One of the more interesting data points to me is how similar the G17 and G45 are in weight (weights listed on Glock website):Originally Posted by Cool Breeze
G17 MOS: 625g
G45 MOS: 616g
That's a difference of only 9 grams; a fraction of the weight difference between mounting a RDS vs Irons. I'd be very surprised if this small reduction in reciprocating mass is impacting recoil impulse.
For those with a G45 and a 17 MOS, could you weigh the respective slides without barrels to see what the actual difference is in reciprocating mass?
This would also help to see if the weights published by Glock are accurate.
