9mm Trojan Weight

[ogiebb]

Hello,

Im finally getting some projects off the ground and was thinking of getting some SS 9mm's built.

it will be almost the same config as a 9mm trojan w/ a dawson magwell and dawson mags (Flat Top w/ egw fire controls, etc...).

my question is does your 9mm STI trojan w/ the dawson magwell & dawson magazine make weight under uspsa and IDPA rules? the barrel on 9mm 1911's are def heavier than the 40sw and 45's. do i have to get an aluminum guide rod ,change to AL grips or worst case tri top the slide?..thanks

My STI Trojan in 45 w/Dawson magwell & STI mag w/Dawson extension made weight at SS Nationals this year. No further mods. Can't remember exact weight, but it was not an issue.

My old 9mm trojan with a dawson ice made weight with a aluminum guide rod and some heavy grinding on the back of the davidson G10 grips. My new one, I used the aluminum mainspring housing with the no gap ice and the same modified grips made weight with a 1/2 ounce to spare with the steel guide rod. I'll put the aluminum rod in at sanctioned matches to be safe. Weigh the mags also, I've noticed a huge difference between manufacturers. I had to put Chip McCormick mags in my CDP TRP to make weight there. I use Dawson 10 rounders in the 9mm. Hope that helps.

9's are much heavier than 45's due to the extra metal in the barrel.

For IDPA you will not be able to use an Aluminum guide rod. tread rules on allowed modifications.

Good to know Thanks

Just install the GI guide rod and plug.

I believe the aluminum guide rod is legal in esp. Or at least it was when I ran it. I always check to see if I'm legal. This was about two years ago.

I have a spartan 9mm that I am running with unmodified vz grips Dawson arched steel mash magwell and a GI guide rod that makes weight. A steel guide rod is overweight

[Mike21STI]

Where in the new rulebook does it say aluminum guide rods are not permitted?

[Paul-the new guy]

Aluminum guide rod is GTG in IDPA and you will probably need it for the 9mm Trojan, I did. I had a steel MSH and G-10 grips and it was overweight with steel guide rod

My STI Trojan in 9mm, with Dawson no-gap ICE magwell (alum MSH), Dawson 10rd mag with no-gap base, and VZ grips, makes weight by .1 on my basic food scale. I have never had it weighed at a match or tested using a different scale. It is cutting it very close as scales do vary.

Thanks guys.. ive decided to just use a Dawson magwell w/ alum MSH and alum techwell grips ..will see if it makes weight

im not a big fan of GI guide rods so worst case is that i will use an Alum guide rod for USPSA.. and use a diff gun for IDPA

You'll make it with aluminum grips with the steel guide rod. Those G-10 grips are some heavy suckers!!!

You can gain another .5 ounce by grinding out the backs of the grips. I use a postal scale and when it was weighed at the IDPA state match, it was identical in weight.
