gunner40sw Posted May 18, 2009 Share Posted May 18, 2009 Just wondering how often do they check the length of the mags on limited shooters at matches? Link to comment Share on other sites More sharing options...
chirpy Posted May 18, 2009 Share Posted May 18, 2009 Depends...I have never had mine checked anywhere. That is just me. FWIW Richard PS: Been to 2 Nationals and several other bigger matches. Link to comment Share on other sites More sharing options...

Gregory_k Posted May 19, 2009 Share Posted May 19, 2009 Summer blast, I would see ro's checking your ejected magazines, most shooters never noticed that the mags were checked as they were watching the other RO call hits. Link to comment Share on other sites More sharing options...
ChuckS Posted May 19, 2009 Share Posted May 19, 2009 They checked mags at last year's Area 2. Link to comment Share on other sites More sharing options...

gunner40sw Posted May 19, 2009 Author Share Posted May 19, 2009 So a SV 140mm mag with a Dawson snl would not pass probably. So if they are checked and they are to long what does that change. Are you moved to open? Link to comment Share on other sites More sharing options...
Kingman Posted May 19, 2009 Share Posted May 19, 2009 Moved to open, if over 170 shooting for fun. I have seen it a good bit around this area. Link to comment Share on other sites More sharing options...
Flexmoney Posted May 19, 2009 Share Posted May 19, 2009 Sounds like...if you weren't going to get caught, you'd use a mag that was against the rules ? Link to comment Share on other sites More sharing options...
Joe4d Posted May 19, 2009 Share Posted May 19, 2009 Why does it matter if your going to get checked ? They should be legal any ways. Link to comment Share on other sites More sharing options...

Are you moved to open? Most SV 140 mags with an SNL will not fit the gauge without a little tweaking. Doesn't take much, but without a little working I have yet to see one that would fit. I wish they got checked more often, would make this EGW gauge worth the change spent on it. Link to comment Share on other sites More sharing options...

kgunz11 Posted May 19, 2009 Share Posted May 19, 2009 I sure hope it's measured empty, I don't have a mag that will fit loaded. Link to comment Share on other sites More sharing options...
persona non grata Posted May 19, 2009 Share Posted May 19, 2009 where does one get this gauge? Link to comment Share on other sites More sharing options...
ChuckS Posted May 19, 2009 Share Posted May 19, 2009 This is the measurement: It would be kind of hard to do that measurement with a round in the mag you can get the gauge here Later, Chuck Link to comment Share on other sites More sharing options...
persona non grata Posted May 19, 2009 Share Posted May 19, 2009 $35 for a gauge, sounds like the making of one of those mastercard commercials. The look on a competitor's face when his mag doesn't fit the gauge....priceless.... thanks chuck! Link to comment Share on other sites More sharing options...
jasmap Posted May 19, 2009 Share Posted May 19, 2009 Moved to open, if over 170 shooting for fun. I have seen it a good bit around this area. The rule may have changed but 170mm wasn't the max for Open before. It was 171.25 or 171.5 I believe. Has this changed? Link to comment Share on other sites More sharing options...
Carl Provan Posted May 19, 2009 Share Posted May 19, 2009 Moved to open, if over 170 shooting for fun. I have seen it a good bit around this area. The rule may have changed but 170mm wasn't the max for Open before. It was 171.25 or 171.5 I believe. Has this changed? The mag gauge made by EGW is made to 171.25 (I think) so USPSA has made that the official guage and thus the offficial length. I have not seen a mag get shorter if it is empty rathar than loaded. The measurement is the the top of the mag not the round that is in it. That round will compress down into the mag while being checked. I have one of the EGW gauges and use it for the Level III matches that I host. I think I am hosting The Infiinity Area 5 Championship this year? Carl And I believe that a SS/Prod box will be on site.

TeamGE Posted May 19, 2009 Share Posted May 19, 2009 Years ago, EGW was asked by USPSA to make an official "mag length gauge", and was told to make sure that all the combinations of tubes and base pads that were available at the time would fit this gauge. It was deemed necessary to make the gauge measure 171.25mm and 141.25mm, to allow for all the manufactures parts to be legal. As a manufacture, I received my official gauge, and because of this increase in length (1.5mm) over previous rules, I proceeded to make a longer base pad (4mm) to make it possible to fit the gauge exactly, compared to my 2.5mm pad. An exact fit to the gauge is worth some room inside the mag, but now you have to check the length with the combination of parts you choose. Once this gauge was used officially, the rule book was eventually changed to match what the gauge measured. Link to comment Share on other sites More sharing options...
larry cazes Posted May 19, 2009 Share Posted May 19, 2009 If you do get checked and your mag fails, ask to see how the gauge is being used. There is very little margin for most of the common setups and it is easy to mistakenly fail perfectly good mags if you dont have experience using the gauge. Ask me how I know? I once disputed a call and it was overturned later on for this very issue. Link to comment Share on other sites More sharing options...
gunner40sw Posted May 20, 2009 Author Share Posted May 20, 2009 (edited) Not at all flex i am just getting new tubes and base pads and I just want to know what will work. So let me ask if I use a new SV 140 mm tube with a dawson base pad should that fit in the gauge? And what kind of spring and follower combos are people using and how many reloadable rounds can I expect.
