Glock Recoil Spring Assembly, G26/33/39

Superior versatility is available with this high-performance, 10mm AUTO
pistol. With reduced dimensions compared to the standard size GLOCK
20SF, the subcompact GLOCK 29SF is also suitable for concealed carry. In
addition to the use as a backup weapon for hunting, more and more
security personnel on patrol appreciate the comfortable firing
characteristics and the grip ergonomics of the G29SF 10 mm with a 10
round magazine capacity standard. The SF model reduces the circumference
of the receiver at the rear, or “back strap,” offering increased
comfort and control?especially to shooters with smaller hands.
