It's pretty light, but you certainly know you have something on your face. I don't get a crisp view, probably because of my eyesight. I've not messed with mine in many weeks. It's the kid's game now.
Well the original grips sucked, so I know why they replaced them. I bet the 600-800 range would be correct. I traded a G43x with optic and light for the same generation P220 not long ago. It is all original and I will likely never shoot it. I've got a P220 Legion if I need to scratch that itch.

My club uses wood strips with rubber matting attached to it, and duct tape to help hold it in place. And Chalk lines for where it is supposed to be. Tape doesn't stick very well on the dirty concrete floor.
I've shot a ton of their 124 Match Winners and they are good. But I've found a source for 125 HAPs for the same price. Much cleaner on the comp and extremely accurate. Shot a 1" group at 25 yards today in an uncomfortable position.
