Watch the video below to watch Dennis Adler convert a full size P320 into a Carry model!

While a modular pistol, revolver or semi-auto is not a new idea, nor is a removable fire control housing, Sig Sauer has come up with the easiest and most efficient design for changing grip sizes, frames, slide/barrel lengths and even calibers of any semi-auto in history with the P320.

The P320 is Sig’s first polymer-framed, striker-fired handgun design, ever. A consummate striker-fired, double-action-only (DAO) design, it can be equipped with two different trigger systems (one with an integral trigger blade safety), but it has an improved action with a partially pre-tensioned striker and a short, crisp trigger pull with a quick, pronounced reset. The P320 was engineered to eschew any external feature that can detract from the pistol’s fast handling. The clean exterior design has no external safety or decocking lever to catch or hang up on a draw from concealment.

As a DAO design, the P320 has second-strike capability, and with both front and rear serrations, the slide is very easy to manipulate with either hand as situations dictate. The slide release is ample in size and easy to operate; it is also ambidextrous and integral with the fire control housing. The triangular, serrated magazine release built into the P320’s polymer frame is raised and well positioned to be easily operated by the strong-hand thumb. It is also reversible for left-handed operators.

Many companies offer interchangeable backstrap panels, but Sig went with interchangeable frames—available in three sizes: small, medium and large—for either the Full Size or Carry models, each sold separately. Being able to change frames also means being able to change frame size. So once you purchase a P320 Carry or a P320 Full Size model, it is possible to change frame sizes and make a Full Size into a Carry model, or vice versa, depending upon your initial purchase.

The P320 system also allows for changing calibers from 9mm to .40 S&W or .357 Sig. The .45 ACP will be added shortly, and all changes can be done with the same frames.

Just how easy is it to convert a Full Size P320 into a Carry model? Watch as PersonalDefenseWorld.com’s Dennis Adler demonstrates! Look for an upcoming review of the Sig P320 Carry in an upcoming issue of COMBAT HANDGUNS.

    DAO? The only function the trigger bar seems to have is to drop the sear away from the firing pin. Most technical definitions would call that single action.
