Magazine Spring Question

Post by Tim:H11 on Tue Jan 24, 2017 12:13 pm

What is the poundage rating in a typical 7 round, 1911 government model, magazine spring? 

I've heard that some replace these springs with lighter ones for reliability reasons. Which springs should I use and where can I order them?

Wolff has reduced power mag springs. I've never tried them, but maybe someone else knows more about them.

I installed Wolff 6 lb springs and Clark followers all my 7 round mags. Very reliable.

Must vary by pistol, I had to install the Wolff extra power magazine springs and file the lower and forward edge of my extractor to get it to function reliably after my old extractor broke and bought a replacement.

It's standard for me to replace the magazine spring with a Wolff 6lb and verify the angle on the follower.  That combination will allow proper feeding and not create excess drag on the slide during the cycle of operation.  That is the primary reason for the reduced power spring.

so if the things like the mag catch,magazines and springs, and ejector are incorrectly fitted they could cause excess drag?

The mag catch definitely plays a HUGE roll in this scenario.  I had to learn that with the Nelson conversion, IMO you MUST use the mags that come with the conversion.  The receiver will determine what mag catch must be used.  The GSG or now Sig mags are great for a Marvel or Kart but will cause problems with the Nelson.  I think you meant ejector Chris, and yes is you have an extended ejector you must make sure the top of the mag is not hitting the ejector.  There are many things that have to play in unison and harmony to ensure proper feeding.

+1 on KC's  comment on using Nelson magazines for Nelson and magazine catch fitting, especially for conversions. 

The following is from my experience only.  

Kart conversions generally run ok with GSG / Sig or Marvel magazines. Marvel conversions seem to run ok with everybody's mags but Nelsons (seems to be magazine catch issue).  Occasionally, an original Kart magazine will be a little too "tall" to work with a Marvel conversion (fit and ejector interference) and the Kart did not play well at all for me with the Nelson conversion magazines. 

Again, a lot of this goes back to the magazine catch and positioning of the mag. So everyone might have different experiences depending on the magazine catch and how it's positioning the magazine with respect to the barrel / slide.

Just goes to show that we need to set the guns up properly and test everything.
