I wouldn't carry the Browning. I had one, and loved it, but wouldn't carry it. Like already said by others, I wouldn't trust it, but that's not the only thing against it.
The thumb safety is very small, so besides being easy to "miss", it doesn't give you much leverage to take it off. It isn't that hard to move, but you just don't have much to move it with.
The sights are almost useless on the Browning. I said "almost" because there may be someone who can use them. I could not, and never found anyone who could. Walther sights aren't the very best, but they are fantastic by comparison.
