IDPA Pistol Requirements: Stock Service Pistol

This is the second in a series of blog posts helping competitors answer the question: “Is my pistol IDPA legal?”

This division was created, as the name implies, for stock pistols that are straight out of the box with minimal investment to compete in IDPA matches. The requirements are:

  • An IDPA-legal pistol must have a minimum production number of 2,000 per year or, if no longer made, the manufacturer must have made at least 20,000 of that model.
  • The pistol must be a semi-automatic that is double action, double action only or striker fired that fires a 9x19mm Luger/Parabellum cartridge or larger.
  • The pistol cannot weigh more than 43 oz. (2 lbs. 11 oz.) with the heaviest magazine inserted in the empty pistol. Most pistols weigh below this, but make sure you put it on at least a home postal scale to confirm it. You would not want to show up at a sanctioned match with a heavy pistol after you have spent the time and money for travel expenses.

Since the restrictions are out of the way, let us see what can be done to the pistol. These are the permitted modifications (or inclusive) list:

  • Sights may be changed to another notch-and-post type. Slides may not be machined to accept different style sights. (Ghost ring type sights are not allowed. Or to recut the slide for a new type of sight other than what came from the factory.)
  • Grips may be changed to another style or material that is similar to factory configuration and do not weigh more than 2.00 oz. than the factory standard weight for that model.
  • Magazine releases, slide stops, safety levers, de-cocking levers, hammers, and triggers, that are stock on one SSP legal firearm may be used on another SSP legal firearm from the same manufacturer provided they are drop in replacements. Parts in this list must be factory installed on a standard production firearm or firearms. Special parts that are available installed only from a factory custom shop are not eligible in SSP. (You can mix and match different parts off of different models of pistols.)
  • Recoil spring guide rods and dual spring recoil systems made of material that is no heavier than stainless steel.
  • Frames may be replaced with identical frames from the same manufacturer. (Meaning a Glock 17 frame can be replaced with a G34 frame and the like).
  • A slip-on grip sock and/or grip tape, skateboard tape, etc. may be used.
  • Internal action work may be used to enhance trigger pull as long as safety is maintained (no visible external modifications allowed). Internal reliability work. (This is polishing or replacing internal components that are not visible unless you field strip the pistol.)
  • Aftermarket extractors and pins may be used.
  • Internal accuracy work.
  • Replacement of barrel with one of factory configuration that uses the original cartridge. (Yes, you can put an aftermarket barrel in your pistol, if it is the same original caliber.)
  • Plastic plugs may be used to fill the opening behind the magazine well.
  • Custom finishes may be applied. Stock slide cover plates may be refinished. Slides may be engraved. Engraving is defined as etching into the slide of logos, letters, and graphics no deeper than the original factory logos.
  • Stippling and texturing may be performed on readily replaceable parts of the grip frame such as replaceable back straps and replaceable grip panels.
  • Aftermarket magazines may be used provided they do not weigh more than 1 oz. over the same capacity factory magazine. Aftermarket magazine base pads may be used provided they do not make the magazine weight more than 1 oz. over the same capacity factory magazine. Magazine base pads may be modified by reshaping, texturing, or adding bumper pads provided that they do not make the magazine weigh more than 1 oz. over the same capacity factory magazine. Magazines that are longer than stock may be used provided they meet all other division requirements.

Stock Service Pistol Division (SSP) has its own additional restrictions which are called Excluded Modifications. These include but are not limited to:

  • Externally visible modifications other than those listed in the Permitted Modifications section.
  • Aftermarket or visibly modified magazine releases, slide stops, safety levers, de-cocking levers, and hammers.
  • Robar-style grip reduction.
  • Add-on magazine well opening.
  • Slide inserts to accommodate a different recoil assembly design.
  • A barrel that uses a different cartridge that is not offered in the original factory model.
  • Customization of the slide by adding front cocking serrations, tri-top, carry melts, and high power cuts.
  • Compensated/ported firearms with non-compensated/ported barrels installed.
  • Checkering or stippling on non-readily replaceable parts of the grip frame.
  • Aftermarket slides.
  • Removing material from the magazine well opening.
  • Aftermarket grip tang extensions or beavertails.
  • Disabling the slide stop

This post is not intended to replace the IDPA Rule Book, but is simply a guide to help the interested shooter become more familiar with the pistol rules. All competitors are responsible for reading, understanding and following all IDPA rules. If you have any further questions about your pistol, please feel free to call or email your local IDPA club contact, Chief Safety Officer, Match Director or Area Coordinator to help you with answers to your questions. We have the knowledge and ability to guide you through the rule book so you will have a fun experience with the sport and want to continue to further your shooting abilities.
