Shorter 170mm mags

[mikeg1005]

I am just getting into open, but know the 2011 pistol.

I got some used 170mm tubes... they are older ones. I just stood it next to a new 170mm tube and it is 5-6mm shorter.

Anyone info about these mags? I played around with it...and it holds one round less than the full size 170mm. I could imagine with a long basepad there is potential to for more a good amount more capacity.

Any thoughts? Info?

Thanks,

Mike.

Im not super in-the-know on this topic, I feel like someone used to make a 164-ish mm tube and that was the reason for 7mm basepads...

It's a 164mm. Use to own one. I like it though. I kinda regret selling mine. You can use 7mm pad on that one. It's quite reliable too.

Just go to a longer pad. I think Grams makes one for it.

I think Taran Tac has a 7mm as well.

Thanks for the replies.

So 7mm pads. What about the 8mm I see that grams makes? Or is that a borderline thing like a +1 and SNL pad?

Thanks,

Mike.

I have an SV 164mm with a Grams 7mm pad, spring and follower. Holds 29, un-tuned. It is an old tube, has a funky grey unpolished finish.

2nd the Grams 7mm pad, although I would just sent it Beven and have it tuned.

I have one of the 164 and some shorter ones too, they were something like 133 or 134. If they are the SV and a dull dark gray, those sound like the ones I have. I am pretty sure those are the original ones I purchased before the '94 AWB.

OPENB, when did you buy your mags?

[OPENB]

The grey SV I got with the gun second hand. I've had it 10 years, and the original owner probably had it 5 years before that. The rest of my SV mags are the shiny stainless steel. I got lucky, when I bought my open gun, SV mags were common. So when I rebarreled it to 9mm, I already had 8 mags that I did not have to modifiy. The one STI mag I have a spacer in, but it works great.

Yes, my tubes are also that unpolished look but I'm pretty sure they are STI ones... they have the two ribs on each side instead of the wide reccess like most SV mags have.

For the indoor club matches I only use STI mags with no spacers - don't want to drop the SV mags on concrete... So far no single failure in those mags with no spacers.

Same here. The "old" STI double ribbed ones get dropped for the indoor matches. We try and keep the mandatory reloads to a single position and put a large piece of carpet on the floor. Some of the shooters still miss it and the mags end up hitting the concrete feed lips first .

I use the SV everywhere. Can't remember having to reload after shooting a big stick on an indoor stage. We usually shoot 3 strings of 24-27 rounds each for our Monday night league, or a shorter course for the indoor stage at the monthly match.

Courses typically are not long, but often require mandatory reloads.
