Rival S IPSC Setup

[ChrisDeRouen]

Tldr : What magazine base pads, springs and followers do you run for ipsc?

 

I'm converting my gear over to ipsc.  I shot my Rival S from February of last year all the way up until today's match with a USPSA setup.  I ran MBX followers/springs with henning +4 basepads.  I never had any issues over the course of about 8k rounds.

 

Today, I ran canik factory mags.  Of the five stages I shot, I had 3 failures to feed and one failure to extract.  

 

I've never dealt with this before.  No gun internals were changed....just mags.  Help! lol
