Cameras Don't Lie: 9mm vs .45 ACP

August 05, 2020 By Guns & Ammo Staff

The age-old question, 9mm vs .45 ACP. For some, this has been asked and answered already. For others, the debate goes on. In this segment of “Cameras Don’t Lie,” competitive shooters Patrick Sweeney and Jim Tarr head to the range to put the vaunted loads on record, and then consider the footage.

Using nearly identical guns, both from the Remington family of polymer-frame, striker-fired RP pistols, loaded with Hornady ammunition, our shooters set out to compare often unseen measures such as muzzle rise and slide-lock time. Thanks to the aid of high-speed cameras, they can finally put to the argument to rest. Which round is better, 9mm or .45?

The Do-All Scattergun: Winchester SXP Pump-Action Shotgun

When considering American sporting long arms, the name Winchester looms large among both shotgun and bolt-action rifle offerings. The spiritual successor to the classic Winchester Model 12 pump-action shotgun, the SXP family is replete with features and offers exceptional value. Two configurations to note are the SXP High Grade Field and the SXP Waterfowl Hunter Camo. Both guns are available in 12 or 20 gauge with 26- or 28-inch barrels. The biggest difference is the stock material, Turkish walnut for the High Grade and camouflaged composite for the Waterfowl. Also, the Waterfowl Hunter can be had with a 3-1/2-inch chamber for heavier duck and goose loads. Fast to shoot and easy on the shoulder, the SXP continues Winchester's legacy of excellence afield.

High-Velocity Handgun: Smith & Wesson M&P 5.7

Beginning with revolvers and growing to include pistols, rifles and even a bullpup-style pump-action shotgun, Smith & Wesson's Military & Police (M&P) line has garnered a reputation for reliability in the hands of professional users and armed citizens, alike. Given its expansive catalog and a history that dates back to the mid-1800s, Smith & Wesson has been churning out a remarkable number of “firsts” in recent years. Add to that list its first 5.7x28mm firearm in the form of the M&P 5.7 pistol. The potential of the high-velocity cartridge is harnessed by S&W's brilliant Tempo barrel system, and the pistol offers an astounding 22-round capacity on top of standard features like the flat-face trigger and optic-ready slide. In form and function—including the new FDE finish—the M&P 5.7 continues the tradition of Smith & Wesson's military and police offerings, and ably expands the line to include the 5.7x28mm chambering.

The Original 5.7: FN Five-seveN MRD

Popularity of the 5.7x28mm cartridge has never been greater, and shooters today owe a tip of the cap to the ammunition's creator, FN. Despite being the only game in town for nearly two decades, FN was not content to rest on its laurels. Recently, the company set out to update its 5.7 handgun offering, and the result is the FN Five-seveN MRD semiautomatic pistol. Utilizing delayed-blowback operation and a single-action trigger, the MRD is both accurate and a joy to shoot. Too, compared to earlier offerings, the MRD comes with enhanced ergonomics and an optic-ready slide. For those wanting to experience the power and precision of the 5.7x28mm cartridge and desire a high-quality handgun from the ammunition's original maker, look no further than the FN Five-seveN MRD.

Best Ever Carry Gun? SIG Sauer P365 XMACRO

SIG Sauer turned the polymer-frame pistol market on its ear when it launched the slim, high-capacity P365 micro-compact pistol. What ensued was a race to develop the best carry pistol, period. And, while the micro-compact design was ideal for many users, some shooters desired a little larger grip and additional onboard capacity. Here, the modular P365 design excelled, and the XMacro configuration utilizes the same firing system, but wears a larger frame, slide and barrel. Boasting 17-round capacity, an optic-ready slide and a dustcover accessory rail, the compact XMacro offers full-size utility in a portable package.

Free Ammo! Walther PDP Special

Ultimately replacing the acclaimed PPQ family of semiautomatic pistols, Walther's PDP platform has become the brand's flagship handgun. Available in configurations for duty and defense, concealed carry and even competition, the PDP has been nothing short of a homerun for Walther and an exemplar of ergonomics and excellent triggers among its polymer-frame, striker-fire peers. Standing out in the lineup are the F-Series pistols. Available in 3.5- and 4-inch configurations, the F-Series PDPs were designed for shooters with smaller hands or reduced grip strength. In particular, Walther consulted with women in firearms industry, honing the F-Series to fit their needs. Changes included a reduced grip circumference, shorter trigger reach, and an easier-to-rack slide assembly made possible by an innovative two-piece striker system. The end result has been a hit with male and female shooters, alike. Now, qualified purchases of any PDP pistol will also include 100 rounds of ammunition to help buyers save money and shoot more.
