Sold off a Smith revolver I rarely shot and put the funds towards a Glock 20 SF. The idea of having 357 Mag ballistics with 15 rounds, less weight, auto format did me in. I've eyed them for years. Wanted a Gen 4, but I've heard mixed reviews so pulled the trigger on the Gen 3. The SF model feels oh so good in the hand. It will now be my woods and hiking gun where I previously carried a 4" 686 or Ruger BH in 41 Mag. After a few months look for a thorough eval of gun and caliber. I've got 3 Smith M&P autos and had an XD in the past for me to compare to. Maybe (or maybe not) ill be a glock convert. We shall see.

I think the 10mm slightly edges out the 357 mag. I own both...and with the right handloads the 10mm can really shine. Really closer to a milder .41 magnum load IMO.

Enjoy your glock. I went to the dark side with my Elite Match.

You will have to try out underwood ammo, they make some great stuff!

Mild 41 ballistics for sure. But no where near true 41 mag stuff. But I reload so ill have to get some components to get this thing to really shine.

Now for the age old question, hard cast or not.....just kidding guys. Lets keep Pandora's box closed on that one.

you could always upgrade your glock to a .40 super and it would get you a little closer to a real .41 mag but still not all the way there.

Caliber: 40 Super
Bullet Weight: 135 Grains
Bullet Style: Nosler Jacketed Hollow Point
Case Type: Brass

Welcome to the club.

I am on my second Gen 3 20SF. I have LW 40, 357 and 10mm barrels for it - just need to add a 9x25 barrel and I'm set. I use it anytime I'm in the woods for a walk, or hunting. I have full confidence in this load from DT stopping any 4 legged threat......or 2 legged meth-head.

Caliber : 10mm

Bullet : 200gr Wide Flat Nose Gas Check Hardcast

Ballistics : 1300fps/ 750 ft./lbs. - Glock 20
1105fps / 542 ft lbs 100yds Glock 20
Glock 29 - 1240fps

Thompsoncustom,

40 super was new to me. Definitely impressive velocity with that 135 gr bullet, however, I'd rather have heavy bullet at moderate speed. Lightweight high speed means shallow penetration. Even my 40 hand cast reloads use a 180gr cast at moderate high velocity. This is what kept me from the 357 Sig. On paper it's impressive. Many compare it to the 357 Mag, but its only comparable with light bullets. Start comparing a true heavy load and the 357 Sig falls flat and the 357 Mag really shines.

I'm a huge 41 Mag fan and load up 250-270gr GC designs at a little over 1300 FPS. That'll work for anything ill encounter.

Ill be interested to see what the 10mm can do with 180+ grain bullets.

I love the hodgdon load site cause it allows me a quick glance comparison grain for grain by printing off the load data.

I don't see the point in that .40 super load, I got over 1600 fps with Underwood's 135 gr 10mm load, and even that is really too fast for that bullet unless you're just interested in 'splodin things.

I had good results with 180 gr bullets over Longshot (9.3 grs I believe). I was in the mid to high 1300's out of a lone wolf 6" barrel with that load and not really pushing things. The 180gr Hornady xtp is supposed to be a great hunting bullet for the 10mm.

As far as 10mm goes you should be able to push a 180gr 1300fps which is still really good and I don't know if I would trade the 10mm for a bottle necked cartridge or not.

Hmmm. Now that's more impressive. I may have to look into this. Who makes the conversion? Cost? Who makes dies and brass?

I have zero experience with any "super" calibers. You've got to be dealing with some SERIOUS pressures to pump out that velocity :)

I bought into my model 20 3rd gen last summer with the same basic thoughts of a woods/huntin gun. with Smith 29's and such approaching 800-1000 the thoughts of beatin on one as a woods gun does not appeal to me as much as the 450.00 Glock I got second hand like new in box...

I got it and some mags right before the madness but still have not shot it enough. The preliminary results have been great and I have a dillon set up ready to go and some starline brass ready t go.

I might have to try a 1911 in 10mm one of these days as much as I like the Glock.

I own two 10mm semi autos and they do a very credible job, especially in true full power mode. If I need more power in a handgun I go to one of my .44 Magnums or 454 Casulls. If I need more than that I get an appropriate rifle or shotgun.

Handguns are great. But when the threat, or potential threat, gets high enough it's time to bring out the big guns and for me that's a shoulder weapon.

Thompsoncustom
September 8, 2013, 08:26 AM
Well the drop in barrel is about 125 new from lone wolf problem is it's for the G21. The 40 super is a 45 win mag brass sized/cut down for 40 super so you need to start with a .45 not a 10mm to do the conversion.



RCBS and Redding both carry dies for .40 super not sure who else does.

Underwood doesn't offer a 180gr in .40 super tho according to his number it would do 1500FPS.

Don't most of the .40 caliber bullets have trouble performing well when pushed to upper 10mm speeds? Would the 40 Super just exacerbate that? Extreme expansion at the cost of penetration.

Picked up a G20 in January but haven't fired it yet. Ammo. I can get my hands on a couple boxes of the PPU 10 mm and I was wondering how good it was.

osteodoc08

PPU Prvi Partizan is ammo made in Serbia. It's fine for what it is. Blasting ammo. I wouldn't be depending my life on it. I picked up 200 rounds of Remington ammo when I got mine. Hoping to run through it today.

