A Higher Level The CZ P-07 or the Way to Improve the Duty
Stippled sections on the side of the frame prove useful not only for reliable ‘resting’ of the index finger of the shooting hand outside the trigger but also for reinforced grasp on the gun when held by both hands, with the checkered spot serving as a rest to the thumb of the other hand. These stippled sections have persisted on the modern P-07 as well as its larger sister, the P-09 (see p. 14 for more details). The polymer frame of the P-07 houses two metal frame inserts, one of which was adapted from the subcompact CZ 2075 RAMI P. The top sec tions of these inserts are notched to en gage the slide rails and provide solid guidance during cycling. The rear in sert carries the Omega firing mechanism, with ad ditional rails to secure the back of the slide. The front insert serves to attach the trig ger and slide stop, which is the main connection holding the slide to the frame. The return spring is made of flat wire and it is fit on a long plastic guide. When in the rearmost position, the slide hits a partition in the polymer frame that absorbs a consider able amount of recoil. The slide of the Duty is based on the cur rently most common simplified Brown ing system with open quadrant comprising two hooks and locked by the square‑shaped
rear side of the barrel to fit the size able ejection port. When locked, the slide remains in horizontal posi tion, ensuring direct path for the ammunition to leave the magazine and

travel into the chamber, which makes the feeding process reliable and smooth. The Duty has been fitted with am bidextrous plastic safeties and de ‑cocking levers, the design of which matches the overall shape design of this pistol. The Duty’s hammer was provided with a classic round knurled thumb rest with a large relief hole.
Characteristic features of the model CZ 75 P-07 Duty include the slide with large thumb grooves at the top of the grip and markedly bevelled sides of the slide to simplify drawing and re‑holstering of the fire arm. The new magazine is a very popular feature, it was developed by adaptation of the magazine from the CZ 75 Tactical Sport
Breakthrough by Omega The Omega trigger mechanism has evolved thanks to long‑term experience gained by personnel at the CZ company with respect to the original SA/DA hammer system of CZ 75 pistols, whose excellent user‑friendly pa‑ rameters are balanced by fairly complicated manufacturing and assembly – not to mention its disassembly. The Omega mechanism is still based on the genius idea of design engineer František Koucký using the trigger as a single ‑arm lever to achieve reduced trigger pull and very smooth trigger operation. Patented Omega – this design, mak‑ ing use of technologies developed at the
beginning of 21st century, is transposed into an incomparably simpler form. It still uses the characteristic trigger bar system of the 75, which now rides on a free‑floating roller to reduce friction and smooth out the trigger pull. The trigger parts are of an interlocking design to simplify assembly and disassembly, requiring manipulation of simple modular parts. The service life,
durability and reliability indicators have shifted to measurable threshold levels – while the trigger travel and pull of brand new firearms have reached the level familiar for well seasoned products as the classic 75s. One of the greatest achievements is the ability of the end user to convert from safety to decocking levers quickly and easily.
