I'm likely to go forward with getting a Gen5 19 and Gen5 17 milled for red dots...but....I'm very tempted to also try out a Brownells slide for one of my Gen3's or for a Gen4 gun.
BTW, I called Brownells and they indeed do not offer their slides for Gen5's.
At this point I'm experiencing analysis paralysis though over what gun I'd get the Brownell's slide for:
a Gen3 G19, a Gen4 G17, or a Gen4 G17...The gun would be used for training, dry and live, to get squared away on RDS's, and for Concealed Carry. I could conceal a G17 quite well AIWB, but I do prefer a G19 for carry.
As far as the G17's go is there an argument one could make for getting a Gen3 as opposed to a Gen4 RMR slide?
Is there a good argument to go G19 vs G17 RDS, or vice versa?
I know very subjective, but I just thought I'd see what all you pistoleros have to say!
