DPM RECOIL MULTIPLE SHPRINGS REDUCTION SYSTEM

Don't really want to know if you would install one or not as I know a lot of the die hards on here wouldn't change anything on the Shield, but if you have installed one in an MP Shield 9mm I would really be interested in hearing if you had difficulty inserting it into the slide.
I tried to install the "strong" spring and I couldn't get the spring to stay where it belonged in the front of the slide and when I did then tried to get the stainless rod in place it seemed to have a mind of it's own. A friend helped me put it in. Had to use a round rod to put it in the front of the slide and into the spring to get it in place. Then the rod just kept moving to the side so, while my friend was pushing it into place I used a small screw driver to move the rod so it would fit.
Haven't fired it yet with the spring installed but it does work good and it is easier to rack the slide.
I'm hoping the spring will ease up a bit so it won't be difficult to put in by myself.
If anyone else has an idea on how to do it please let me know.....

There are several ways to install non-captured guide rod springs. Below are several simple inexpensive tool I have fabricated for such a task as well as useful for other compression type assemblies. These tools eliminate fighting a buckling 16-24 pound recoil spring and allow you to install them using just your finger tips to activate the vise.

You do not have to use guide rods per se, just round stock aluminum bar of the proper diameter works nicely. In this illustration a factory captured guide rod has been disassembled to be used as the slave guide rod.




You are welcome.

OMGGGGGGGGGGG....
Yeah thats what i wanna do, waste my time with something that isnt worth messing with.
There`s nothing wrong with the OEM captured guide rod assembly... its way easier to deal with than this mess.

I get that your trying to help, mp9werks, lol, but this is just ridiculous that people would want to even waste their time doing this. Uncaptured guide rods are a thing of the past, and they should be just kept there too.

Sorry, its just my own opinion

^^^ I guess I don't understand how your two commentaries contributed in the least to the OP solving his difficulties.

Your statement that "non-captured guide rods are a thing of the past" is shear nonsense.

The last time I checked most newly manufactured 1911's continue to use non-captured guide rods and they are certainly not an obsolete platform.

OEM captured guide rods have a single fixed spring rate available and thus do not allow for those that reload, compete, use compensators or suppressors in order to tune their recoil system for maximum reliability. Entire businesses (Wilson Combat, Wolff, ISMI Spring, etc) of flat wire spring variants are built upon catering to just these needs.

Well, the problem seems to have gone away. I was in the process of getting the pictures for you, then I tried to reinsert the DPM guide rod and spring and I didn't have any problem doing so.

I would guess my original problem was the spring was just new and needed to be worked out. While I had it installed I worked the slide back and forth a few times and left it to the rear over night. I guess it was enough to loosen it up.

Problem solved.

As strong as this spring is I don't see where I would have a problem with the slide slamming into the frame. It would seem that if anyone would have had this problem it would have been addressed in the reviews of the DMS.....
I admit I had my doubts about the other Stainless Steel guide rod that costs $40. which is why I decided on the DMS.

Well since the OP was talking about a striker fired gun to start with, and not 1911`s... and the majority of the striker fired guns TODAY, have captive recoil assemblies. So at this point, i think your taking it way out of context than need be as well. And i didnt read anywhere in the rules when i joined this forum, that i had to have everybodys contribution fix for them either. I simply just stated my own personal opinion on the matter. You seem to have all the answers and pictures to answer everybodys problem quite well, so continue to do so my friend.
