I was wondering if anyone could settle an argument for me. The debate was: Is there a difference between the dual recoil springs issued with the Gen 4 Glock 17 and Glock 22? Are the 17 springs weaker/have less tension? The reason I ask is because I am shooting hand loaded 9mm from a Gen 4 Glock 22 with a drop in barrel and I keep getting a lot of FTE/stovepipes. The reason that I think is because my powder charge is too light but my buddy said its cause the Glock 22 recoil spring is too much for 9mm loads.
 
New (updated gen4) springs are different. Also, keep in mind G22 slide and 40-9 conversion barrel are both heavier.

x2...springs for the G17 and G22 are different as per chart above. The springs were the same when the very first Gen 4's came out. There was problems with FTE's on the G17's because the spring was too strong.
 
Great chart!

I has my latest RSA in my Glock 17 Gen 4 out today and it cycled my light reloads better than the stock Gen 3 spring I had in there earlier with the Gen 3 conversion adapter.

The reloads would never function with the first 2 previous Glock Gen 4 RSA's.
 
I believe the old style springs were the same for both the G17&22.
The Gen.4's initially were the same, but then proved to be too much for the 9x19 so Glock made a 17/34 specific setup for the G4's.

Glock suggests replacement of spring on old Glocks after 1000rnds.
Apparently Glock now suggests new springs after 5000rnds with the Gen.4 spring setup.

BTW, this is just crap that I've gleaned off of various other forums fwiw.

~Cheers
