Use the correct parts for each pistol, 40 models and 9 models do have differences.
Hey Rayzorloo,
Is this the same problem with your FTF issues on the gun? Or another one?
I use a Lone Wolf 9mm barrel along with the normal .40 on my 22 and the factory .40 recoil spring works with both. Not had a slide lock back, FTF or FTE so far. Mine’s a Gen 3 as I believe is yours?
Hey, yes this is the same gun/issue I'm trying to figure out. Mine is a Gen4 and the recoil spring is marked as a 9mm. If I had a 40 recoil spring on the 9 I may be fine but maybe the 9 recoil spring not quite strong enough to cycle a 40 round? I shot my reloads on it with a load of TG 4.4 and a 180gr bullet. Sort of a mid range load up.
The recoil spring assembly is different between a Gen 3 and 4. Did you have any luck finding the .40 spring? I was sent what I believe to be a Gen4 recoil spring assembly with my Gen3 22 as it doesn’t fit my gun but I don’t own a Gen 4 to confirm. I can send it to you as it’s surplus to my needs. PM me if you want it to try and hopefully solve your issue.
If your slide locks back, I would assume the 9mm spring would have sufficient power to drive it that far?
Nothing. You cover shipping! Like I said, not even sure it'll fit or work and I don't need it. For all I know, the spring may not even be for a Glock or a .40. The guy I bought it from never got back to me as to what it actually fit.
Although based on what I can tell, it very much looks correct.
