Why? You want at least a 16lb spring in a standard 5" for shooting ball or the equivalent unless you like the pistol battering itself. Personally for hardball or equivalent, I use an 18lb spring, same as I did starting over 40 years ago.Start w
Start with the obvious:
Round count on springs including magazine springs?
What kind of magazines are you using? There are quality magazines out there that pretty much remove the need for that until they do start to fail which is a long way down the round.
If you shoot it, clean it. That pretty much removes the another potential source of problems.Cleaning regimen?
1) How are you shooting it? One hand? Triangulated? Weaver? You haven't let us know.Shooter experience/ability?
Short stroking/"Limp wristing" as mentioned above? Have a more experienced shooter shoot the thing!
I have a very old shooting buddy who's a great shot, but he's mainly revolvers. He's the first person that got my USGI 1911A1NM to stovepipe. So I cleared it and watched him shoot it. He was limp wristing it.
The 1911 platform likes a solid backing to function, be it one handed, triangulated, weaver or whatever.
There is also a very simple drill to clear stovepipes.
