M-Arms shocked the shooting community on March 1st, 2024 at the 50th anniversary of Europe's largest firearms fair IWA Outdoor Classics '24 - this time with an innovation on 2011 sector with a semi-automatic pistol called Aion.Aion distinguishes itself from other double-stack and 2011 pistol models already from outside appearance, but it is also specifical in terms of internal structure, engineering and method of production, as its features significantly contribute to its improved precision. M- Arms managed to integrate and incorporate into a 2011 model all thefeatures of the Aion's predecessor, i.e. 1911 Kratos and thus set an important milestone in the spectrum of double-stack 2011 pistols.
In the following, we list the features and thus also the innovations that distinguish Aion as a cutting edge product from other 2011 pistols on the market.
All parts are milled or done with unconventional technologies from solid blocks of tool steel.
The slide is heat treated three (3) times and DLC coated with the hardness of 93 Rockwells.
External extractor is pin retained with a torsion spring for a long lasting durability since it doesn’t lose pressure. Such a combination of the slide and extractor allows a much better case extraction at lower spring forces as well as different cases, which are more out of tolerance (advantage for reloaded ammo).
Safeties have more interlocking surfaces since they are interlocked from the left and at the right part. Rollover disconnector allows the slide to glide over it for which it allows less friction and thus a faster cycling and, which ensures a higher level of security and smoother operation/repetition (cycling).
The safeties and slide stop are milled from solid blocks and additionally heat treated.
A fully cylindrical rifled bul barrel heat treated into the core with straight locking lugs for faster cycling. A spherical bushing on a bul barrel, which enables an upscaled precision and accuracy while shooting. Additionally it enables smoother operation and durability.
More material on the barrel at the barrel link spot for less possibility of breaking it. A double ramp for a more reliable functioning with loaded ammo (also with flat point ammo/bullets).
Grip safety can be (de)activated with a screw by the shooter with one integrated screw.
Multiple spring system in the mainspring housing enables a better acceleration of the hammer also with lower forces during activation and reduces the frictional forces inside the mainspring housing. The system is integrated from the outside of the frame, therefore the springs can be changed by the shooters themselves without disassembling the gun.
Trigger bow is made from a solid block ( which noticeably contributes to reliable operation and stiffness) and is structurally designed to allow minimal friction and a perfect match with other parts of the trigger mechanism (sear, disconnector). All the friction that occurs due to offsets-triggering is the rolling friction and thus almost zero.
The hammer and internal crucial parts of the trigger are done within the tolerances between 3 to max. 5 micrones (i.e. 0.003 - 0.005 mm) of tolerances.
The pistol housing allows less friction in the part of the trigger mechanism and adjustment of the trigger (Pretravel – Overtravel) without disassembling the whole pistol. The shooter just removes the slide and sets the trigger with a screwdriver by himself.
Apper and lower frames are connected vertically with a huge screw so the frame is not prone to breaking. In the back of the frame there are 2 precision bushings and 2 screws that hold the frame in place. The cut is made in the height of the trigger bow which allows huge tolerances and action within the whole trigger mechanism.
