IPSC and USPSA rules are independent of each other. If it is allowed in USPSA, it is not necessarily allowed in IPSC. In USPSA, you can have a thumbrest in a production or CO gun if it is "built in" to another existing part, such as the slide stop. In IPSC Production, the default position is that you can only use parts that are available from the original manufacturer. The rules then state the aftermarket parts that are allowed (such as sights, magazines, triggers, springs). It gets a bit complicated because a gun manufacturer could indeed manufacture a part that incorporates a thumbrest. And there is nothing in the Production rules that explicitly forbid a thumbrest. But it seems that, based on the response you got from IPSC, that thumbrests will not be accepted in Production, even if they are offered as a part by the original manufacturer of a gun that is on the Production list.

At the European championships last year, at equipment check they weighed my basepads. They then asked if I had any factory basepads to compare to. I said no. They had a short discussion and then just approved my gear.

IPSC are moving towards demonstrating the start position, to try and remove any way of "gaming" it. They will even sometimes enforce the direction your head is facing (so no looking to the side to your first shooting position while waiting for the beep)

I use the Scalarworks LEAP mount (with the Trijicon RMR/SRO footprint)

Yes, at least one batch was withdrawn because of either light strikes or squibs.

I think a large window is more forgiving if your index is not perfect and you find yourself needing to 'search' for the dot.

I have heard that the quality of Geco Hexagon has gone downhill since 2023, as a result many of the german PPC (1500) shooters have stopped using it.

Is this a byproduct of strange follower/spring setups to maximise capacity in a mag?

Thanks, this sounds like the sensible approach

I currently shoot IPSC Production, so there are no restrictions on magazine size, just how many you can have loaded. I'll be getting a Standard (ie. Limited) gun soon so wanted some advice on whether people load their magazines to full capacity. A fully loaded magazine is usually harder to seat on a closed slide, so do people get around this by down-loading the mag by a round?

L2 need to be sanctioned by your local IPSC region, so it's up to them what criteria they set. L3+ need to be sanctioned by IPSC.

I really wonder why USPSA Production has seen such a decline, yet is still the largest division by far in IPSC (going by EHC 2023 figures)

To get the trigger unit out

I owned one, the lack of a manual brightness adjustment was a dealbreaker. Managed to sell it on at not much of a loss.

Gravity acts on the gun in the same way regardless of which hand is holding it and what direction you're shooting. Shooting inwards makes sense because the recoil of the gun carries it in the direction of the next target.

Right hand - go right to left because the recoil is naturally going to carry the gun to the left. But as IVC said, this is not a hard and fast rule ultimately you should shoot the target order that makes the most sense. Same idea as "never leave a position on a steel"

Can anyone explain how to remove the ejector from the JP-5? It's probably very simple but I don't want to do anything to try and figure it out for myself (and potentially mess up) before asking

On an AR the hammer will fall even when the bolt is out of battery. This is how you decock a 22lr AR-15 without 'dry firing' it.

I'm not sure if IPSC contributes anything to the individual regions. I don't even think they pay for the RDs to fly out to the general assemblies. What the individual member regions do is their own business, and it could well be that the leadership of some of those regions are enriching themselves. In that sense, it would be no difference to the accusations of malpractice going on in USPSA, which itself is just another member region of IPSC.

That's a very long cartridge

It's going into a JP modular trigger unit so I assume the hammer is already a light version.

Thanks, I will give those springs a try

Yes I figured the same. I ordered a pack of competition springs that contains reduced power versions of all three springs. They claim it can bring the pull weight of a factory AR trigger and hammer down to 2.5lb

Did you have to re-adjust the micrometer setting after removing the spring?

I have an 8" barrel and run the 70 on it. I know that a short barrel length should mean less pressure (and therefore a higher lock piece needed) but certainly not to the extent that you need to go to a 90 or 100. Why do you want to run such high lock pieces?
