ichetucknee Posted August 8, 2011 Share Posted August 8, 2011 I'm curious as to what mags STI Trojan 9mm shooters use that have 10 rounds or better. I tried Cobra mags but they wouldn't load the first round reliably. I've heard that 38 super mags work well but I don't have any experience with them.

Victor_R Posted August 8, 2011 Share Posted August 8, 2011 You must be using JHP's? I've been running Tripps and just got some Dawson's as well which I ran today. No problem with FMJ's or CMJ's for me. I haven't tried JHP's in the Dawsons yet. Here is the video from todays match. Link to comment Share on other sites More sharing options...

When you say the first round won't load reliably, can you be more specific? Are you getting nose dives? Depending on the type of issue, that will let the folks on here figure things out a little faster and help you more. The more detail you can provide, the easier it is to find a cause and offer a remedy. Link to comment Share on other sites More sharing options...
DWFAN Posted August 8, 2011 Share Posted August 8, 2011 Metalform and Colt 38 super mags nose dive for me with more than 7 rounds in them. Metalform 10rd Elite and 9rd "Springfield front ramp) mags are the only mags that have fed flawlessly in my 9mm 1911. Locking the slide back is another story. They all need tuned for that. Tripp mags run great with Lead flatpoints and 147gr Montana Gold CMJ's, but for me, wont feed the first or 2nd round reliably with 124gr JHP's.

Braxton1 Posted August 9, 2011 Share Posted August 9, 2011 We've had pretty good success with the Dawsons (if you need 10 rounds). If 9 is enough for ya, The Springfield/Leatham/Metalform mags are pretty good also. Link to comment Share on other sites More sharing options...

If 9 is enough for ya, The Springfield/Leatham/Metalform mags are pretty good also. I have the Dawson 9 round mags. I bought them several years ago when I bought the pistol. They work fine, except for the time when the floor plate fell off during a match and dumped 7 rounds on the ground. Dawson replaced it, no problem. Maybe I should try their 10 rounders.

DT Guy Posted August 9, 2011 Share Posted August 9, 2011 I've been trying to run Tripp 10 rounders in my STI Spartan, and having consistent double-feeds. After calling Tripp and speaking to Virgil himself, he said that some guns require the feed lips closed from .325" to about .310" to avoid letting rounds spill during reloads. I have modded the mags, and will try them later this week to see if they remedy the issue. I have to add that Mr. Tripp was absolutely the most informed, pleasant fellow to speak with. He took the time to describe to me all the challenges involved in getting a 9MM to feed correctly, and before telling me how to do the mods, he flatly stated that there was NO risk for me; he would be ready to replace/refund the magazines at any time. Class act, for sure. Larry Link to comment Share on other sites More sharing options...
DWFAN Posted August 9, 2011 Share Posted August 9, 2011 I would be very interested in hearing how the feed lip modification works out. Report back if you would.. Link to comment Share on other sites More sharing options...

ck1 Posted August 13, 2011 Share Posted August 13, 2011 Not to bum anyone out, but I've yet to see a 9mm 1911 that will really honest-to-goodness load reliably from slide-lock that hasn't had it's feed-ramp re-cut to a shallower angle. I got pretty close to 98%-reliable using Wilson ETM's in a Trojan using FMJ exclusively, but I would still get a nose dive every now and then (usually in a match). In IDPA I started loading 9 instead of 10 and that was a lot more reliable, in USPSA SSTK loading 10 I would put a drop of FP-10 directly on the feed-ramp in the safe area between stages and that worked out fairly well, also load as long as your chamber will allow you to get away with... Seriously, if you have the loot, stop fighting with mags and have Mr. Tripp re-cut your feed-ramp to less-steep more short-OAL-friendly angle like he does for SSTK .40's and it'll run like a Glock... the loading/nose-dive issues come from running a shorter-OAL round in a platform designed for a longer-OAL round, good mags help, but they can't overcome space and time...

40S&W Posted August 13, 2011 Share Posted August 13, 2011 I run Tripp 10 round mags in my 1911 9mm Loaded Springfield with absolutely no problems. I don't run JHPs' because they are a problem in most 1911s'. No problems with FMJ factory ammo or handloads. Running an OAL of 1.142 on reloads. 1.15 OAL or less with factory ammo. Also run the same 9mm handloads in my STI Open for steel plate without any problems. Link to comment Share on other sites More sharing options...

The biggest cost in sending it to Virgil is the shipping - about $150 round trip. But seriously, it's money well spent... Link to comment Share on other sites More sharing options...
40S&W Posted August 14, 2011 Share Posted August 14, 2011 As JDHunz said send it to Vergil Tripp, you won't be sorry. Use your FFL to send the gun & receive it cost is about $80-$90 round trip. Link to comment Share on other sites More sharing options...
Severian Posted August 15, 2011 Share Posted August 15, 2011 I had problems with the Wilson mags, problems with the Tripp mags. I've had zero problems with the Dawson 9mm mags. Love em. Link to comment Share on other sites More sharing options...
