I’ve owned more than a few Glocks. Not one failed to go bang ever. Whether 1000+ rounds or just a couple hundred before I moved it on. While I did replace the sights on a few (mainly to add black sights to see MOS optic dots better), the triggers on all worked just fine. I would have zero qualms running a Glock for a security detail.
If I still possessed any strikers, the majority would be Glock…and one Hellcat running a treaded barrel and compensator kit. But that’s water under the bridge.
