Ruger GSR Polymer mag fail.

Purchased two of the polymer mags for my GSR and they are not doing well. It usually stops feeding after the 7th round or so. Rap it on the bottom and it works. Once the entire bolt jammed though and that was disheartening. I have loaded and cycled over a hundred rounds through them. Failure almost every time. Just thought you guys would want to know. I'll call Ruger on Monday.

Had they been loaded for any length of time? My ten round poly fails if I leave it loaded for several days. The steel magazines and the poly five rounders are 100% no matter what.

Currently I've replaced the spring in the ten rounder with a cut down spring out of a AR15 30 round magazine and so far that's been much better but it now only holds nine rounds.

They were brand new today.
