The M&P 45 Shield is built to last. Its polymer frame and metal slide can handle daily wear. The single-stack magazine holds 6 or 7 bullets. That may not seem like much compared to larger pistols. But the small size makes it easier to hide under clothing.

The Performance Center version improves performance. It has ports in the barrel and slides for less recoil. The action is finely tuned for smooth operation. The sights help you aim quickly with high visibility. An aggressive grip texture lets you hold tight, even with sweaty hands.

Numerous reviews and extensive data indicate that M&P Shield models are highly reliable. The .45 caliber variant is known for its higher recoil, yet it maintains excellent accuracy. It is also recognized as one of the most concealable .45 pistols available today, thanks to its slim design which facilitates discreet carry under clothing.

2. Sig Sauer P220 Legion

Pros:

• Top-Notch Trigger: Known for its excellent feel.
• Ready for Optics: Comes optics-ready for easy customization.
• Spot-On Accuracy: Hits the mark every time.

Cons:

• Limited Capacity: Holds only 8 rounds.
• Pricey: It's on the higher end of the budget scale.

Specifications:

• Caliber: .45 ACP
• Action: Semi-automatic, DA/SA or SAO
• Weight: 30.4 oz.
• Barrel Length: 4.4 inches
• Overall Length: 7.7 inches

• Low Profile Controls: Includes a decocker and slide release for smoother handling.
• Extended Beavertail and Undercut Trigger Guard: Improves grip and control.

We've always loved the original P220 but the Legion model takes it up a notch.

This striking pistol pairs a durable Cerakote Elite Legion Gray finish on the slide and frame with sleek black G10 grips. The modern styling looks as good as it shoots.

Beyond aesthetics, the P220 Legion's standout feature is the exceptional P-SAIT trigger. Its smooth take-up and clean, crisp break make it a joy to shoot. The short, tactile reset also impresses.

You can choose between two versions: A single action only (SAO) model with a thumb safety or a double action/single action (DA/SA) without manual safety. I'm partial to the DA/SA for its versatility—like a Swiss Army knife, it adeptly tackles any scenario.

The X-RAY tritium night sights illuminate low light shooting with ease. Ergonomic enhancements like the trigger undercut and extended beavertail promote an ultra-comfortable, controllable grip.

Though its 8+1 capacity isn't the highest, the P220 Legion's mid-size frame—7.7 inches long, 30.4 ounces—effectively tames the .45 ACP's stout recoil.

Meticulously constructed and reliably accurate, the P220 Legion has built a well-deserved reputation among discerning shooters. It delivers exceptional performance that's tough to match.

Pros:

• Softer Shooting: Significantly reduces recoil, making it easier to handle.
• Compact and Ergonomic: Enhanced grip and smaller frame improve handling.

• Optic Ready: DeltaPoint Pro footprint for easy optics mounting.
• X-ray 3-dot Night Sights: Enhanced visibility in low light conditions.
• Compensator: Integrated into the slide to reduce muzzle flip.
• Flat Trigger: Provides a clean pull and crisp release.

The Sig Sauer P320 XTen Comp pistol builds on the success of the original XTen model with two key upgrades - a compensator to tame recoil and a more compact size for easy carrying.

Its innovative compensator significantly reduces the stout 10mm cartridge's kick, making it very controllable for accurate shooting. The smaller frame retains an impressive 15+1 round capacity for quick follow-up shots, appealing to new and seasoned shooters alike.

However, the wider slide needed to fit the compensator does limit some popular customizations like the GoGun gas pedal takedown lever. While this may disappoint customization fans, it's a small tradeoff for the XTen Comp's overall performance.

Despite this minor limitation, the P320 XTen Comp shines thanks to its smart engineering, ergonomic design and flexibility. It stands apart in the market as a reliable, precise and packable 10mm pistol solution. The Comp model masterfully harnesses the power of the 10mm in a more shootable package.
