I have a couple without external safeties. The idea is to carry them in a fitted holster that covers the trigger. Kydex holsters are like $25 or $30 for any given model, it’s a no-brainer.
Also, they have internal safeties to prevent firing when dropped. Also, they have long and hard trigger pulls.
Don’t buy those guns idiots
You need to pass this wisdom on to thousands and thousands of police and military forces across the planet. Because Glock.