Yes, most poorly constructed bullets fail at higher speed. As soon as some appropriate bullets are available, I get them and reload.

Yep. Underwood uses good bullets (XTPs and Gold Dots), and neither performed well when pushed to the higher velocities.

If I recall correctly, the 180 grain at 1300 seemed to be a good sweet spot according to his testing.

Thompsoncustom

Yep. Underwood uses good bullets (XTPs and Gold Dots), and neither performed well when pushed to the higher velocities.

now I only reload for 9mm but I disagree with the above. XTP's do fail at higher speeds but the gold dots being a bonded bullet hold together well I've push a 115gr to 1400fps and they all held together, but when it comes to 10mm and 40 super I have no idea.

I've seen .45 super in 180gr/1300fps and 230gr/1100fps shot with the gold dots and they also held together just fine.

TexAg
September 8, 2013, 10:46 AM
It's not so much a question of holding together, it's massive expansion that slows the bullet down and limits penetration.

Thompsoncustom
September 8, 2013, 10:51 AM
Indeed the Gold dots open up very nicely, on the other hand if you want a HP that doesn't over expand the PDX1 can be push to 1400fps with any over expansion they almost look like a meteorite or tear drop with hooks, down side is they don't sell the PDX1 and pulling the bullets to reload them is not cost effective.

September 8, 2013, 10:57 AM
Al,

I was referring specifically to the 10mm underwood velocities, which are usually at the more extreme end of the handloading area. All of my handloads from him use either the XTP or gold dot. Maybe one or two boxes has noslers (nonbonded).

His 135 grain load for the 10mm is clocked at 1600 fps. At 1400 fps, I would suspect the bullet to be a better performer.

Check out the link below on how the 180 grain gold dot performs when pushed (gold dot is still one of my favorite rounds):

http://www.youtube.com/watch?v=sl_n_miLfbY&list=PL04F5D87436EEDCA8&index=1

Hornady's 180 grain XTP loading is running at 1190 fps. My guess is they certainly could push it harder if they wanted too...but maybe they feel optimum bullet expansion should be balanced against higher velocities? Who knows...I'm no expert.

Closer to 41 and 44 mag than it gets credit for. If you consider overall size. My 4 3/4" G-20 gets a chronoed 1315 fps with Double Tap 200 gr ammo. My 3" 629 will just barely break 1150 fps with 240 gr ammo. Yea, the 44 mag wins, but not by nearly as much as most think. Now from a 6" or longer barrel a 41 or 44 mag is in a different league. But my G-20 is 3/4 lbs lighter and 1" shorter than the 3" version.

This 44 is slightly more powerful, but I'll give up that tiny increase for nearly 3X more ammo and a lighter more compact gun.

I was just out shooting a couple of 10mms today. It had been awhile as 750 rounds of 10mm made my hands sore. I need to get back shooting the 10mm's more.

10mm is the most under rate pistol out there. they should be far more popular than they are. they make a fantastic pistol for protection from toothy critters in the outdoors as well as the two legged kind

I tend to agree. I joined the 10 mm club last Christmas and have been kicking myself for not getting into it sooner! But I do reload so that is a plus.

Welcome to the club. Seems it's getting bigger all the time, albeit slowly. Personally, I have two 10s, the first, a Delta, going back to the late 80s. My second, a G29 became my woods gun for the Huron National Forest. Enjoy!

Yes I handload but I still have the blister scar on the web of my thumb to show where the witness ground into it. I should have stopped around 500 rounds and I would have had just a bad blister.

If you shoot 10mm, you pretty much have to handload is my attitude.

Well. I went to go shoot it for the first time today, but had something come up. I am fortunate enough to ride my Polaris Ranger out my backyard, hop on a road being built and end up on my deer club lease in less than 5 mins. Problem is, this road runs right through the middle of the lease. This has brought several "undesirables" that like to do drugs and deal drugs down at the end of this road being built. I had loaded up both my magazines and heard a truck start up down the end of the road. It was not in view but I could tell it was coming. I positioned myself between my Polaris Ranger and loaded up the Glock. The truck saw me and he floored it and almost spun himself in a ditch. Late 80's F150 blue in color. 2 WM with no shirts on. GA plates but couldn't read it due to the speed and dust. I notified police and our deer lease president. Got a text my future father in law showed up unexpectedly and said to hell with it and rode home. Ill try again tomorrow morning.

As a side note, my future father in law dropped off several boxes of glow ammo cold tracer stick ons for reloading in 9/40 that he had at work. That was a pleasant surprise.

The 10mm is a good cartridge. I have a gen4 Glock 20 and it's my first Glock 10mm, but I really dig the Gen4 grip and the 20 shoots very well.

I've got a few nice woods loads loaded up for it, one a 200gr WFNGC that averages about 1270 from the 4.6" G20 and a 180gr XTP that does about 1365 fps. Both are handloads using 800x and the brass looks okay from the stock barrel.

I've been a bit preoccupied with developing a good load for my gen4 G21 .45 Super, and it consists of a 250gr XTP at around 1,270 fps, it will shoot a 255gr WFNPB the same speed. 275gr hardcasts will do right around 1,200 fps and a 300gr LFNGC will average close to 1,150 fps. It's big power, but it needs a comp which is why I shoot it through a KKM 4 port barrel.
