Frequently Asked Questions
Is the GLOCK 20SF suitable for concealed carry?
While it is a full-size pistol, its relatively slim profile for a 10mm makes it a viable option for some users, especially with the right holster and attire. Our staff often recommends a proper break-in period of about 50 rounds before relying on any new firearm for carry duty.
Can it shoot .40 S&W ammunition?
No. The GLOCK 20SF is chambered exclusively for 10mm Auto. Firing .40 S&W is unsafe and can cause catastrophic failure. Always use the correct, specified ammunition.
What does “Short Frame” or “SF” mean?
The SF designation indicates a reduced grip circumference compared to the standard GLOCK 20 frame. This modification provides a better fit and more controllable grip for shooters with medium to smaller hands, improving recoil management with the potent 10mm round.
