Glock 20 & Glock 29 - 9x25 Dillon Accuracy & Velocity - Lone Wolf Barrel - Underwood & Doubletap




What do you think about this video?

Crazy Aces: Da fk outta here... that's nice

Cleatus Van Damne: I honestly would have expected the 9x25 Dillon Underwood to outperform the .357 Sig Underwood by more than this.  Underwood's 125 gr .357 Sig flies out of a 4" barrel over 1500 and out of a 4.5" at closer to 1550.
I usually carry .357 barrels in my Glock 23 and 27, and was considering a 9x25 Dillon barrel for my G20, but it seems that in order to really take advantage of this round, you need at least a 6" barrel.

Vydonis: (It wont let me reply to posts)
10mm doesn't get the same fp/force the 9mm does. 6" barrel 9x25 underwood gets 1200joules of force. Highest I know of at 6" with a internal grip magazine. Upgrade to revolvers for higher joules. 10mm barely makes 1050 joules at a 8" barrel with underwood ammo.

Alex K.: Don't see a point to use the 9x25 as a carry round, would stick with 10mm.

Ammo Test: haha especially with the G29 3.8" barrel version

UndergradPigeon: Those 125s would probably make a pretty sweet carry load, you know if you're the kind of guy that wants to make an impression on the threat and deafen everyone around including yourself Haha

UndergradPigeon: How loud is the 9x25? I've heard it's pretty crazy loud and the blast is pretty ridiculous

Ammo Test: yeah I'm going to add a segment to this video showing recoil like I've done with my other ammo tests/velocity vids. pretty sure both doubletap and underwood advertise their velocities from a 6" barrel.

Ammo Test: probably just plastic lol

paper000000: I'll look forward to that. I'm curios about the 9x25 recoil. Thanks for doing these chrono tests with real world barrels, well except for the 6". I'm surprised that it took the 6" to get the advertised velocity for the Underwood but not surprised the the UW came out on top.

paper000000: How much change did you have in your pocket?

Tactical Training Group: thanks for that info and the great video

Ammo Test: probably around 80

Tactical Training Group: what was the temp the day of the test?

Ammo Test: I run a 23lb wolff spring and guide rod setup. Works for everything 10mm 9x25, 40sw and 357sig. (a little much for 357sig but it still gets the job done). I've had a few problems with DoubleTap not to many. Main problem has been on every caliber it's running slower than what the box says.

Beltfedshooters: Did you have to change out the recoil spring to a heavier one on the Glock 29? So far hows the reliability been on the Double Tap stuff running through your Glocks? Great vid!

Ammo Test: I'll put out a video with link to new channel once it's ready. Will be called AmmoTest

Richard B: Underwood is the best value and performance of any ammo manufacturer out there. I will keep buying there stuff time and time again so long as they keep the same value and don't get all elitist on us like Double Tap and Buffalo Bore. Anyways, I look forward to your future videos here. Will your new channel be under the same name?

Ammo Test: Yeah when I start my new channel I'll do just that and add it on to this vid. But 9x25 is more of a muzzle Blast than a recoil in my opinion. I must say that underwood's 357sig gets darn close to 9x25 velocities.

Richard B: You have created a great resource with your channel. I chose 2 new Glocks based on our videos (G33 Gen4, G32 Gen4, G20 Gen4). I would love to see a recoil demonstration of your G29 and G20 loaded with some Underwood 9x25 Dillon as I'm considering adding both configurations to my arsenal. Does the 9x25 have more recoil than 10mm??
