Sauer 90 Magnum

About the Sauer

The story of Sauer & Sohn company began way back in the year 1751. The company was founded by Lorenz Sauer in the German city Suhl and until today it still lives up to its reputation as the oldest firearms manufacturing company in Germany. At its very beginnings, the company predominantly focused on producing firearms based on military contracts. The ‘Seven Years War’ in 1753 resulted in the company's first larger orders for the Prussian army.

Almost ninety years later, the eponymous grandson of Johann Paul Sauer started his business unit and around the same time, in 1839, the company changed its name to Spangenberg & Sauer. After the death of co-owner Ferdinand Spangenberg in 1873, Johann Paul Sauer, together with his sons Rudolf and Franz, took over the majority ownership of the company and re-named it to ‘J.P. Sauer & Sohn’. Soon after, the company reached its highest order to that point - approximately 150.000 rifles were produced for the German army. However, the number of military orders decreased severely in the following years, thus forcing the company to find new ways of expanding its market.

As the middle class grew, the demand for civilian arms production increased. The company knew how to exploit this economic situation and consequently presented its first SBS rifle in 1881, followed by the first catalogue which was released one year later. The innovativeness did not stop there – the company's success was at its very beginning, to say the least. As it grew, it began to gradually focus on hunting rifles. Thereupon, the first Sauer self-cocking drilling with a separate cocking lever for the ball lock was presented and launched in 1895. Twenty years later, the company presented the Sauer Meisterwerk XVIII shotgun that boasted sear, single trigger, ejector and engraving by Franz Schilling.

During the First World War, they mostly re-focused on military production and expanded its establishment along with the number of staff. However, the social and economic penury after the war, made the company struggle in the following years. To ensure its survival, the company started producing various products such as typewriters under the name Fortuna; for a short period, they also manufactured bikes. Due to the prohibition of military production, the construction of light hunting rifles was launched in 1930 with the triplet Mod. 30 and Mod. 30 L being introduced the same year and Mod. 32, Mod 32 L, Mod. 33 shortly after.

The shift in production happened again at the beginning of the Second World War when orders for military purposes firearms were increased. After the War, being deleted from the commercial register and under total soviet occupation, the company continued its production under different names - 'VEB FORTUNA Werk Suhl' and later 'VEB MEWA Ernst-Thälmann-Werke Suhl'. At that point, Rolf Sauer sold all company's rights to a group of industrialists in FRG. Nonetheless, the company still used its original name J.P. Sauer & Sohn for the production of hunting rifles years later. In 1951 J.P Sauer & Sohn GmbH was founded as the first hunting rifles manufacturer in FRG.

Soon after some of the most recognizable models were presented, such as Drilling Model 3000, which replaced the famous S53 Drilling, Model 80 bolt action rifle, Sauer 200 (the first modular action rifle in 14 calibres), the S 200 and Sauer 202.

After the year 2000, the ownership changed again when passionate hunters Michael Lüke and Thomas Ortmeier took over. At that turning point, the company shifted to focusing exclusively on the production of hunting rifles, presenting several popular models such as SAUER 303 self-loading rifle, SAUER 101, SAUER 202, SAUER 404, SAUER 404 Synchro XTC, SAUER 100, Sauer S 100, SAUER SL5 and SAUER101 Highland XTC. Nowadays, the brand's vivacious history and tradition of over 270 years result in quality and experience, thus offering an infallible choice for every hunting enthusiast.

Introduction

In recent years we can observe that a trend of Picatinny rail has become widespread and global. It is driven by the NATO standardized rails, more commonly known as the Picatinny rail standard. Picatinny rail being the New Jersey Arsenal that developed it in 1995.

These mounting options are revolutionary. The biggest and best advantage being that the Picatinny rail can be used its entire length and not bordered to a few pre-designed slots like for example the Weaver rail standard was before.

The other main advantage is the ease of use and interchangeability. If a product is meant for a Picatinny rail design it will fit all Picatinny-rails, no matter the manufacturer or date of production.

Picatinny/Weaver Rail

Picatinny Rail and Weaver rail profile

Design

The Picatinny rail is almost exclusively crafted from a single piece of metal (in some cases aluminum). In this manner, the axis of the Picatinny rail is perfectly straight and aligned with the axis of the firearm. Therefore the rifle scope which is mounted onto this kind of configuration is certainly aligned with the rifle / gun and the trajectory of the ammunition.

Weaver rail design on the other hand is usually manufactured in two separate pieces, greatly increasing the possibilities for the axis to be crooked, overlapping, and out of line.

It is always harder to align two separate pieces to a third line than it is to align one piece to another. In this way, the lapping of two mounting rings on a single-piece Picatinny rail is no longer required.

The single-piece rail will assure that both rings are perfectly aligned to each other and that no unwished stress is transferred to the riflescope.

Picatinny compare to Weaver Rail

The Picatinny rail itself is an evolutionary step forward from the older Weaver rail. The main difference between Picatinny rail and Weaver rail is the spacing of the slots. Picatinny rail design has them evenly placed exactly 5.23 mm from one slot to the other, 3 mm deep. For this reason, the mounting options are repeatable and the same as other firearms using the Picatinny rail standard.

Interchangeability was a major driving force in the development of the new standard as different NATO armies need to be compatible with each other.

Weaver rail has 3.8mm wide slots and these slots can be placed anywhere on the Weaver rail and in any number that the producer wished.

Advantages of Picatinny design

A big advantage for using the Picatinny rail design is the ever-present recoil stop. Furthermore, the manufacturing of the rail is not very technically demanding and can be done without the use of state-of-the-art machines which greatly reduces the cost of the finished product, making it very affordable.

The Picatinny rail is easy to mount and usually, this type of configuration does not transfer negative stresses and forces from the fired weapon to the rifle scope.

In addition, the Picatinny rail with its very long useable surface works well for mounting longer rifle scopes or to achieve optimum eye relief.

The durability and toughness are other big pluses for this solution.

Manufacturers of Popular Models

A majority of the Picatinny rings are fixed, but a number of best rated European manufacturers (EAW, MAK,..) have, in recent years, put a lot of effort into the development of detachable ring with100% repeatability, with which it becomes easy to remove the scope from the weapon without the use of tools.

No re-zeroing is needed with such mount options, but these models tend to be expensive.

Weaver and Picatinny Rings

Picatinny rail and weaver rail share one more thing. It is possible to use the Weaver ring and the Picatinny ring on the Picatinny-rails, but it is usually impossible to use the Picatinny ring on the Weaver base. The reason being the above-mentioned positioning and spacing of the slots.

Picatinny mounts have a 5mm recoil stop that goes into the rail slot and since
Weaver rail only has 3.8mm wide slots such rings do not fit on Weaver rails.

Due to this reason, the Picatinny-rails are popular and prevailing on the market in recent years and eventually, these options will completely oust the Weaver rail from the market.
