First off, let me say I do carry a folder.

Things would have to be B-A-D before I'd consider using it in self defense though.

My daily carry is a Glock 37 that's been trimmed to match the G17 longslide I've carried for the previous 8 or 9 years.

When I was doing such things - and much younger - we got a lesson on knife fighting. You know what I came away from that understanding? If you get into a knife fight, the one that is called the winner is the one bleeding slightly less. No thanks.

So if someone does something that makes me say "I've got to force him to stop that RIGHT NOW", I'm not going to put myself in a position to get cut up. That's what the Glock is for.

One of the courses I took was at Front Sight - and one of the best things they provided at Front Sight was the after-shooting education. For me, I'd MUCH rather have a grand jury look at pictures of a dead guy still holding a knife and then me with the slightly less weighty magazine in the Glock...... than have that grand jury look at pictures of a body that would be more appropriate to a slaughterhouse or a Tarrentino flick, and have to say "honestly Judge, I had to stab him 28 times to get him to stop!".

As always, this opinion is worth at least double what you paid for it.
