I never noticed until recently that my Sigma 40VE Hi-Cap mags (2) rattle.I changed the mag springs 2 weeks ago. Is this the result of not getting that notch in the metal strip that rests on the floor plate on the base of the spring or is it normal. They function fine...just wondering.

Pretty common issue with all S&W mags. Take one round out and the rattle should stop especially if it's a hi-cap mag.

That's good to know, Torrejon224. Thanks.

Yeah it's because they are double stack if you take one out it stops take another out it will rattle again.

Oh. I thought it was the Glock inside trying to get out.

I found hitting the base of the mag on the palm of my hand stops this. Dad calls it settling the Mag.

with my sigma 9v i find that if you take the mag and tap the back of it in the palm of your hand it seats all the rounds and stops all rattling
just my $.02

Ditto. Works every time.
