I'm a fan of reliability and accuracy. I can get used to carrying something that feels different or is "heavy" is it's reliable and accurate in my hands.
My carry is a P07. I have carried P01s. I mean concealed carry.
Striker fired pistols? Still looking for one that shoots like the P07 and P01.
Are they okay shooting the groups they shoot? I'm still struggling with that.
I will say that the M&P Performance Center Shield 9MM I bought for her a few months back is the most accurate striker fired gun I've ever shot. I shoot smaller groups with it (and hot 115 grain hollow points) than with the full sized M&Ps, the XDMs, the Browning, the Beretta, the Glock and maybe some others I've left out. Yeah, it shoots better groups than some hammer fired pistols.
People on the M&P Forum tell me the Shields have a different barrel lock up design that the full sized pistols. Maybe that's why it shoots better.
You can buy M&P Compact striker fired pistols with thumb safeties. Takes some aftermarket parts to make them shoot better. To be fair, every now and then you can buy a CZ that won't shoot as good as many of them do.
S&W is making a couple pistols now that look like striker fired pistols (no visible hammer) but have internal hammers. The .380 EZ and the new 9MM EZ. The .380 EZ I bought has been reliable, but not accurate. Those have a grip safety on the back of the frame. And you can get a version of it with thumb safeties, too.
If the aim is concealed carry, add holster availability, magazine cost, and possible replacement sight availability to your research.
