Honestly that sounds a bit dystopian. I'd never live in a place where I could possibly be in any danger of being gunned down on the streets. If we had a 2nd Amemdment over here I would keep a gun at home just in case of the one in a trillion chance of a burglarly, but having to carry a gun to Mass? What sort of place do you live in? 

You don't get to choose the day, hour and place where evil comes to you. You need to be ready at all times.

Normalcy bias can be fatal.

I mean a tank could also come rolling down the street and then my concealed carry pistol wouldn't save me, but that's not likely to happen is it?

At my SSPX chapel, I have seen or heard of the following things:

1) Gang fight on the front sidewalk (with pitbulls, pipes, and all), so that the parishioners couldn't leave, and we wondered whether the fight would spill into the Church;

2) A guy pulled out a hammer and started pounding away at the pulpit until he got jumped by the faithful;

3) A month ago, an off duty cop had to subdue some weirdo who came into the church yelling loudly in the vestibule, causing the ushers to grab the attention of the cop to handle the situation;

4) Related to #1, sketchy drug addicts living right next door to church, once causing the priest I was with to fear to walk past them to his lodgings.  Because I was open carrying that day, I was able to escort him;

5) One guy, a professional lech, tried to move in on my mother, and was pressuring her to let him live with her.  I was about to body slam him in the church basement when the priest called us into his office and banned him from the chapel.  Wouldn't have needed a gun for that, but the point being that trads attract weirdos, and we are all targets.

So I guess I agree with Quiddy: Better to have one and not need it, than to need it and not have it.

Besides, unlike some other religions, I always got the feeling that the trad priests were reassured knowing several known and reliable people carried at every Mass.

If you die because of someone's hatred of the Catholic Faith then you go straight to heaven as a holy martyr.

Not necessiarily so. You don't go to Heaven on someone else's hatred. You go to heaven on your own love for God.
THere is no reward for stopping a bullet or whatever. We need to earn heaven by the life and death we live.

Where is this SSPX chapel?

A handful of men, some ex or off-duty law enforcement, discretely carry handguns at the chapel I attend. It's in a bad neighborhood. Knowing one or two are there at any given time makes me feel safer. Also, I feel (almost) bad for any terrorist or looney who wanders in thinking he's going to pull off an easy slaughter of Christians.

I don't think there are places that shitty in my entire country.
