Pre-Compressed Precision for Target Shooters

The Gamo PR-45 is a pre-compressed pneumatic air pistol that uses a single-stroke cocking system with a top-lever mechanism . Unlike traditional spring-piston pistols, this design compresses air directly during the cocking stroke, eliminating piston bounce and providing a quieter, smoother shooting experience . This pistol is ideal for target shooters and recreational plinkers across Germany, France, Italy, Spain, the Netherlands, Belgium, Poland, Austria, and Denmark who value accuracy at an accessible price point. The PR-45 is characterised by its excellent balance and grip, allowing proper stance and trigger management . At 880 grams, it offers a substantial feel for stable one-handed shooting.

Technical Specifications and Power Delivery

The PR-45 is chambered in 4.5mm (.177) calibre and features a single-shot loading system . Muzzle velocity reaches 120 m/s, with energy output at approximately 3.67 Joules, keeping it safely under 7.5 Joules for EU compliance across all member states . The rifled steel barrel measures 21cm, contributing to the pistol’s overall length of 27.5cm . The cocking effort requires reasonable force to compress the air, but owners report it is manageable for most shooters . The fixed match-style sights are adjustable for both height and windage, with the rear sight notch width also adjustable on some models . The single-stroke pneumatic system provides consistent velocities shot after shot. A 2-year manufacturer’s warranty covers the pistol.

Match-Style Features for Serious Plinking

The PR-45 features fixed, adjustable match-style open sights with a rear sight allowing notch width adjustment . The horizontal trigger provides a comfortable feel and clean break, though owners note it requires some familiarisation . The ambidextrous grip with checked panels ensures a secure hold for both left and right-handed shooters . An ambidextrous manual safety behind the trigger enables safe handling for all users . The pistol is cocked by pushing a button on the back, lifting the top section, inserting a pellet, and returning the upper section with force to compress the air . A non-blowback design ensures all energy is directed towards propelling the pellet .

Operational Considerations and Owner Feedback

Owners report several issues worth noting. The PR-45 is known to develop air leaks over time, typically caused by O-ring or valve seal wear, requiring seal replacement . Many owners have successfully performed DIY repairs using standard 17 x 2.5mm O-rings . The trigger out of the box often has significant resistance and a vague let-off point, causing muzzle movement . Owners describe the controls as wobbly, with the trigger showing noticeable play in all directions . The left-hand grip panel is moulded as part of the lower frame, with only the right-side panel removable for internal access . The safety mechanism contains a small steel ball and spring that can easily go missing during disassembly . The design of the compression tube has changed over the years, with newer versions using a cross pin to secure the valve housing, so owners should check before ordering repair parts.

Accuracy and Pellet Selection

The PR-45 delivers impressive accuracy at 10 to 20 metres, with owners reporting the pistol is “very precise” at these distances . One owner achieved groups with shots “touching” at 10 metres after trigger work . The pre-compressed pneumatic system provides consistent velocities and a recoilless shot cycle, contributing to repeatable accuracy . For optimal performance, owners recommend standard 4.5mm diabolo pellets such as Gamo Match or H&N Excite . The rifled steel barrel ensures consistent pellet stabilisation. The fixed sights require adjustment to suit individual shooting style, with both height and windage available for fine-tuning.

Final Verdict

The Gamo PR-45 is a capable entry-level target pistol that offers excellent value at approximately 139.95 euros, though it is nearly twice the price of the similar Beeman P17 . It excels as a quiet, accurate plinker for garden use, with many owners reporting thousands of shots without major issues . The pistol is also a viable candidate for 10-metre match shooting, though the Gamo Compact version offers a superior trigger and adjustable grips for a higher price . The PR-45 shares the same internal components as the Gamo Compact, with differences limited to the grip frame, trigger mechanism, and safety system . Owners who are willing to undertake simple trigger polishing and seal maintenance will find the PR-45 a rewarding pistol that delivers consistent performance and long-term reliability. At Airgun Store, we recommend the PR-45 for shooters seeking an affordable, accurate pre-compressed pistol for recreational target shooting across.
