The XDm action is fully cocked when the slide goes into battery. Therefore the full force of the striker spring works against the recoil spring when the pistol is in go mode(cocked). If a lighter striker spring was utilized when the PRP was installed this makes sense. Less resistance from the striker spring causes an increase in the amount of force applied directly to the slide by the recoil spring.

I found a new one today. The same step was present inside a case with an IMT head stamp. I am going to load some of these and shoot them over the my chronograph.

The shorter OAL will increase pressure/velocity. Your chronograph should confirm this. As you seat the bullet deeper consider decreasing your powder charge.

Good idea. I sent mine in to get the rear sight pin replaced. Then asked if they would replace the extractor and send me the old one as a spare. Saves me on some shipping. Did they actually give you your old extractor? Sorry for a very slow reply d_striker. My slide came back with the original extractor in place. It was accompanied by a shiny brand new extractor which lives in my range bag.

I've shot a lot of Precision Delta 124 gr FMJ with reasonable success. I traded a friend for 100 Montana Gold 124 FMJs. The M.G.'s seemed to group well. I load both to an OAL of 1.130". I use Titegroup so I can't help you with load data. Both loads shoot about 1,100 fps. I recently tried some Precision Delta 124 gr JHP. I loaded them to 1.100" OAL, again with Titegroup. This load had an average velocity of 1,073 fps. These loads shot REALLY well in my 5.25. I've played with a few 115's. Had acceptable accuracy results but the recoil was a little snappy when loaded to power factor.

So far I haven't heard of anyone making aftermarket extractors for the XDM's. It is my understanding the extractor is not a drop in part. Each one is fitted/tuned to the pistol it will be used in. When my rear sight pin failed I sent the slide back to SA. For a small fee they fitted an extra and sent it back with the slide.

Zdog I have been happy loading 124 PD FMJ bullets with 4.0 gr of Titegroup at 1.130" in my 5.25. I haven't put any over the chrono since I backed off. I started with 4.1 gr TG at 1.25" which ran at a snappy 136 PF.

If it helps the process of sending the slide to Springfield was painless and quick. At my request, as recommended by GlockOp, they fitted an extra extractor for a small fee.

I also use the Comp-Tac paddle for Steel Challenge, Falling Steel, and "both" IDPA matches I've tried. http://www.comp-tac.com/product_info.php?products_id=53

What is your general location?

I have always been told Federal is the softest American made primer. Both of my 5.25 9mm's have PRP drop in trigger kits with the light striker springs. I have been shooting WSP's all year. I had 2 failures in my last batch of 300 rounds. Upon further examination of my ammo I found a few high primers. I don't recommend you do as I do but I finished the seating those few suspect rounds with my hand priming tool. No more problems.

I like it! And a 2nd, 3rd, or whatever for no batteries required. Something like this could replace the current lighting system for my LNL. http://www.walmart.c...wl5=pla&veh=sem

It is realistic for you to find one load that performs well in multiple pistols. In fact many of my shooting buddies and I shoot almost the exact same powder charge and OAL. We're shooting multiple brands of jacketed and plated bullets in every different type of pistol you can imagine. I shoot Precision Delta jacketed bullets so I don't have any good powder recommendations for you. Hopefully others here will. Figure out what OAL will fit the chamber and magazine in all 4 pistols you are loading for. Start playing with charges until you find one that will make your desired velocity and meet your accuracy standards. For myself if I can get 2"-3" groups at 25 yards with my eyes I'm happy. What is good enough for me may not be good enough for others. That should be easy since they are similar. You may find the POI changes slightly from pistol to pistol. You may need to drift the sights to correct for windage. If your elevation is too far off you may need to change the front sight blade to correct. At close range sight adjustment may appear to be good when it's not. I learned this the hard way. My spot on shooting at 7 yards turned into 2" right and 3" high at 25. I went back and laid out a grid on some 7 yard targets and guess what, even though the holes were in the "bullseye" 80% of them were in the upper right quadrant of the grid. Once I corrected at 25 yards I still hit in the middle at 7. Good luck with your new hobby. My 2 cents.
