A semi-automatic pistol variant combines a standard-size frame with a longer, heavier barrel. This configuration typically enhances accuracy and recoil control, making it popular among competitive shooters and those seeking improved performance. The longer barrel also often increases muzzle velocity, which can be a relevant factor depending on the specific ammunition used.
The increased barrel length and weight offer several advantages. The longer sight radius aids in precise aiming, while the added weight reduces muzzle flip, allowing for faster follow-up shots. This setup is often preferred in competition shooting disciplines where accuracy and speed are paramount. Historically, such modifications have been adopted by both civilian and professional users seeking to optimize handgun performance for specific needs.
