So, seems like all I need is a barrel and mags. I have mags for the 20. Hunting down someone's old barrel from when they got something fancy.
What's up with the guide rod and recoil spring? I've seen a couple people mention swapping them with some mention that the G20 slide is a bit heavier than a 21 slide (any truth to that?), but that the G20 and 21 actually have the same recoil guide rod and spring rate.
Also, is the G17 the same guide rod and spring? I am referring to the gen 3 for all of these here.
I am wondering in part because I've got a Wolff SS guide rod for my 17, that I don't use in it and I think 18 and 19# springs (at least an 18#, but I think I'd gotten 18 and 19 and not a 17 and an 18#). I've seen mention of using 21# in a caliber conversion, but I figure a 19# is at least a start.
With the current ammo shortage its not like I am planning on investing in thousands of rounds. I am looking to get 100-150 and barrel and once I can get to a range, just mostly function check it. A fun, not so rainy day, project.
I'll worry about ultimate reliability and/or not battering the frame/locking block pin apart later (unless of course 50-100 rounds is going to bend things up).
Some day I'd build a 20 slide, but those funds are better spent elsewhere.
So I guess to lay it out
1) all I REALLY need is swap the barrel and the mags
2) Is the G20 and G21 slide the same weight wise?
3) Do the G20 and G21 use the same recoil guide rod spring rate?
4) Is a G17 guide rod the same as the G20 and G21, so I can use my G17 SS guide rod with a heavier weight spring (and also what weight, but would stepping it up even to just 18 or 19 be okay, if not ideal)?
Thanks!
