The legendary Shpagin submachine gun, model 1941 (PPSh-41) became a symbol of the Great Patriotic War. Its high reliability and simplicity of design ensured mass production - during the war years more than 6 million units. But one of the key parameters that raises the most questions among collectors, restorers and owners of pneumatic replicas is rate of fire.

Why is the rate of fire so important? The fact is that not only the combat characteristics of the weapon depend on it, but also mechanism resource, firing accuracy, and in the case of modern replicas, even legal aspects of use. In this article we will look at official data, myths, adjustment methods and practical nuances that are not written about in standard reference books.

You will learn:

  • 📊 Real numbers rate of fire of PPSh-41 according to documents and tests
  • ⚙️ How does the design of a weapon affect the rate of fire and is it possible to change it?
  • 🎯 Why a high rate of fire is not always a good thing (and when it becomes a problem)
  • ⚖️ Legal restrictions for replicas and mockups in 2026

Official data: what is the rate of fire of the PPSh-41 according to the documents?

According to Technical description and operating instructions for PPSh-41, approved in 1941, nominal rate of fire amounts to 900–1000 rounds per minute. This figure is often found in reference books, but in practice it varies depending on conditions.

It is important to understand that the rate of fire is theoretical value, calculated under ideal conditions: clean weapons, high-quality lubrication and standard ammunition 7.62×25 mm TT. Real tests show a range from 850 to 1100 shots/minwhich is related to:

  • 🔧 Wear of the shutter and return spring (weapons were often used in battles without proper care)
  • 🌡️ Ambient temperature (in cold weather the lubricant thickens and the temp drops)
  • 💥 Quality of cartridges (serial war ammunition could have different powder charge power)

For comparison: German MP-40 had a rate of fire of about 500–550 shots/min, and American Thompson M1A1 — 600–700 shots/min. Soviet designers deliberately went for an increased rate of fire, sacrificing accuracy for the sake of suppressive fire effect in close combat.

📊 What rate of fire do you consider optimal for the PPSh-41?
800–900 shots/min
900–1000 shots/min (original)
1000–1100 shots/min
Less than 800 for better handling

Design features affecting the rate of fire

The high rate of fire of the PPSh-41 is due to open shutter and free movement of the shutter - the simplest automation circuit, where the recoil energy directly affects the bolt group. Unlike gas-powered weapons (e.g. AK-47), there are no adjustable gas ports or buffer systems.

Key elements that determine the rate of fire:

  1. Return spring - its rigidity and length. The original PPSh used a wire spring with a diameter 1.2 mm with turns pitch 5.5 mm. Over time, it sagged, which increased the pace.
  2. Shutter weight - in PPSh-41 it weighs about 500 grams. The lighter the bolt, the higher the rate of fire (but also the higher the wear).
  3. Gaps between parts — in worn-out weapons they increase, which leads to a “spacing” of the tempo.

Interesting fact: in PPSh-41 model 1942 (simplified version) the return spring has been shortened by 10 mm, which increased the pace by 50–100 shots/min. This was done to simplify production, but worsened the accuracy of fire.

Why does the PPSh fire "_queue" (bursts) even in single player mode?

The original PPSh-41 does not have a fire switch - it only fires automatically. However, in some modifications (for example, PPSh-41/N for the people's militia) a rudimentary safety was installed, which, when pressed incompletely, could simulate single shots. In modern replicas, "queue" is often caused by a weak spring or a dirty sear.

Practical influence of the rate of fire on combat characteristics

A high rate of fire is a double-edged sword. On the one hand, it provides fire density, which is critical in trench battles. On the other hand, it creates several serious problems:

⚠️ Attention: At a pace above 1000 shots/min in the original PPSh-41 there is a risk "seizing" of cartridges - when the next cartridge encounters the previous one, which was not completely removed. This causes delays and can damage the extractor.

