"Seattle Slug" in a Glock 20/21SF

[gofastman]

Will the one for the G17 fit the backstrap of the G20SF?

I'd like to add a bit of weight back on the thing when I shoot my AA .22 kit.

I don't think it will fit because the modern Glocks have two molded protrusions in the hole that the older Glock didn't. Take a look in yours, you'll see them.
My slug didn't fit my 17L because of them.
I had to cut part of the slug off.
I don't know if the SF frames have different shaped or sized holes than the standard models.
I had slug in my G-20 and liked it, along with a tungsten guide rod and a 20 pound recoil spring, it took the edge off recoil.

In the link to taylor freelance, their webstore seems to be down, not a good sign.

I did a quick search and found them at brownells, take a look, looks like they have redesigned them since I last bought one.

It doesn't seem that unreasonable to me, looks like a fair amount of machining
