I concur with previous comments. Soft shooting, accurate, big punch in a compact package. I prefer the thumb safety but that's individual choice. I have OWB and IWB holsters but rarely carry mine, preferring a snub nose J frame. My .45 Shield is my nightstand gun.
The .45 is a lot "softer" shooting than you'd expect a compact .45 to be.
Yes, it has some kick, but it is more of a big push, instead of the snap of the higher pressure 9mm.
9mm pressure is 35,000 to 38,000 for +P, while the .45 pressure is 18,000 to 21,000 for +P.
You should try a .45 Shield if you know someone that has one or you can rent one somewhere.
Also helping is the bigger grip of the .45 compared to the 9mm or .40 Shield.
I have owned the Shield 1.0 9 mm and now the 2.0 Shield 9 as my carry/night stand gun. I also shoot 1911's @ steel matches, 9 mm & 45, have always loved the .45. I've read many comments on this forum the .45 Shield soft shooting? While I've not shot the .45 Shield and want too, how can that BE as know how the 9 mm recoils as the .45 muzzle jump can't be soft?
