Glock vs. SIG Sauer: What Do Police Like Best?Glock handguns have been used by law enforcement for years, and more than sixty-five percent of U.S. police departments use Austrian-made firearms. In 2019, it was also reported that the United States Secret Service was making the switch to the 9mm Glock pistols.

However, New Hampshire-based SIG Sauer could be giving the Austrians some competition.

In March, it was announced that the Delaware State Police had adopted SIG Sauer P320RXP pistols as the standard service weapon. The Delaware State Police is a division of the Delaware Department of Public Safety and Homeland Security and is responsible for law enforcement and traffic regulation across the state of Delaware with more than 700 troopers

“We are extremely pleased with our decision to make a department-wide transition to the P320 RXP and incorporate the capability of a red dot optic to our P320 official duty pistols,” said Colonel Melissa Zebley, superintendent of Delaware State Police. “All of our troopers recently completed the training and instruction process with the new pistols and optic and we’ve noticed the outstanding accuracy of the P320 pistol and the pairing with the ROMEO1Pro optics has added a new level of fast, responsive target acquisition.”

The P320RXP, which is being adopted by the Delaware State Police, is a 9mm striker-fired pistol and it also features a factory-installed Electro-Optics ROMEO1PRO Open Reflex sight and suppressor height backup sights, ambidextrous slide catch lever, reversible magazine catch, and a modular polymer grip module available in small, medium, and large.

The pistol also offers an intuitive 3-point takedown, which requires no trigger pull for disassembly, as well as safety features that include a striker safety and disconnect safety.

The ROMEO1Pro red dot sight is available with either 3MOA or 6MOA red dot, and it comes with twelve brightness settings for a full range of light conditions.

It also offers a TruHold Lockless Zeroing System that is designed to endure recoil yet return to zero shot-after-shot. It features a molded glass aspheric lens with high-performance coatings for superior light transmittance and zero distortion.

“As more and more law enforcement agencies are beginning to see the value of red dot optics, and allow them as an option within their agencies, the Delaware State Police is leading the way,” explained Tom Jankiewicz, executive vice president, Law Enforcement Sales at SIG Sauer, Inc.

“This is the very first statewide agency to incorporate a red dot pistol as the department-wide standard, and we are incredibly proud of the positive feedback we have received throughout their transition and training to the SIG Sauer P320 RXP pistols,” added Jankiewicz.

The SIG Sauer P320 has often been compared to the Glock 19, so it could be the domestically-made firearm that gives U.S. law enforcement an alternative to the handguns from Austria.
