Suff Posted September 26, 2011 Share Posted September 26, 2011 I have my 5.25 set up with a 14lb recoil spring right now. My 147g minor loads won't lock the slide back. 130 pf. If I bump it up to 138-140pf it will get slide lock. Is anyone using a 12lb spring with success? Link to comment Share on other sites More sharing options...
cyberiad Posted September 26, 2011 Share Posted September 26, 2011 I don't have a 5.25 but I have had the "slide not locking back" issue with more than one brand new handgun in the past (mostly recently with an H&K). At the time I was only using rather underpowered commercial ammunition (standard Blazer Brass, etc) and had several of these failures with brand new magazines in the first two or three hundred rounds. I suspect that if you keep shooting it to "break it in" eventually it will lock back with any ammo without having to use a lighter recoil spring. I won't get in to the "new gun should not require a break in" debate because I think all new guns do, no matter how much they cost or who makes them. Due to "lockup issues" and the fact that it just feels way too light the lowest weight recoil spring I would use in my XDm 4.5 is 16lbs. 14 seems really light. If you shake the pistol back and forth does it come out of battery? Link to comment Share on other sites More sharing options...
PSSOH22 Posted September 27, 2011 Share Posted September 27, 2011 I'd say to just bump up the loads personally! I found tons of problems when trying to light load 9mm. It felt really sluggish. I know it is not help about the recoil spring, but it is just my .02 Link to comment Share on other sites More sharing options...
Jackopt Posted September 27, 2011 Share Posted September 27, 2011 What happens if you use the factory recoil spring with the same ammo? Jackpot Link to comment Share on other sites More sharing options...

theycallmeingot Posted September 29, 2011 Share Posted September 29, 2011 i've found that with the xdm 5.25, my right thumb rides the slide release, and most of the time it doesn't lock back. could this be happening? load a bunch of mags with one round and shoot weak-handed and limp and see if it locks back. mine did, but strong hand/freestyle, it doesn't.

Thanks for the suggestion, but I make myself keep my right thumb on the back of my left hand so when I do change from one platform to another I don't have an issue riding the safety/slide release.
