fine.  Including holsters for weapon lights, red dot sights, and suppressor height sights.

RAILS AND ACCESSORIES

The Sig Sauer P320 Compact has an excellent Picatinny rail. That allows you to mount a light, laser, or training device to it. As fans of weapon-mounted lights, the rail definitely makes a difference.

Sights aside, there aren’t many parts available for the Sig Sauer P320 9mm yet.

Sig Sauer offers replacement spring kits and grip modules as well as the previously mentioned caliber X-change kits.  They offer a thin-bladed trigger that is available for purchase, it’s not an upgraded trigger, just a different blade.

The only “big” upgrade currently offered is the Apex Trigger kit available.

Sig Sauer is also offering a grip module that has a built-in laser.  It looks like an overgrown S&W Bodyguard .380 and is very expensive.  You also lose the ability to mount a light and need a custom holster.

Weapon Light

No defensive gun is complete without a good light mounted on it, for the Sig Sauer P320 for sale, (and most other guns) the Streamlight TLR-7 is an outstanding choice.

Delivering high lumens, great durability, and coming in at a decent price – it’s a must-have.
