magazine changes slower even though it greatly reduces the chances of an accidental magazine release. The heel-mounted magazine release lever also reduces the incidence of lost magazines in combat as a result of speed reloading magazines, as is common with the push button magazine release which only requires the user to push this button to eject the magazine rather than drag it out by hand as one must do with the heel-mounted magazine release lever. P225-A1 P225-A1 was introduced by SIG in 2015. It was based on the P225, with a number of refinements. Notably, the place of origin on the slide was SIG Sauer Inc. of Exeter, New Hampshire. There was a new contour to the frame, a short reset trigger, a milled slide (the earlier one was stamped), and two barrel lengths (one standard and the other threaded for a suppressor). The suppressor model came with high sights. The P225-A1 was discontinued in late 2019. P245 The SIG P245 variant is chambered only in .45 ACP (hence the name) and was developed primarily for the US market as a civilian's concealed sidearm, or as a police backup weapon. The SIG P245 has a reversible magazine release giving the user the choice of operating it with their left or right thumb. It normally takes 6-round magazines, but can also accept the 7-, 8-, or 10-round magazines designed for the P220. A grip extender is available for use with these longer magazines. One of the major differences in construction between the P245 and the P220 Compact is that the P245 was only built using the older stamped steel slide design with a removable breech block, while some of the later P220 Compact variants were available with an extended grip tang. The P245 is no longer manufactured by SIG, having been replaced by the P220 Carry and the P220 Compact.
