FAQ’s

Q: What is the warranty on STI products?

A: We unconditionally warranty our products for their intended purpose when installed properly. As with any product, abuse and normal wear are excluded. We stand behind our products and if you EVER have a problem with an STI, we are going to make sure to take good care of you! We pride ourselves on having the best Customer service anywhere (since we have the best Customers anywhere…) The STI warranty covers the product- not the original purchaser so even if you purchase it used, we will still warranty our work. (We do not warranty other people’s work, though, so if you or anyone else works on the gun it might void the warranty. Contact our warranty department and they will handle it on a case by case basis.) Be sure to contact the Warranty department for an RMA before shipping any warranty items to us. Any packages without a clearly marked RMA on the box will be rejected.

Q: Are STI pistols made in America?

A: The Spartans are built for STI (to STI specifications and utilizing STI internals) in the Philippines. The Spartan has been discontinued and all current STI models are assembled and hand fit right here in Georgetown TX with the best parts available from around the world.

Q: Are the aluminum grips covered by STI’s warranty?

A: The aluminum grips are covered by the same warranty as all the rest of our parts- we unconditionally warranty our products for their intended purpose when installed properly. As with any product, abuse and normal wear are excluded.

Q: Why should I use the new, caliber specific, magazine follower instead of the old style that came in my original magazines?

A: the original STI magazine follower was designed about 1992 for “IPSC” and “Steel Challenge” shooters who were using .38 Super and 9mm ammunition, and who preferred that their slide not lock back when empty.
Now that we build so many more calibers for so many more purposes, we found it necessary to produce followers in a more “main stream” manner to accomplish a couple of things. These followers should cause your slide to lock back when the magazine is empty and, due to the new cant direction, not before. AND because they ARE caliber specific, they are less likely to turn over sideways in .40 and .45 caliber magazines.

Q: What’s the status of .40 Super .450 SMC chambered guns?

A: We are suspending production of firearms in .40 Super and .450 SMC until a commercial ammunition source becomes available.

Q: Where can I find some load data for my STI?

A: Try Jeff Maass’ IPSC Resources Page Please note this is a community supported web site and Jeff requests that people send loads with powders only available in your area.

Q: I do not reload but want to shoot major power loads in your pistols. Where can I purchase 9mm and .38 Super major loaded ammunition?

A: Atlanta Arms & Ammo. produces high quality ammunition for use in competition pistols. They can be contacted at: Atlanta Arms & Ammo. 721 Vine Cr. Social Circle, GA 30025 Phone:770-464-2203 or by visiting their webpage at: AtlantaArmsAndAmmo.com

Q: Can I use factory ammunition with my TruBor, MatchMaster, SteelMaster, or TruborGM?

A: The STI TruBor, TruBorGM, and MatchMaster are designed and tuned for IPSC Major Power Factor grade ammunition. Factory .38 Super and .38 Super +P generally do not meet the minimum power and pressure levels required for proper operation of these competition grade firearms. The SteelMaster, however, was specifically designed to run factory ammo.

Q: What can I expect the trigger pull weight to be on an STI handgun?

A: About 3.5 lbs- 4lbs on the competition models, 4-5 lbs. on the others.

Q: What is the difference between a STI and a SV gun?

A: It is much easier to answer the question, “Comparing the STI gun to the SV gun, is anything the same?” The answer here is, “Certainly. The frames are built by each company under a shared patent.” Past that, it would be the same as trying to compare a 1911 Colt to a 1911 Springfield to a 1911 Kimber to a 1911 Norinco, or any other 1911 clone. Different manufacturing facilities, different people, different processes, different checks and quality standards.

Q: Can I install a SV left handed grip on my STI frame?

A: There is nothing that we know of that would prevent this from working. Though, if we understand correctly, this conversion would also require SV “left handed” magazines.

Q: Will SV magazines work in my STI gun?

A: In short, some will and some won’t. We are given to understand that the SV mag release is located a little higher than the STI. From our experience on the range, however, we have seen some mag swapping in both directions.

Q: What makes the STI “TruBor” barrel and compensator superior to a “screw on”, or anybody else’s compensator system?

A: While independent tests conducted in Switzerland have proven that the S-2 and S-1 (STI’s discontinued screw on compensators) are the equal or superior of every other compensator on the market, the TruBor has several characteristics that make it yet more superior. This unit, which comes in a .355″ bore diameter only, is fabricated from a single piece of 416R (rifle grade) stainless steel and, therefore, has no need of threads nor the area that the threads would occupy. This allows it to be .400″ shorter and approximately 1½ oz. lighter. Since there are NO threads, it is legal in California, cannot come loose, is a great deal easier for a gunsmith to fit and “clock in”, and is inherently more accurate. To explain further, since the compensator is both bored and rifled at the same time and with the same tooling as the barrel, there can be no misalignment. Because the alignment is perfect, the clearance bore in the compensator can be tighter, and therefore more uniform than is possible in a threaded compensator. With gas pressures equal on all side of the bullet, enhanced accuracy is a given.

Q: What is the recoil spring weight in my gun?

A:

  • Compensated pistols 8 pounds
  • 5″ 9mm guns 10 pounds
  • 5″ .40 S&W guns 14 pounds
  • 5″ .45 ACP guns 18 pounds
  • 6″ 9mm guns 8 pounds
  • 6″ .40 S&W guns 12 pounds
  • 6″ .45 ACP guns 14 pounds
Q: Will my full sized 2011 magazines fit in the smaller guns like the “V.I.P” or the “Total Eclipse”?

A: Yes! They’ll just hang out a ways.

Q: What is the dimension of the dovetail cut for your front sight?

A: All our front sights are .300″ X .060″ X 60 degrees.

Q: What is your front sight blade width?

A: The competition width is .110″ while the carry width is .120″.

Q: Will STI 2011 mags hold any ammunition loaded longer than SAAMI spec of a specific caliber?

A: YES, but the .38 Super and 10mm versions will not accept ammo longer than 1.250″.

Q: How many rounds do STI double stack magazines hold?

A: It really depends on the phase of the moon and the strength of your thumb, but the following guide lines are reasonably accurate: (You may get one more.)

  • 126 mm length – (9mm, 38 Super) 17
  • 126 mm length – (40, 10mm) 14
  • 126 mm length – (45, .450) 12
  • 140 mm length – (9 mm, 38 Super) 20
  • 140 mm length – (40, 10mm) 17
  • 140 mm length – (.45, .450) 14
  • 170 mm length – (9mm, 38 Super) 26
  • 170 mm length – (40, 10mm) 22
Q: Will my STI pistol look exactly like the one on the website?

A: While we do try to keep the website and catalog photos as current as possible, there is often a lag between an improvement being implemented and being reflected on our marketing materials. For this reason, all entries are representative only and subject to change without notice.
