So just bought my G40.  I know I want to load it with Underwood or Double Tap but which ones? Both sell several different 10mm rounds.  Thoughts and opinions are welcomed.
thanks in advance.

Underwood ammo is my choice for 10mm.

Underwood all the way.

They actually hit advertised velocity. The same cannot be said about Doubletap.

Have you taken a look at some of tnoutdoors9 10mm ammo reviews on youtube?

Georgia Arms 10mm is also really good and it has never given my G20 any problems. Underwood in 155 has given me issues, while Underwood 180 and 200 have been really reliable. Do you reload?

If you want cheap practice ammo, SG has 180 grain S&B for sale at $13.95 a box if you buy 20.  Don't think I have seen 10mm this cheap in quite a while.

180gr and 200gr XTP's from them are fantastic.

200Gr is a little much for carry. I use it for woods/hiking.

180's are for winter carry primarily.

I used to reload but hardly have the time to shoot anymore.  Working 60 hours a week and going back to school full time is kicking my ass.

So the 165 for everyday carry? Obviously I don't know jack about 10mm yet.

Double Tap has finally adjusted their advertised velocity to reflect reality. I still hold their dishonesty against them, but that results in a tough choice. Underwood is seriously hot, reasonably priced, and honest while the ammo that DT makes produces velocities that are more appropriate for the projectiles. I think the Underwood 165 gr Gold Dot is a little too fast for the bullet design, but DT pushes it to a speed that is more reasonable and results in better performance.


Or skip both. The load you want depends on what you want to do with it. Woods defense? I'd probably go with 220 gr hard cast, Federal 180 gr Trophy Bonded soft point, or a 200 gr XTP. For personal defense, virtually any 165 - 180 gr JHP, especially Gold Dots, will work well, but the Hornady 175 gr Critical Duty is pretty legit.

I've done a LOT of gel testing (69 tests and counting) with 10mm. All in calibrated, 10% natural gelatin. Take a look at this playlist if you have time.

Be careful about going above 200gr in a stock Glock barrel. At least in the G20, the bullets don't get very well stabilized in some guns and result in sketchy performance. Check out how they run in your gun before committing to field use. If they don't stabilize, a lone wolf barrel or other aftermarket swap out barrel will usually do the trick.

Yea, I run a Lone Wolf in the woods with the 200's and 220 gr Underwood stuff.  Regular barrel works great for all the others. I use these for carry..150 grain Nosler

While I haven't tested that particular bullet, none of the 155 gr or lighter lead core bullets that I've tested have met the 12" minimum standard. I do not recommend anything lighter than 165 gr for defense.

So for basic carry the 180 XTP Jacketed would work or should I go with another round? Wanting to avoid buying several different rounds which I know is sometimes not avoidable but hopefully I can get by with one.  Normally will be carrying a G26 or 43.

Based on my experience with the 10mm that round is best for all around use both SD and for general woods/farm use. However experimentation with your bullets in the field is required and you should also judge the accuracy of each load for your own purposes.

The weight or the bullet?

The XTP, from what I've seen/watched, performs pretty dang well at 10mm speeds.

200Gr is going to give me a boost in penetration for wildlife.

180Gr seems to hit the sweet spot for adequate, but not excessive penetration for carry ammo. 15"-16" mark.
