I bought my EMP 9mm soon after they came out and mine was in the first early batch where SA changed the angle of the feed ramps.
Mine is on its 3rd return spring with 7700 rounds and the book calls for replacement at 3000 round mark and my first, original return spring went 3950 when I heard and felt some slide slaps. So at 6750 I replaced it again.
I found out a very interesting thing when I ordered 3 sets of return springs which was, IF you want both the small and long you need to order the complete return-spring guide/rod as it is a captured guide rod system - WITH THE EXCEPTION of, one need only replace the long outer spring and it has worked just fine, now thru 7700 rounds.
So just order the outer long spring and you can stay with your original guide rod and little inner spring - This, told to me, by my gunny, 1911 specialist and its worked perfectly for my gun.
Ammo sensitive - yes, some have tight chambers, mine does, and I use only new 115gr or 124gr FMJ for range practice and 124gr JHP's in Federal Premium or Speer Gold Dot.
I had issues with Hornady TAP 124gr JHP's as they, being a tad shorter, length wise, and the narrow cone / \ shape bullet vs the 2 mentioned that are a tad longer and have the more round/bullet shape ( ). The Hornady's bit/bite into the feed ramp and jammed along with left scare like hits across the feed ramp.
I found that using 600 or 800 black wet/dry, but wet, sand paper by hand/finger/lightly, up and down only, took out the scars, smoothed up the feed ramp, which, I then used some Flitz gun polish via Q-tip on the ramp until all the black was gone and the Q-tip remained clean, let polish dry, then with dry Q-tip clean out barrel chamber (only twice so far) and use a clean small part of cotton T-shirt for ramp, again, only up and down motions.
I Flitz the ramp every 1000 rounds and have had no problems with new FMJ ammo and no problems with the 124gr JHP's mentioned.
Side note: tried some Winchester Ranger sub-sonic 147gr but had a few FTFC issues, so test out your JHP's for sure and IMHO stay away from any re-loads.. ommv
Great gun, totally dependable/reliable and dead nuts accurate
You will enjoy, as mine and many others 9mm's are a well proven gun, keeping the rails, guides, and barrel lugs lubed, with the in-between total cleanings/lubrication cycles, using the add oil vertical-method every other week, if on stand-by, then cycle slide 4 or 5 times, wipe clean, load-up and go with confidence.
They go boom every time, at-least in my experience, so far.
