Just buy or piece together a 34 upper.
Yes, they share the same receiver.So... a 34 upper will work on a 17 lower? I didn't know that, I've never looked into changing uppers on any of my guns. Might need to check it out.
+1!!!!!:wow:Get the 35 - and buy a 9mm conversions barrel. It's like having 2 guns in 1.
34 > 17.
I had both at once point as well and simply sold the 17 to make room for a baby Glock.
