So just FYI, I know the Sig P938 and P238 are practically mini 1911's. But there is one big difference. There is NO grip safety on the Sigs. That being said, on a 1911, in order for that hammer to fall, you really need to disengage the thumb safety PLUS disengage the grip safety. The Sigs only require you to disengage the thumb safety. That's kind of a big difference to me. Keep in mind, I've never owned a P938/238. I've talked to some people recently that have and I've heard more than once that the thumb safety didn't seem to be that sturdy. In other words, it seemed quite easy to disengage it and they had concerns that it might disengage accidentally. I'm skeptical on this, but it's definitely something to be mindful of. I would think that if you have it in a quality Kydex holster, such as the Cook's the OP mentioned, and it's molded in the engaged position, the chance of it being disengaged accidentally are slim.
I, too, am still considering switching to it for a summer carry, but the lack of a grip safety has made me hesitant (they're also not that cheap compared to a $350 Kahr CM9).
I've been carrying the Sig P938 for about 8 months now. The safety hasn't disengaged on it's own yet.
Hopefully if it ever does I'll notice, I try to stay in touch with whatever I'm carrying.
That Sig OWB holster keeps the whole gun and especially the trigger area well covered.
. It was just a hold over from working with the 1911 so much.
