Hi. Can anyone with experience give me some input on what, if any, differences I would notice re recoil without causing malfunctions by changing the recoil spring weight in my new 34MOS? I'm replacing the stock one with a stainless steel guide rod, and the new spring is same as OEM, 17lb. I'll be shooting 124gr ball or hp out of it. Hard for me to find anything definitive.
I can handle recoil on a 9mm, i'm just curious how much the gun can be tweaked by that spring lb.
Thanks for any input.
It's not going to change anything. The only time the weight of the spring becomes an issue is when you start building custom loads, i.e. "soft" loads will require a lighter spring for the gun to operate and "hotter" tend to like heavier spring weights to help control the slide. If you run a compensator then the spring weights and loads have to be tuned so the gun will cycle and maintain accuracy. The gun pictured in my avatar has a stainless rod with a 17# spring and it shoots like a dream. My loads 3.4gr TG and 147gr Xtreme HP. Chrono average 890fps. 3.4 is middle of the road for powder if I go below 3.2 then I have to change my recoil spring because it cycles too fast and stove pipes. By keeping the spring weight at OEM I can shoot my ammo or factory ammo with no issues.