The main consequences of high tempo:

Parameter Rate 800–900 shots/min Rate 1000–1100 shots/min
Controllability Shorter fire, easier to keep target Strong barrel lift, dispersion
Ammunition consumption Economical (71 round disc in 4–5 seconds) The disk is emptied in 3 seconds
Wear of mechanisms Moderate (resource ~15,000 shots) Accelerated wear on the bolt and barrel
Tactical effectiveness Better for pinpoint purposes Effective for suppressive fire

Modern replicas (pneumatic, gas) often artificially reduce the tempo to 600–700 shots/min to comply with legislation. For example, in Russia, according to Federal Law No. 150 "On Weapons" layouts should not exceed 450 shots/min with a shot energy of more than 3 J.

💡

If your replica PPSh shoots too quickly and “rips” the plastic cartridges, check the lubrication of the bolt. Often the problem is solved by replacing the return spring with a stiffer one (for example, from PPS-43).

Adjusting the rate of fire in the original PPSh-41 is possible, but has strict limitations. In historical copies (museum, deactivated) any modifications prohibited by law. For replicas and mockups, options depend on the design:

  • ⚙️ Replacing the return spring - the easiest way. A stiffer spring reduces the rate, a softer one increases it. For example, a spring from PPD-40 reduces rate of fire by 100–150 shots/min.
  • 🔨 Shutter modification — increasing the mass (for example, lead inserts) reduces the rate. Lightening the bolt by sawing has the opposite effect.
  • 🛠️ Adjusting the sear - changing the firing angle may increase the delay between shots. Requires precise fitting!
  • ⚠️ Using "buffers" — in modern replicas rubber shock absorbers are installed, but in original weapons this will lead to delays.
⚠️ Attention: In Russia any modifications combat-ready weapons (even deactivated with saved automation) qualify as illegal production according to Art. 223 of the Criminal Code of the Russian Federation. Replicas can only be modified to the extent that they do not turn them into firearms.

For gas cylinder replicas (GBB) rate of fire is adjustable:

  1. Gas pressure (for example, Green Gas vs CO2).
  2. The weight of the moving parts (bolt group).
  3. Setting the gas supply valve (requires disassembly).

Comparison of PPSh-41 with other submachine guns in terms of rate of fire

The PPSh-41 was not a record holder in terms of rate of fire, but it combined a high rate of fire with simplicity and reliability. For comparison:

Model Rate of fire (rounds/min) Notes
PPSh-41 900–1000 Open shutter, free travel of the shutter
PPS-43 600–700 Closed bolt, less wear
MP-40 500–550 Low tempo for better handling
Thompson M1A1 600–700 High weight reduces recoil
Sten Mk II 500–550 Simple design, low reliability

I wonder what Finnish Suomi M-31 (PPSh prototype) had a tempo 900 shots/min, but with the ability to switch to single light. Soviet designers abandoned this in order to simplify production.

Modern analogues (for example, Cedar or Bison) have tempo 600–700 shots/min, which is considered optimal for recoil control. PPSh-41 was “overclocked” in this regard, but this was justified by the tactics of use: short bursts at a distance of up to 100 meters.

💡

The PPSh-41 was designed for mass production and close combat, where a high rate of fire compensated for low accuracy. Modern standards impose different requirements for weapon controllability.

In Russia and most CIS countries, ownership of the original PPSh-41 is possible only in deactivated or museum status. There are strict restrictions for replicas and mockups:

  • 📜 Federal Law No. 150 "On Weapons" (Russia): layouts should not exceed 450 shots/min with muzzle energy over 3 J. For pneumatics with energy up to 3 J There are no restrictions on pace.
  • 🇺🇦 In Ukraine: similar rules, but gas cylinder replicas require permission from the Ministry of Internal Affairs.
  • 🇪🇺 In the EU: according to the directive EU 2021/555, cues with a tempo over 300 shots/min are equivalent to firearms.

