How often do you change your recoil springs? Do you go by round count or do you measure the old one with a new one to see how much shorter the older one is next to the new one, also, when you change the recoil spring, do you also change the firing pin/striker spring also. I usually go by round count.

I swap mine out after every 5,000 rounds. I do not change the firing pin unless after being inspected shows signs of serious wear, cracks, and so on. I have shot thousands of rounds so far and have not replaced the firing pin or firing pin spring in my XDm yet. And this is for the polymer pistol.
My 1911 standard scheduled maintenance is to disassemble and thoroughly clean and inspect all parts every 5,000.
 
I do it around 5-8k round count usually. On my Desert Eagle I only get around 2k, and theres 4 springs. Some of my polymer guns I can tell it needs it when the recoil gets stronger with light loads.
 
So what about AR Buffer springs? My 300 Black Out Springfield pistol won’t shoot subsonic because what I’m being told is the buffer spring is not allowing the gun to cycle on the heavier grain round. Would love to here from the experts on this forum on my options.
 
I doubt it's a buffer spring issue if your 300 blackout pistol is fairly new. There are pressure differences between supersonic and subsonic ammunition. The Springfield Armory 300 blackout pistol is made with a adjustable gas block. So try considering adjusting your gas block.
 
I'm thinking that the heavier subsonic bullet's require a suppressor. The 300 blackout is meant to be used suppressed and thats why its under gassed. And without the extra back pressure from a suppressor it will do what its doing with the heavier loads. When opening up your gas port all the way, your not guaranteed exact pressure to cycle properly using heavy loads of subsonic ammunition without a suppressor.
 
So can I counter that with a slightly lighter duty or “shorter“ spring? I’ve been told the buffer spring in my AR Pistol is an H1 and a H3 would help my issue or I could shorten the spring that came with the gun. Since I’m against cutting up my current spring I’m looking for other options.
 
Okay the real issue here is is not adjusting the rifle at all, altering the buffer spring and or buffer is not the right answer. The real issue here is trying to shoot subsonic ammo without a suppressor. The rifle is fine. Consider shooting ammo that is not subsonic and watch it cycle as intended.

I agree I have found that 150 grain and lighter shoot like a champ.
