On all my 5" 1911's I use an STI Recoil Master and love it. STI ships it with all their gins so it is not a gimmick.

DPM also has a recoil reduction system for almost all other handguns and I was wondering if anyone has tried them.

For those not familiar it works similar to he double springs you see in a small handgun and also usually makes it easier to rack.

DPM is a Greek company, with zero customer service. I don’t think their system does anything for recoil: multi- spring assemblies divide recoil between springs, but can’t change physics. Newton still rules the day.

The DPM system uses springs that look suspiciously like they came from a European hardware store. When corresponding with the owner (DPM appears to be one guy), he seemed surprised that I’d be interested in buying spare springs, or various weights of springs as spares. He seemed suspicious, too, like perhaps I might be trying to make my own reduced recoil system, or steal his secrets.

I bought a kit from a member here, who had no luck getting any information from DPM. I did get through to the owner, but he’s very tight with his information, and I can’t say given the source and the materials that I have much confidence in the system. I bought it for a P320 compact with the idea of having spring options to tune for a given bullet weight and load, but the DPM system really doesn’t do that. It does over several combinations of springs for something like six possible weights, but gives no indication as to what they might be. The springs, construction and material, do not look to me like they’d hold up for long. The owner seemed surprised that I’d replace the springs with any regularity: he seemed to feel that his product was a lifetime arrangement, the insinuation being that nobody would ever shoot a pistol enough to require new springs. I don’t have confidence that the DPM springs would last long.

Nor is that an accurate statement. Their guns either.

Recoil reduction devices have been discussed here a good number of times over the years. I think Bruce Gray even provided input.
They are only gimmicks. As said, Physics rules.

Sprinco, of Austin, TX also makes recoil reduction systems for those interested. They also offer replacement springs for these systems.

I have 2 of the DPM systems, used in my Walther PPS 9mm and 40's. And have a DPM system in my Glock 22.

I had a couple on my 2011s in 40S&W. They do "tame" the snappy .40 (for want of a better word). However, the manufacturer claims that the main recoil spring never needs to be changed. This is nonsense, especially if your gun gets toasty and cooks the spring in intense sessions.

I switched back to normal 12 or 13lb springs and am happy. let the .40 "snap" to it's heart's content.

For 9mm, I wouldn't consider them for a second.

I once tried to get help with STI customer service. Made the DMV feel like family.

They have a lock on don't give a fuckery.

Bastards.
