P220 - 10 round mag reliability

[FlyingPen]

My friend with a P220 Combat has found that his 10 round mags he bought a few years ago and finally used have had multiple FTFs.

Has anyone else noticed this problem with these mags? They're all original Sigs, the 8 rounders work fine.

Mine works fine with all ammo through my P220 Combat.

I haven't had any problems with the 10 round magazine on the stainless steel P220. Regardless of FMJ or JHP type ammo.

Same here never had any problems

Ok thanks, it seems the 10 rounders had a design change in the more recent versions...

The problem with the 10 round magazine is that they are barely long enough to fit 10 rounds in them so there is a lot of stress on the feedlips from the spring. Normally that doesn't really affect anything unless you are trying to insert a fully loaded mag while there is a round in the chamber. This could cause enough tension to prevent the slide from cycling properly.

I would try leaving them fully loaded for at least a week to help the springs set.

My Sig 10 round magazine works great. My pro mag 10 round magazine was junk right out of the bag.

No problem with my 10 rounders.
