Hello everyone, I just found this forum, and I really impressed by all the information I have been reading about. I am a certified 10mm NUT, and have been since 1983!!! I have not owned a 10mm yet till November of last year when I bought a Glock G20 Gen 4. I have replied to a post elsewhere in this forum, and some of the information I am posting here is redundant, but this is important enough that I thought I would pass this on to everyone. This is many months of R&D on my part, and one of those things that TRULY WORK 100% as advertised by the company. It works SOO WELL, that I would call it a GAME CHANGER in the handgun world. This system worked so well, I bought it for my other three guns (semi-auto) as well. You can read below as I posted some of this to a response on "Using Heavy ammo from Underwood in the G20 10mm handgun without damaging the frame, and also reducing the amount of recoil so as to keep on target with your grouping patterns. I am not kidding when I say "It removes at least 30% of the actual recoil out of the Glock G20", and this system is fully adjustable as it comes with several outer springs, and different control rods. If you are tired of changing single springs, and the adapter from Gen 4 to Gen 3 so you can use the stiffer springs, and the stronger steel guide rod, which USED to be the way to go THEN READ ON, It is NO MORE!!! Like one of the other readers on this thread, I used to HATE Glocks, and swore I would NEVER buy one. The only reason I ever got one, is 10mm. I have been a 10mm fan since 1983, and other than getting to shot one in 1989 (Delta Elite Colt), I just never got around to it.
As a mater of fact, shooting and guns had left my life for the better part of 18 years, and I just got back into it last year. The first thing I did was go back to wanting the 10mm and MAN did I ever have a LOT to learn.
Anyway, as I found out the choices for 10mm are NOT MANY, and it seems that Glock was the only company that stuck it out in terms of development with 10mm. After 6 months of Research on the matter, in November of last year, I bought the G20 10mm Gen 4. I am happy with the gun, but like most of you, I DONT WANT A 40 Short and week load in my 10mm. I found out about Underwood, and never looked back.
I have found, through my research, the ANSWER to the recoil problem, that just plain kicks the fire out of Glock store, and all the rest of the solutions offered called DPM Systems. They have the answer PERIOD!!! Go to http://www.dpmsystemsusa.com/ and solve the 10mm problem with the g20. They offer the Heavy Duty kit (I called Dmitri's, the owner of DPM) and I got three control rods (26, 28 and 30 Pounds) and SEVERAL springs to sort out the bullet grain/Powder loads. I used Blue Machinist dye and marked the plastic part of the frame so I can SEE how hard each bullet I used marks the frame. I am SOO HAPPY, as it not only takes about 30% of the actual recoil OUT OF THE GUN USING THE 180 Grain Underwood loads, but you can tell that the slide BARELY touches frame (it takes much Testing, swapping and making a chart to record this info so you know WHAT ammo to use with what springs).
This Triple Spring System is absolutely the Problem Solver to the G20 and using HARD AMMO, and not hurting the guns longevity. I made a video on YouTube if you want to see how it works at: https://www.youtube.com/watch?v=SD31pGGq4ig
I hope this helps any of you, and I am going to Post this on the main topic page tonight as well, to share what I have learned and help any of you that have been using single springs to help this problem. Guys...IT WORKS!!! It was the best $150.00 I ever spent on any automatic gun. Since then, I put it (DPM) in all my guns from my 1911 to my Walther P99 it worked so well. Good luck, and if you have any questions you can reply to my new post I am about to put on the main page. Thanks...Thomas
Reads like an ad... Buy me
Long ago I posted info on them and still use one in the XD. I didn't see many/any Glock owners giving it a try.
Here is that info:

Did you do a part 2 to that video? It would be nice someone showing it run with actual Underwood using stock and DPM.
