When do you need a lighter or heavier spring?

Once I got about a dozen of malfunctions in one box with reloads do to underpowered charge, it was obvious that the standard recoil spring was WAY too heavy for the load. But what if you get say one FTE and one FTF out of a 100 rounds (with reloads/ starting charge ) can you blame the spring or would this be guns fault (reliability issue)? :confused:

How do you guys decide when you need different weight recoil spring ?

I would only ever assume a problem with the pistol if it was having problems with retail ammunition (excluding Winclean; I had a Glock which would FTE very often with Winclean ammo), otherwise play with the spring weights until you get what works :)

Are you continuing to shoot them, how many rounds of those have you got? I wouldn't bother changing if it only happens one out of 100 rounds, I would just use a more powerful load instead.
 
If one of my sigs was doing that I would adjust the load before I started changing out springs. Does it seem to cycle fine (ie: slide locks back on an empty mag etc.) If it's not cycling that well you could use a reduced power spring to help. It took me a while to get a good spring & load combination worked out. Then when I had that figured I tried a different load and it tightened up my groups and I had to go back to stock springs. Not sure if that made any sense, but I would not put up with that kind of performance. I would do some load tinkering and then spring tinkering.
 
In my case my CZ eject brass over eight feet and fly all over the place, I should put a heavier spring or reduce the charge a little bit but I haven't do it yet. But walk a longer distance to pick up the brass is pain in the ass.

I would suggest you compare the OAL and bullet type with factory ammo and change to a slower burn rate powder like HS6 and see the result. Some gun just too picky for ammo.

Come on big boy unless you're a midget eight feet takes you like three steps to reach. :dancingbanana: :D
 
"...a dozen of malfunctions in one box with reloads..." That indicates poorly loaded ammo.
"...starting charge..." That doesn't really indicate anything. Work up the load and then think about changing springs. Generally though, a hot load that is accurate, but bashes the pistol would be a reason to change springs. So too would an accurate target load that fails to cycle.
