Mag. Spring too Long?

[Bulldog]

I picked up a 8 rd. 9mm magazine, and I have not shot the gun (CM9) with it in, but test loading rounds it nose dives using the slingshot method on the first round.
The six rd. mag. works just fine, and I've had zero problems with the gun.

Question is, can the spring be too long?
I removed and made sure the spring is installed right, but it seems almost too much spring for the magazine. The eight round wiggles around and does not seem to be lining up with the feed lips. Now one to four rounds seat fine, but the more I load the wiggle room is greater. I have been reading old threads trying to see if this has been answered before, but with no luck.

Now, when I do shoot, it may work fine, and all this will be moot.
But...

Thanks!

The 8-round extended-grip mags are my favorite and I've never had a problem with them. I use them for reload carry with my PM9 and for the range. My K9 is stoked with those and reloads with the pistol.


The springs are only twice the length of the magazine tube and a little trickier to re-install. Usually, stronger is better than weaker springs in Kahrs.

Well, I hope it works OK for you. :)

I'll bet that Bulldog is not a product of Louisiana public schools!

Thanks Guys...

I wonder, has anyone installed a seven round magazine spring into a eight round magazine to see how it functions? My nose dive problem seems to be pressure related, as six rounds in my eight round mag. work and seat fine, but upon adding the seventh and eighth round is when I start to see the wiggle in the top round. I have also found that after loading all eight rounds if I insert and pry up on the rounds in the magazine lock hole (or whatever it is called), the last round seats good against the lips, and does not wiggle at all. AND, it feeds the first round fine using the slingshot method.

Would it be a mute point if it was very quiet? :rolleyes:

if it does anything by shortening the sprig it might not lockopoen on the last round. Be sure to checkthat out.

Check to see if the spring was correctly installed in the magazine. It could have been installed backwards.

Done and rechecked...

A while back, someone with a PM9 posted they installed the 6 round mag spring in the 7 rounder and it corrected their feed problems.

In my experience that spring, just like recoil springs will look long until they take a set. At times the spring won't allow the last round to be inserted for a while.
