does anyone know if DPM recoil reduction systems are legal in production division now? Rules say Aftermarket springs and trigger assemblies are permitted. Does that include the DPM system? It's not a spring its a system with 3 springs
 
Since the OP seems to have his answer I don't feel too guilty derailing the thread. Do those things actually work/make a difference? I don't know anyone who has one.

Seems to be pretty mixed reviews on them. Some say that they do nothing and are a waste of money, others swear by them.

I replaced a guide rod (steel for plastic) in a CZ in .40 and it made a difference. Maybe it's just the extra weight that is making the difference?
 
Well they just allowed this system to be used at the European Championships that were just held. There was quite the discussion about it on Facebook. It was used by a Canadian competitor in a Beretta.

Considering Glock uses a very similar setup I would say they definitely do make a difference over standard single spring setups. I have also used one in a CZ75 Shadow 1 in 9mm as well as a Jericho in 40S&W and both made a noticeable difference.

There are officially only three Canadians at the EHC; two that shoot CZs in Prod and one that shoots Tanfoglio in Standard, so I’m a bit confused by this.
If the International Body has changed their ruling, it needs to be confirmed and then word can be spread here.
Any chance you have a name? Thanks.

I think it depends on the gun/ammo combination. In my Tanfoglio Limited Custom .40s&w I'm already shooting very soft recoiling hand loaded 220gr 800fps ammo and I have a thumb rest so I didn't perceive any difference. But in my M&P using factory 124gr 1150fps ammo, yes I notice it just doesn't feel like the slide is slapping into the frame as hard when it cycles. But that also tells me that it's just one poorly loaded round away from a short cycle and a failure to feed.

I put thousands of rounds through 2 different DPM equipped guns and don't think I ever had a short cycle/failure to feed(if there were there were so few I can't remember lol). Unless you plan to shoot low PF rounds to try and get an unfair advantage, I wouldn't worry.

He has a youtube channel called Shooter's Inc, and his first name is John. I'm sure you can figure out his last name Sean.
 
Yes John used a borrowed a Beretta 92x from Beretta and it had a DPM setup in it and it was known to IROA during equipment check and throughout the match.
One weird one was the Toni systems grips being denied for Production on a Shadow 2.

Thanks Rob. I've emailed John for details, and will contact IROA for info. They told me last year that DPMs were no-gos. If they've reversed that decision; they didn't bother to let the regions know. I don't care one way or the other, we just need to know.

I wouldn't be surprised if they reversed from EHC lol

I have confirmed with IROA and the IPSC Executive that the DPM remains prohibited from use in the Production divisions guns.
At the EHC, they say something must have happened for this to slip by and our competitor got lucky. They'll be more diligent in the future.

There is a chance that the DPM may get approved later on; and they assure us that they will let us know if things change.
