Glock G21 Gen4 OD Green .45 ACP 13rd Pistol

The GLOCK "Safe Action" pistol is manufactured with only 34 component parts, a significantly lower number of parts than the semi-automatic pistol designs of GLOCK's competitors. This smaller number of component parts increases reliability by reducing the potential for technical problems. The cost associated with spare parts inventory is reduced, which contributes to the lower overall maintenance costs for the life of the GLOCK pistol.
