I'm thinking of having one of my GLOCKS, fitted with a thumb safety

 

Was playing with a Glock that had a thumb safety and a silencer..was rather strange....did not like it, did not feel natural, you had to position the thumb in a award angle.position & it would be very easy to miss/forget about the safety in a high stress time..

Now the can on the other hand....woza.....

 

Last night I caught one of my Glocks trying to low crawl out the front door to go ND on a bunch of babies.... Will an external saftey prevent this?

 

you see, you can't trust those glocks
