Very impressed with mine, my first 320 series. Hoping the romeo-1t comes along sooner rather than later.
I do really like the positive action of the thumb safety on these. Prefer it to the M&P 2.0 Compact w/safety that I played with as it's a little less obtrusive and more positive off/on.
Seriously thinking of trying a Compact w/safety and subcompact frame combo.
