    My wife's practice magazines each see about 3000 rounds/year.  I do clean these mags as necessary, but despite my several years of experience dealing with these things I find it very difficult to restore them to reliable operation.  What have others seen for life expectancy and what parts have others replaced?  I've tried the Tandemkross springs/rotors/feed lips but haven't necessarily seen improvement in reliability.  Do the mag bodies degrade increasing friction, or simple spring wearout coupled with the challenge of getting the spring tension correct?


     

    Hi Rick,

    What are the specific malfunctions you are seeing? Is the round nose diving into the feed ramp? Is the round missing the chamber and causing a high angle jam? Is the nose of the round in the chamber but the back of the round not moving up the breach face of the bolt?

     

    For what it’s worth. I’ve found the 10 round BX mags to be very reliable. As others have pointed out they do need to be relatively clean and properly tensioned. Most guns will run well with the mags tensioned between 1.5-2 turns. 
     

    Under tensioned can cause one type of malfunction-over tensioned typically causes a different malfunction. The timing of the rifle/ammunition combination can make a difference - As can bullet length and shape.
     

    CCI SV and AR Tactical (1200 fps) have a very similar bullet shape and are both about .030” longer than Mini-Mag. This combination of bullet shape and length, present really nicely to the feed ramp. It’s almost like they were made for each other. 

     

    Mini-Mag (1260), being shorter and having a more round bullet shape leaves a gap that the bullet has to jump before it hits the feed ramp. This can lead to nose diving into the feed ramp. Usually pulling the bolt back slightly will allow the nose to pop up and feed. This is an indication that a little more mag spring tension may be needed. Mags can certainly be turned to run Mini-Mags reliably.photo-output.thumb.jpeg.d81118942a85fc3084a71df41ef1be89.jpeg

  2. We recomened keeping the our striker spring installed.

    The Wolf striker spring is an extra power spring and the recoil spring is lighter than the stock spring. This can lead to not enough recoil spring pressure to keep the slide closed. Eg. a lighter recoil spring needs a lighter striker spring I order to keep the same amount of force holding the slide closed.

  3. The PRP Extreme Ejector™, is CNC machined out of hardened, 416 stainless steel. We heat treat the Extreme Ejector prior to machining, resulting in a more durable and consistent part, that will endure years of heavy use in all environments. The Extreme Ejector has been redesigned with our unique geometry to be thicker in key areas and lower to the frame. This results in a stronger part that is firmly mounted on the pins of the pistol, ensuring reliable, consistent ejection. The pin holes are drilled under-size, then precision reamed to the final dimension to achieve a snug fit on the mounting pins.

  4. You need to install the trigger that came with the kit. The factory trigger is allowing the trigger to be pulled too far back and the trigger bar is getting caught in front of the tab on the striker safety lever. If you install the trigger with the over travel stop, it will stop doing that.

  5. Not resetting could be two things. It could be that the trigger bar is not resetting on the striker safety lever or that the sear is not resetting the striker. The fix would be different for each.

    If you give us a call at 541 523 4474 we could help sort this out.

  6. I converted a 9mm XDm 5.25 to an open gun using the Carver mount. The problem I am running up against is that the extractor is ejecting the empty cases into the lower portion of the mount and the empty case is not completely ejected causing a jam almost every time I shoot. What modification do I need to make to the extractor to make it eject the cases on a lower trajectory to avoid hitting the mount? Thanks

    Is the mount in its farthest forward position? If not I would give that a try be for changing the extractor/ejector.

  7. Springfield Custom shop or PRP, they use the same parts so I don't think you could go wrong with either one. A fellow shooter just got his back from springfield and the trigger is awesome. I really like the upgraded trigger they use. Rich at CC and Springer are good also.

    I appreciate the recommendation but I must clarify something. Springfield uses the trigger that we designed (with the built in over travel stop) on some of their guns/trigger jobs but they do NOT use all of the same parts we use. For example they do not use our striker safety lever, sear, sear springs, or our trigger springs.

  8. http://www.x-tremegrips.com/ This is the one that PRP sells. I have them on all my XDM's and they hold up very well. The ones on my my 4.5 9mm are about a year old and have around 2K rounds thru it. There not as grippy as new, but still work well. No problems with coming loose on any of them. Highly Recommended

    Actually last month we bought the company Xtremegrips. The grips hold up quite well. I change mine out about once a year on my production gun (xdm 9mm) but they usually are doing just fine when I change them.

  9. What is the width of the XDM 5.25 rear sight notch?

    How does this compare to a bomar-style rear sight width?

    Thanks, my search did not reveal an answer.

    XDM 5.25 rear sight width is .127" The Bo-Mar style that I just measured was .115" making the XDM 5.25 rear sight .012" wider.

  10. I don't see any reason why it wouldn't. Same length as the 9mm 5.25-may be a little thicker but not that much.

    They are close to the same size. The 9mm slide is .118" shorter in over all length and .03" shorter from the bottom of the rails to the top of the slide. I have several of both in stock and had to check for my self.

    Also the .45 cal 5.25" slide (at 15.2oz) is about 1 oz heaver than a 4.5" .45 cal and 3 oz heaver than the 9mm 5.25". All of the XDM 9mm slides weigh the same (3.8", 4.5", 5.25") all weigh 12.1 oz

  11. Paul,

    Are you sure it is the stock recoil spring? The scenario you just described is dead on for a recoil spring that is too light.

    Rich

    Thanks Rich,

    Well, i can't be 100% sure. Nothing was noted on the invoice, but I guess that doesn't necessarily mean that it wasn't changed out . What is the factory rated 9mm spring for these?

    I agree with Rich.

    The factory springs are around 18.5 LBS you can go as low as 14 lbs before you start running into issues.

  12. what can be expected realistically of a drop in trigger to achieve? I have read the review but would like to know what the average guys that has installed one feels, approximate weight of the trigger before and after, description of reset and take-up improvements would be good, anyone?

    Thank you for your post.

    I have posted a video link that shows the install and compares the before and after. Judging by sales

    it will not be long before the end users start posting their results.
