Makarov pistol upgraded
As with any other weapon, the PM is also subjected to various modifications and upgrades. At the end of the last century, the designers have created a modernization of the PM, who went to the series and is used in service. The main idea of modernization — to improve the characteristics of the PM due to enhanced high-momentum munition "57N181SM" 9×18 mm caliber. Designers and R.Shigapov B.Pletsky designed for the new upgraded gun ammunition, which was announced in '94. Upgraded gun used in the units of the Ministry of the Interior.
At first glance, the PMM is different from the PM increased more convenient plastic handle. At the end of the handle has a notch that allows you to more securely hold the gun. The gun shop is provided by 8-row performance ammunition or 2-row version for 12 munitions. Modern guns are widely used magazine capacity more than a dozen weapons. This was one of the problems of modernization gun. 2-row store tapers towards the upper part, remained neck-row execution. This allowed the bolt and leave the nest for the store unchanged. New helical grooves in the chamber, set up to use the new high-momentum PM for enhanced weapon, despite the dissipation of the increased pressure of powder gases in the channel. Lightly stepping forward cover store, increases the support for the palm of your hand, allowing you to slightly increase the rate of recharge. The pressure in the wellbore using a new weapon has grown by about 15 percent. On capacity utilization of ammunition 9×18 mm caliber parabellumnym almost equal to 9×19-mm ammunition, and that without a large increase in output and pressure gun. But the use of ammunition "57N181SM" in the usual Makarov pistol fail — structurally it is not designed for any increase in the pressure of powder gases. After all, even when fired from a pistol upgraded acoustic cotton grown due to the increased pressure by 20 percent the muzzle of the gun.
Other modifications based on PM
Izhevsk Mechanical Plant has released version of the pistol PM called IL-70 or Baikal. Option is available as an export model. The main difference between IL-70 from the standard Makarov pistol — adjustable sight, made the type of sporting sight. But athletic career at the IZH-70 is questionable.
Another option — IL-70-17A. Also appeared on the arms market in '94. The main difference — the use of .380 ACP ammunition.

Outwardly, everything, "IL-70", going to the external market is quite diverse. Popular overseas domestic "Makarov" is mainly due to the low cost compared to competitors in the market.
The domestic version of the pistol on the basis of the PM as a service weapon — IL-71. The gun is designed for security units and units of the private security sector. IL-71 has turned out as an intermediate gun battle between weapons and weapons for pocket carry. Developed under the gun ammo "Kurtz" 9h17-mm caliber. The cartridge is made with a short sleeve and the reduced diameter of the bullet, according to requirements. By law, the muzzle energy should not exceed 300 J. Cartridge is a kind of option ammunition .380 ACP bullet with a lead core. It is this cartridge is made possible use of military service as an MP in the IZH-71. Weight IZH-71 — 730 grams, has a larger grip and increased store by 10 ammunition, equipped with a mechanical sight.
Another development Izhevsk factory — IL-70-400. At 93, the designer presented the option P.Ivshin Makarov pistol under parabellumny 9×19-mm ammunition. The main difference between a gun — slow unlocking of the barrel, using a screw-ring grooves in the chamber. Gate-guard gun IZH-70-400 from the standard weight by 30 grams PM.