Important: Even if your replica shoots plastic balls, exceeding the rate of fire limit may qualify as illegal carrying of weapons. For example, in Russia there is liability for this under Art. 222 of the Criminal Code of the Russian Federation (up to 4 years imprisonment).

⚠️ Attention: When purchasing a replica PPSh-41, be sure to request a certificate of conformity, which indicates the rate of fire. Some Chinese models (CYMA, LCT) are sold with factory temp 800–900 shots/min, which requires improvement before legal use.

How to check the rate of fire yourself?

  1. Use chronometer (smartphone applications like Shot Timer).
  2. Take a video of the shooting and count the frames between shots (at 60 FPS, 10 frames = 1000 shots per minute).
  3. Contact shooting club — there is professional equipment there.

Practical experience: advice from replica owners and collectors

We interviewed owners of original PPSh-41 (deactivated) and replicas to collect real cases:

  • 🔧 “After replacing the spring with a PPSh from the PPS, the rate dropped from 1000 to 850 rounds/min. The accuracy improved, but delays appeared due to contamination.” — Igor, collector, Moscow
  • 🎯 "In a gas-cylinder replica LCT PPSh-41 the tempo was 950 rounds/min. I had to install a foam rubber buffer to keep it to 450." — Alexey, airsoft player, St. Petersburg
  • ⚖️ “I bought a model with a rate of 600 rounds per minute and passed the examination without problems. The main thing is that the shot energy was up to 3 J.” — Dmitry, lawyer, Ekaterinburg

General recommendations:

  • 🛒 Buy replicas only from certified dealers (for example, ASG, Cybergun).
  • 🔧 To reduce the rate of fire in gas-cylinder models, use Green Gas instead of CO2.
  • 📹 Before purchasing, check reviews about a specific model - some Chinese replicas have a “floating” speed.
💡

If you are restoring a historical PPSh-41, never use modern lubricants like WD-40. In the original it was used RChS gun lubricant (recipe: 70% spindle oil + 30% kerosene).

FAQ: answers to frequently asked questions about the rate of fire of the PPSh-41

❓ Is it possible to legally increase the rate of fire in a replica to the original 1000 rds/min?

No. In Russia and most countries this is equivalent to weapon modification. The maximum allowed tempo for layouts is 450 shots/min (at energy above 3 J). For pneumatics with energy up to 3 J there are no restrictions on tempo, but there may be problems with registration.

❓ Why does the original PPSh-41 fire “queue” (in series of 2-3 shots) with one click?

This is a typical problem with worn-out copies. Reasons:

  • Wear whispered (does not lock the shutter in the rear position).
  • Weakening mainspring.
  • Contamination or deformation trigger mechanism.

In replicas, "queue" is often caused by a weak recoil spring or improper assembly.

❓ What is the rate of fire of the PPSh-41 with and without a butt?

The buttstock does not affect the rate of fire - it is determined only automatic mechanism. However, shooting without a stock increases dispersion due to worse handling. The original instructions of the Red Army recommended firing in short bursts (3–5 shots) with the butt resting on the shoulder.

❓ Is it possible to determine the rate of fire by sound?

Approximately - yes. Experienced shooters estimate tempo by ear:

  • 600–700 shots/min - clear individual sounds.
  • 900–1000 shots/min - merging "roar".
  • Over 1100 shots/min - The sound is like a rattle.

For accurate measurements, use timekeeping apps (Shot Timer, Ballistic Calculator).

❓ Which cartridges are best to use for a stable rate of fire?

In the original PPSh-41:

  • 🔹 7.62×25 mm TT (model 1930) - standard ammunition, provides a rate of ~900 rounds/min.
  • 🔹 7.62×25 mm P (model 1943) - with an increased charge, can increase the rate to 1000–1100 rounds/min.
  • 🔹 Training cartridges (with an inert charge) - the rate drops to 700–800 rounds/min.

In replicas, the type of gas or spring affects more than the "cartridges".
