GLOCK match; what is allowed in production?

[max it]

HI Ya All, So I have shot lots of Glock Mat ches with my model 21. now i want to shoot 9mm. what is allowed; for example I bought a connector usually used for model 34/35 which is a couple of lbs lighter than 21. what else can i put in a model 17/19/34 and still be production?
much obliged, Max

Are you asking about regulation GSSF Stock division?
As I recall Stock Glock will admit a Minus connector, polish of other standard working parts, and open sights that fit the factory cuts. I like fibre optic and am coming around to fibre front and rear.

You may apply grip tape, I really like the Talon rubber. You may not stipple or mold the butt.

You could put the G34's taller magazine catch and longer slide stop lever on a G17 but since you do not reload on the clock in GSSF, there is not much to be gained.


If you are talking about Production division in USPSA, rules are different.

Jim, right on. It's Glock only match's. And you nailed it. TY

Here are the full rules.

https://glock.stylelabs.cloud/api/pu...d35?v=ca8eca66


Here's the section on Stock models, including allowable and prohibited mods. I don't see anything prohibiting a GLOCK minus connector. Note that an aftermarket minus connector would not be allowed.

40.20 Stock GLOCK Definition. For the Amateur-Civilian, Amateur-Guardian, Amateur or MasterSubcompact, Amateur or Master-Heavy Metal, Amateur or Master-Competition, Amateur or MasterMajor Subcompact, Amateur and Master-Master Stock, Amateur or Master Pocket GLOCK, Amateur or Master Rimfire, Amateur or Master GLOCK MOS and Amateur or Master GLOCK Girl Divisions:

GLOCK FIREARMS ARE CONSIDERED TO BE “STOCK” IF ALL FIREARM COMPONENTS ARE OR
EVER HAVE BEEN AVAILABLE FROM GLOCK, INC. EXCEPT AS OTHERWISE SPECIFICALLY
PROVIDED BELOW.

If any component is not or has never been available from GLOCK, Inc. or if the firearm has been
physically modified except as otherwise specifically noted below, it is not “stock” and is therefore
restricted to use in the Amateur or Master-Unlimited division only.

40.30 Allowable Modifications to “Stock”
1. “Hogue Grip”-type sleeves, “A-Grip” panels, “skateboard tape” or other non-permanent gripenhancing materials that do not materially alter the function of the stock firearm
2. Slide and barrel stripping and/or refinishing
3. Pearce Grip, Inc. grip extenders only on G26, G27, G29, G30, G33, G36, G39, G42 and G43
magazines
4. Aftermarket replacement non-metallic base plates on magazines
5. Notch and Post sights (“patridge” sights) excluding any sight requiring slide modifications. Please note that fiber-optic and “express” sights are approved.
6. Aftermarket “Beavertail” grip extensions for Pre-GLOCK Gen 4/Gen 5 (Gen 3 & prior) models that are similar in dimensions, appearance and function to those now available for certain GLOCK Gen 4 and later generation models. Necessary usage of permanent adhesives to affix such Beavertail units is permitted.
7. Aftermarket “Magazine Funnels” made from polymers or aluminum only. Such Magazine Funnels made from Brass or other heavier metals may only be used in the “Unlimited” Division.
8. Installation of the GLOCK Performance Trigger in the G19 Gen4/5/MOS, G17 Gen4/5/MOS, G19X/MOS, G22 Gen4/5, G23 Gen4/5, G26 Gen4/5, G27 Gen4/5, G34 Gen4/5/MOS, G35 Gen4/5, G44, G45 MOS, G47 MOS and G49 MOS only.
9. The installation and use of a functional rail light in the Guardian Division only.
10. A milled, otherwise stock, GLOCK slide to accommodate the use of an optical sight in the MOS, Unlimited and Guardian Divisions only.

You may use any combination of GLOCK-produced firearms parts that do not result in a significant competitive advantage in the Stock divisions and that are, in the sole opinion of the match armorer, safe to utilize.

40.40 Specific Non-Compliant Modifications in the “Stock” Divisions:
1. Any non-notch and post sight. This includes “Ghost Ring” or laser, electronic and optical sights. Please note that fiber-optic and express sights are permitted.
2. Wrap-around “magazine sleeves” on magazines.
3. Aftermarket component parts to be used in the Amateur-Civilian, Amateur-Guardian, Amateur or Master Subcompact, Amateur or Master Heavy Metal, Amateur and Master Master-Stock, Amateur or Master Competition, Amateur or Master Pocket GLOCKs, Amateur or Master Major Subcompact, Amateur or Master Rimfire, Amateur or Master GLOCK MOS and Amateur or Master GLOCK Girl divisions except as otherwise provided for in Section 40.30.
4. Aftermarket barrels.
5. Aftermarket recoil spring guide/recoil reducer assemblies.
6. Firing pins (modified/aftermarket).
7. Connectors (modified/aftermarket).
8. Non-Polymer or non-Aluminum metallic magazine well “funnels” or “”grip filling slugs” of any
kind.
9. Lights (functional lights may be used in the Guardian/Unlimited Divisions Only) or other barrel
weights including GLOCK-produced light/laser units.
10. Aftermarket frames.
11. Any modification deemed by the Range Master to create an unfair competitive advantage
12. Non-factory “stippling”.(Stippling that is burned or cut into the polymer frame)
13. Grip enhancing materials affixed by permanent means, such as epoxy glues, which constitute a permanent modification to the firearm.
14. A “Binary” trigger in which the firearm fires one round when the trigger is pulled to the rear and one round when the trigger returns to reset.
15. Suppressor/Silencer

40.50 All firearms are subject to inspection at the matches for appropriate classification. Random inspections may occur at GSSF® matches. If a GLOCK pistol is deemed illegal for a Stock division, if
possible the competitor’s entry will be moved to the Amateur or Master Unlimited division.
Refunds will not be given to those who fail inspection.

For whatever it is worth, I have shot in a number of GSSF outdoor matches, in four different venues in two different states and have never seen a gun examined by a GSSF match official to see if internal parts are in conformance with the rules.
