Hennig Posted May 20, 2016 Share Posted May 20, 2016 Hey fellas, I have been shooting my 9mm TS for a while now, love it. I recently bought a used .357Sig TS, and am having a bear of a time getting it to feed (nosediving etc). The mags it come with are marked 9mm/.40 on the basepad, and have a different follower to my newer 9mm mags. The 9/40 mags nosedive with more than 8 rounds in them. The newer 9mm mags can only fit 7 in there (being capped to 10 rounds of 9mm, thanks Australia). The most success Ive had is using the newer 9mm follower and spring in the uncapped 9/40 mag bodies. Now, to the crux of my post. I contacted the Australian CZ importer (where the .357 came from originally..), and asked whether the dedicated .40 mags would solve my problems. These guys sell converted .357 TS's, so should know for sure. I couldn't get a straight answer; just that more .40 mags would be in stock in X weeks. Anyway, I was wondering if anyone could tell me if there are any follower/mag lips/spring differences between the dedicated .40 mags, and the two types I have already. Id hate to drop $400AUD on new mags and have it not solve the problem. See pics below: Newer 9mm mag on left, older 9/.40 mag on right in all of the following images. Fingers crossed you guys can give me some advice and that new mags are all I need! Link to comment Share on other sites More sharing options...
Matt1 Posted May 20, 2016 Share Posted May 20, 2016 Do you need to run 10 round mags where you live or can you have standard cap mags? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Hennig Posted May 20, 2016 Author Share Posted May 20, 2016 10 rounders only. They do a dedicated 10rnd 40 mag, which is what Im looking to buy. Link to comment Share on other sites More sharing options...
kneelingatlas Posted May 20, 2016 Share Posted May 20, 2016 (edited) The 9/40 on the base pad just means the base pad can be used for 9 or 40, your picture shows two 9mm tubes, the 40 mags don't have ribs. The 10 round 40 mag looks like this:Full cap looks like this:Running .357 Sig in a .40 mag should solve all your problems.

Hennig Posted May 20, 2016 Author Share Posted May 20, 2016 Awesome, that's exactly what I wanted to hear. I was sure that would be the case, but wanted to hear it from some that are smarter than me before I pulled the trigger (so to speak). Obviously the mags that the previous owner was using with the gun didnt make their way to me... Thanks fellas! Link to comment Share on other sites More sharing options...
MrPostman Posted May 20, 2016 Share Posted May 20, 2016 Yep .40 mags are the cure. The .357 sig is basically a necked down .40 so it can accept a 9mm bullet. Link to comment Share on other sites More sharing options...
Hennig Posted May 20, 2016 Author Share Posted May 20, 2016 Yep! I've been running .357Sig in a P320 for a while now, love the cartridge (especially over here where we cant really have .40 and larger). I guess I figured that since he sold the gun with 4 mags that they were the right ones for the job (hence my confusion trying to figure this out). Mystery solved - its always the simple things that get you! Link to comment Share on other sites More sharing options...

Matt1 Posted May 26, 2016 Share Posted May 26, 2016 I haven't had any problems with them in my TS but did have a problem with some mags in my TS Orange. To fix I opened up the frame just inside the magwell with a dremel. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...

Are blocked free state mags not an option? That is what i use to get away from the 9mm factory 10 rounders for my TS and 75's.

kneelingatlas Posted June 1, 2016 Share Posted June 1, 2016 Not understanding what you mean "free state" mags, Some people in states with magazine capacity laws permanently block standard capacity mags which tend to function better/utilize aftermarket base pads.
