I have heard that the Sub 9 is shipped with a spring that handles a hotter load than the ammo you buy off the shelf and the stiffness in the spring is what accounts for the occasional ejector port jamming. I have also heard that Kel-Tec will adjust or replace the spring for no charge. My question is should you do it or will the spring that is in there eventually "loosen" up and handle the standard loads. I am currently shooting a variety of different 9mm ammo in a S&W Sub 9. I find that in the 30rd clip I am using if I squeeze off rounds in rapid sequence I have more of a chance of getting the jam. Your thoughts and comments would be appreciated.

Regards

I'd be tempted to suspect the 30 rd MAGAZINE rather than the spring for your ejection/feed problems. The heavier spring was never intended to be used for hotter ammo... it was intended for use in the .40 caliber version. It just happened to absorb some of the recoil better in +P ammo so people went on a heavy spring binge... even though replacing the spring STILL doesn't make a 9mm SUB capable of standing up to consistant use of +P ammo. The ejection problems were largely due to the placement of the rear wall of the ejection port... and its composition (plastic). Rounds hit it on the way out of the port. After a few hundred or so, it would wear a small indentation in the wall which caused the ejected case to be bounced back inside the port instead of flung free. The fix for this on older guns is a small metal clip that goes over the rear wall. Newer guns have had the position of the wall moved back about a half inch from the rear of the opening which obviates the need for the clip. The feed problems... are almost ALWAYS a result of a cheap or defective magazine.

It's your mag!
It's not bringing the rounds up fast enough to feed properly.
Replacement mag springs are available from Wolff...

Wondering if you could give me more specifics about the Wolfe reference like the web site if possible. Thanks
