I sit here reading this and just remembered my shield 40 is on my hip. Yes, I did forget it was there, way easier to carry than my glock 23. I still think the glocks shoots better (for me), but I've been carrying that pistol for 16+ years.
No issues loading my magazines, both of them are tight but not difficult. Next time I get to shoot I'm going to run the IDPA classifier to see how I do. This pistol does have some snap but no worse than my 329PD with full house 240 grain loads
I want some night sights, but no other mods on my mind so far. Only issue so far is some rust around the mag release, it's been 100-110 here in hell lately though.
Make sure you practice with some of your carry loads or a matched load. Real ammo may be hotter than the WWB you're shooting.
And have fun, this is a great pistol!
