Key Features

• Optics Ready Slide (OSP) – You can mount a red dot directly to the slide without extra plates. That means faster target acquisition and less hassle for new shooters.
• 4″ Hammer-Forged Barrel – The barrel is made from hammer-forged steel, which gives you better accuracy and longer barrel life than cheaper button-rifled barrels.
• Melonite Finish – The slide gets a tough Melonite treatment that resists rust and wear. It’s the same finish used on many duty guns, so it holds up to daily carry.
• 10-Round Magazine – Comes with a flush-fit 10-round mag, perfect for states with capacity limits. It also gives you a comfortable grip for smaller hands.
• Loaded Chamber Indicator – A small tab pops up on top of the slide when a round is chambered. It’s a simple visual cue that helps you stay safe, especially if you’re new to semi-autos.

Who It’s For

This pistol is a great fit for first-time gun owners who want a reliable home defense or range gun without spending a ton. It’s also a solid choice for experienced shooters who need a backup or a beater gun for classes. The 9mm caliber and 10-round capacity make it easy to shoot and easy to find ammo.

Pros & Cons

• Pro: Optics ready at this price point is rare – most guns with an OSP slide cost $100 more.
• Pro: The trigger has a short reset, which helps you shoot faster on follow-up shots.
• Pro: The grip texture is aggressive enough to keep the gun secure, even with sweaty hands.
• Con: The magazine release is a bit stiff when new – it loosens up after a few range sessions, but you’ll want to practice reloads.

Comparison

Feature	SPG XD MOD4 OSP	Zev Technologies OZ9	Lone Wolf Distributors DLC-9
Price	$369	$1,200+	$550
Slide Finish	Melonite	DLC	Nitride
Optics Ready	Yes (direct mount)	Yes (plate system)	Yes (plate system)
Barrel Length	4″	4.5″	4.1″
Mag Capacity	10 rounds	15 rounds	10 rounds

The Zev is a race gun with a premium price – it’s for competition shooters. The Lone Wolf is a solid mid-range option, but it’s $180 more and still uses a plate system for optics. The SPG gives you the same core features for a lot less cash.

FAQ

Does the SPG XD MOD4 OSP come with a red dot sight?

No, the slide is cut to accept a red dot, but the sight itself is not included. You can mount most popular micro dots like the Holosun 407K or Shield RMSc directly.

Is this gun safe for left-handed shooters?

Yes. The magazine release is reversible, and the slide stop is ambidextrous. You can swap the mag release to the right side with a simple tool.

Can I use +P ammo in this pistol?

Yes, the XD MOD4 is rated for +P ammunition. Per Springfield Armory specs, the barrel and slide are built to handle higher pressures, but you’ll see more wear over time if you shoot +P regularly.

What holsters fit this model?

Most holsters made for the Springfield XD 4″ service model will work. The OSP slide is slightly taller than the standard model, so check that the holster is cut for optics.

How do I clean the Melonite finish?

Use a standard gun oil and a soft cloth. Avoid abrasive cleaners or steel wool – the Melonite is tough, but scratches can still happen.
