With its new P250, SIG Sauer has embarked upon a completely novel concept in semi-automatic handguns—the modular pistol. The P250 is based upon a polymer grip module and metal frame/fire control assembly. This assembly is in fact the "pistol," as it bears the serial number, which can be removed and inserted into another grip module.
The P250 is available with two different sized grip modules: Small for the 9mm, .357 SIG, and .40 S&W, and large for the .45 ACP. Both are available in Full, Compact, and Subcompact configurations with three different grip circumferences (two on the Subcompact). In fact, the only difference in the grip modules is the length of the grip itself. Any size grip module will accept the Full, Compact, and Subcompact slide assemblies. To further adapt the pistol to a variety of hand sizes, it can be ordered with either a long or short trigger.
This variety of features allows the shooter to assemble an almost unlimited number of configurations. In addition, the SIG P250 uses 30- to 40-percent fewer parts than a traditional semi-automatic pistol, which streamlines maintenance, spare parts costs, and inventory.
For even more adaptability, the SIG P250 comes standard with ambidextrous slide catch levers. Also, the magazine release button can be switched to the right side so as to accommodate the lefties among us.
Switching it Up
Changing the P250's modular frame/fire control assembly from one grip module can be accomplished in a matter of seconds. First, remove the slide assembly; then rotate and pull the takedown lever out of the frame. Pulling up on the front frame rails while drawing the hammer back frees the frame assembly from the grip module.
To reinstall the frame assembly into another grip module, insert the frame locking tab at the rear of the assembly into the matching slot inside the rear of the grip module, pull back on the hammer to move the trigger rearward, and push the unit in the grip module. Reinsert the takedown lever, install the slide assembly (or another one), and the pistol is ready to go.
For the sake of argument, let's say your agency adopts the Full Size P250 in .40 caliber and each officer has the choice of small, medium, or large grip circumferences with a standard or short trigger. Then, down the road you are given a plainclothes assignment and decide that a smaller pistol would be more practical. In the past, this would mean you would need to be issued an entirely new pistol. Not so with the P250.
All your department armorer has to do is take a Subcompact grip module and slide assembly, remove the frame/fire control assembly from your Full-Size pistol, and install it on the Compact module with the shorter slide and barrel. While you now have a compact handgun, it uses the original frame/fire control assembly with the same serial number, which can greatly reduce paperwork and inventory considerations.
Perhaps your department is one of those that requires you to use the issue pistol for off-duty carry. If that is the case, all you need to do is obtain a Subcompact grip module and slide assembly and install your frame/fire control assembly into it. Voila, you now have an easily concealable, lightweight pistol for off-duty carry.
Wouldn't it be convenient to be able to use inexpensive 9mm ammunition for training purposes? Well if your department uses the P250 all you need to do is purchase 9mm slide assemblies and magazines and install them on your frame/fire control assemblies.
Suppose your agency initiates an "officer's choice" service pistol policy and you decide you would like to carry a .357 instead of a .40. All that is required is to change the barrel and recoil spring. Perhaps you choose to upgrade to a .45 caliber handgun. You obtain a .45 caliber grip module, slide assembly, and magazines, and drop your frame/fire control assembly from your .40 caliber pistol into it and you're ready to go. You can also change your pistol back to any of the previous configurations any time you feel like it.
