P320 FULL-SIZE

What’s the Best Way to Get a Full-Size Duty Pistol Without Breaking the Bank?

Imbertsmithersarms is a Grand Forks, ND-based retailer specializing in firearms and gear for hunters and outdoorsmen. The SIG Sauer P320 Full-Size is a modular striker-fired pistol that set a new standard for duty and home defense handguns. Its core innovation is a serialized, removable fire control unit that allows for easy caliber and size changes. In stock and ready to ship today for $443.75 (regularly $519.99).

Why This P320 Full-Size is a Smart Choice for Your Collection

I’ve seen a lot of handguns come through our shop, and the P320 platform changed the game for a reason. It’s not just another polymer pistol. That serialized fire control group—the actual “gun” part—is what makes it special. You can swap out the P320 full size grip module for a compact or carry size in minutes, no FFL required. Want to run a suppressor? Drop in a P320 full size threaded barrel. This modularity means your initial investment grows with you, which is a huge win for budget-conscious shooters. It’s the same proven system adopted by the U.S. military and countless law enforcement agencies, which speaks volumes about its reliability. For a hunter like me who spends more time thinking about opening day than anything else, having a dependable, versatile sidearm for the truck or the cabin is non-negotiable.

The Straight Talk: Pros & Cons

After handling hundreds of these, here’s my honest take.

Pros:

• ✅ Unbeatable Modularity: The FCU system is genius. Change your P320 full size frame or entire setup as your needs evolve.
• ✅ Proven Reliability: This isn’t a range toy; it’s a duty pistol with a track record you can trust.
• ✅ Excellent Ergonomics: The grip angle and texture work well for most hands, a key for all-day carry or training.
• ✅ Massive Aftermarket: From P320 full size holster options to triggers and sights, you can customize every part.
• ✅ Strong Resale Value: The SIG name and modularity hold value better than most.

Cons:

• ❌ Size for Concealed Carry: The full-size model is, well, full-size. It’s a great duty or home defense piece, but can be a challenge to conceal under a t-shirt. If deep concealment is your main goal, check out our P320 Compact models.
• ❌ Stock Trigger Feel: The trigger is consistent and safe, but some shooters find it a bit spongy compared to a tuned 1911. This is easily upgraded later if it bothers you.

Who Should (and Shouldn’t) Buy This P320

Buy it if: You’re a first-time handgun owner wanting a do-it-all platform that can grow. You’re a hunter or outdoorsman needing a reliable, full-capacity sidearm for property or backcountry. You’re interested in practical shooting sports like USPSA or IDPA in the Production division. You value the modularity to have one FCU that can serve as a nightstand gun and a winter carry piece with a simple grip module swap.

Skip it if: Your only goal is ultra-concealed, lightweight, everyday carry. (Look at the P365 series). You’re a collector seeking a classic, all-steel DA/SA pistol. You’re on an extremely tight budget and just need a basic .22 plinker. (We have other options for that).

Got Questions? Let’s Address Common Concerns

“Is the P320 still safe? I heard about the drop issues.” This is the most common question. Yes, it’s safe. The voluntary upgrade program from SIG Sauer years ago addressed the early drop-safety concern on certain models. Any P320 you buy new today, including this one, has the updated, tested design. It meets all current safety standards.

“Is the modularity complicated?” Not at all. Swapping the fire control unit into a new P320 full size grip module takes about 30 seconds and requires no gunsmithing. It’s designed for end-user simplicity.

Frequently Asked Questions

This P320 Full-Size represents a serious value at $443.75. You’re getting a battle-proven, modular platform that can adapt to almost any role you need it to fill. For the hunter, the homeowner, or the shooter looking to get into practical sports, it’s a tool that won’t let you down.
