This review of the GSG Firefly 22LR pistol highlights its budget-friendly nature and attractive aesthetics, but raises significant concerns about its reliability and factory limitations. The reviewer details a modification to increase magazine capacity using a 3D-printed follower, though this impacts the slide lock-back feature. Issues with suppressor threading and occasional feeding failures are also discussed, making it a pistol with potential but requiring user intervention.

Quick Summary

The GSG Firefly 22LR pistol, while visually appealing and budget-friendly, suffers from reliability issues. Common problems include failures to feed due to a weak slide lock lever and the slide not locking back when using modified magazines with 3D-printed followers. Its barrel also has non-standard European threading, requiring an adapter for common US suppressors.

Frequently Asked Questions

What are the main reliability issues with the GSG Firefly pistol?

The GSG Firefly can experience failures to feed, often due to a weak slide lock lever that bends and rubs against the slide. Additionally, using a 3D-printed follower to increase magazine capacity can prevent the slide from locking back on the last round.

How can the magazine capacity of the GSG Firefly be increased?

The factory 10-round magazine can be modified by replacing the original follower with a 3D-printed one. This modification can allow the magazine to hold 13 to 14 rounds, though it may compromise the slide's ability to lock back after the last shot.

What is the suppressor threading on the GSG Firefly, and is it compatible with standard suppressors?

The GSG Firefly features a non-standard European thread on its barrel. To use common 1/2x28 US suppressors, an adapter will need to be purchased, adding an extra cost and step for suppressor use.

What are the positive aspects of the GSG Firefly pistol?

Positive aspects include its attractive 'awesome looking' aesthetic, similar to Sig Sauer firearms. It also features a normal, easy takedown lever, mimicking designs like the Smith & Wesson Shield, and boasts a good fit and finish with uniform coloring between the slide and polymer frame.
