Notes
The Gen4 G34 was the last generation offered without an optics cut. When the Gen5 G34 launched, it was available exclusively in MOS configuration, making the Gen4 the final 'iron sights only' factory G34. The modular backstrap system was a significant ergonomic upgrade, allowing shooters to customize grip circumference with small, medium, and large inserts plus beavertail options. The dual recoil spring assembly softened recoil impulse compared to the Gen3's single spring, contributing to faster follow-up shots in competition.
Background
The G34 Gen4 was the workhorse of USPSA Production division during the early-to-mid 2010s. Its modular backstrap system meant competitors could finally customize their grip without aftermarket modifications, while the dual recoil spring provided a noticeably softer shooting experience in long match stages. When Glock moved to the Gen5 MOS-only configuration, many competition shooters held onto their Gen4s, appreciating the slightly different recoil impulse of the dual-spring system.
