Does anyone use this to conceal carry?

I conceal carry with this belt almost daily. No problems and no printing. Its rigid so it holds up well. In fact, I find it easier to deal with adjusting in public when you don't really want to show.

In the description it says 22" to 44". When I order the belt it came as 22". How are you supposed to make it a 44" belt when the belt is only 22"?

If it came that short you should send it back. It should be over 44" and you cut it to the size you need. (That is where their instructions could be better. I recommend you check out the YouTube video demonstrating the process.)

Is this full grain, top grain, bottom grain, bonded or what?

To be honest Im not a 100% sure, I think its bonded, my son who I purchased it for thinks its top grain, its definitely not full grain

What kind of metal is the belt buckle?

The release button/lever broke before I wore this thing 10 times. That's less than 10 times of gentle use (dress pants). Buy some other brand and save yourself the time. I had to cut the thing off to get undressed.
