Yeah wonder what there going to do with shield 45. It already has improved trigger and grip like the 2.0 anyway I really like the aggressive grip and improved trigger over my old shield 9. I also have the m&P 2.0 full size which I really like a lot.
I think the Shield 45 has most of the enhancements already, that the Shield 2.0 brings to the 9 and 40 models, except the integrated laser, which as far as I know, isn't available on the 45. I noticed that the 2.0 line doesn't include a 45, thus my reasoning.
