Glock announces voluntary replacement of recoil spring assemblies in Gen4 pistols


( – Glock Inc. is voluntarily exchanging the recoil spring assembly (RSA) on its new Gen4 pistols shipped since August 2009. Consumers should note that Gen4 G26 and G27 models will not require a modified recoil spring.

“We are moving proactively and quickly to standardize this part of the pistol. This is a voluntary exchange specifically for the new Gen4 models,” said Gary Fletcher, vice president of Glock. “We have developed a program for consumers to send in their existing recoil spring assemblies and receive new ones at no cost.”

The replacement of the Gen4 pistol RSA can be performed as part of the regular field-strip process; consumers do not need to take the Gen4 pistol to an armorer. Consumers wishing to participate in the exchange program should call 877-745-8523 to order their new recoil spring.
