XDM 10mm

[Azrckcrawler]

Had a chance to run some loads past my Labradar yesterday.  Been working a few ladders to find an accurate load for the 155gr Speer GDHP's that RMR is selling.

All ladder loads used new Jagemann brass, S&B primers with an OAL 1.255", all fps are averages of 8-10 shots.

Blue Dot ladder -
10.3gr 1265fps
10.8gr 1288fps
11.0gr 1311fps
11.6gr 1356fps
Didn't try max of 12gr

CFEP Ladder -
8.3gr 1237fps
8.5gr 1274fps
9.0gr 1335fps

Also shot some of my existing loads, interesting comparisons -

13.0gr AA#9 over 200gr WFNGC @1.25"
XDM 4.5" 1229fps
GP100 4" 1239fps (was expecting this to be slightly less than the XDM??)

Same as above but 13.3gr AA#9
EAA Match Elite 4.75" 1252fps

10gr Longshot over 165gr BBI RNFP @1.25
XDM 4.5"                   1375fps
EAA Match Elite 4.75" 1382fps

Ramjet,

Are you saying you are not having the same trigger issue?

Trigger slap yes for sure, absolutely, I agree.

[Graybeard]

Ramjet and Mr.revolverguy, does the issue you're having feel like a combination of an intense vibration and an electrical shock when you're holding the trigger all the way back? Very brief, but surprisingly painful? Kind of like a small scale version of hitting a baseball off of the end of the bat and stinging your hands?

I had a G20 I rented shortly after they came out do this to me. I've shot several other Glocks before and since and never had it happen again.

[mr.revolverguy]

Graybeard,

I struggled to describe my problem but you have just nailed it!

[Ramjet]

For me its load dependant. In any case it's not an issue for me. Just agree it exists.

[Graybeard]

I was shooting a rented G20 and G21 when this happened to me. G20 stung like hell every time I held the trigger back and the G21, not at all. I think what's going on here is an issue with harmonic resonance, the natural frequency at which things vibrate, and constructive and destructive interference. The constructive interference is increasing the amplitude of the vibration making it more powerful/painful. Ramjet's statement that it is load dependent works well with my theory as the energy impulse changes so does the frequency and power of the vibration traveling up the trigger bar and back to the trigger.

Basically, I think the trigger is acting like a high frequency tuning fork with enough energy to be painful. I doubt it is a manufacturing or design issue, more of a phenomenon when just the right circumstances occur.

My suggestion on how to rectify this would be change the frequency at which these parts vibrate. Different pins or different material pins for the locking block/trigger. The newer M&Ps have a fiber plug inside the trigger return spring. Perhaps that would work.

Really glad to see the XD runs on the 200gr WFNGC's, and thanks for posting it! I've been waiting to see reports they'd run well on the loads I want one for, now I really really wanna get one!

Dang it, gunmakers gotta stop jumping on the 10mm Bandwagon. Every time another one comes out with one, I WANTS one! I last succumbed when Ruger made the Super Redhawk in 10mm and I immediately went out and bought one.

Another 200 rounds of 180gr berrys plated over 9.7gr of blue dot without a single malfunction.

Sound like the recipe I pretty much use as my standard 10mm reload, except I use Precision Bullets .40 cal 185 grain RNF's for the projectiles.

[Ramjet]

Every magazine I put through this gun the more I like it. I ordered a nice Buffalo Simply Rugged holster and carries very comfortably and comes into action quickly. I am a Springfield fan boy but mostly for their 1911. the gun seems to partial to the 155-175 grain ammo. this us definately a keeper.

I have to admit after shooting mine about 300 rds I have sold my Glock 20! I never thought I would part with the G20 but just prefer the XDM grip and do shoot it better.

Glock 20 stock is marginal at best. After the large frame I see as well.

[Kenk]

Considering doing the same 😀

any day now, I can't wait for my XDM to arrive!

I just found the XDMs in 10 for the first time today (gunbroker)...and because I've not been around the 10mm sites for well over a year, assumed this gun had probably been in production for quite a while.  Was surprised to find it's a recent introduction..and very pleased to see a new 10 available.

I'm wondering about the stock grips...I've always thought the Springfield grips looked like they'd chew up the hands pretty fast, but I've not read any comments to that effect. Overall, would you say you can comfortably shoot a 100 rds in a session without any more abrasion than say a G29?

Looking at the 200gr AA9 loads above...those are right up there at max book (Hornady)--I'd think those would be the acid test for comfort or discomfort.

Anyway, congrats to all the current owners--thanks for the reviews and keep 'em coming, please!  This is starting to look like a very attractive option for another semi auto in 10.

Do all of the 4.5" come with just 2 mags, vs the 3 I see many of the 5.25 shipping with?
