Need advice - sell (and rebuy) Glock 20 or continue to troubleshoot ammo?

It's the ammo, well rather the bullet shape. No doubt about it. In fact, you will notice UW doesn't sell their TMJ 200 or 220 gr 10mm bullet ammo anymore. It was not the OAL, but rather a combination of the length and bullet shape. I like and use UW, but that ammo would not feed in three of my 10mm guns. I could take say 1 each of all the different 10mm ammo I own (over 10 types including my reloads), and in random order fill mags of different guns. Guns, each one, would stop (partially feed) with the UW 200gr (sometimes the 180gr as well)

This is with Glock and S&W and LW and RMW barrels..........(my LW barrel is known tight and it for sure won't take ANY UW)

Hmm. I don't think it's the ammo. My original Gen 3 choked on BOTH TMJs and XTP hollow points. My Gen 4 can feed both.

200 grain TMJ from UW? About when was this?

I bought the 200 grain Underwood TMJ a year or so ago and haven't bought it again due to all the jams, so I haven't tested that particular round in the Gen 4. However, the Gen 3 - my Gen 3 anyway - choked on 180 grain TMJ and 180 grain XTP, but both of these - ammo pulled from the same boxes that I used unsuccessfully with the Gen 3 - fed in the Gen 4.

I tend to doubt that it's a matter of Gen 4 being better than Gen 3. I think Glock is just inconsistent with some aspect of their Glock 20s, and I just got a lemon with my Gen 3.

I had issues with two G20's (Gen 4 and then SF) with Underwood, DoubleTap, etc, until I started to load my own ammo. I'm about 500 rounds into full power 10mm loads without a single problem. I even watched a completely novice female shooter shoot half of mag from it, barely holding the gun, and still no problems. There was one type of bullet it didn't like, 220gr wide noses, but it eats the 200gr Beartooths like candy, which are even wider.

I wish I hadn't gotten rid of the Gen 4.

[Pumpkinheaver]

So far my Gen4 20 eats everything I've fed it.

All I can say is if I am looking for bear protection, I want a piece that throws the heaviest piece of lead the fastest, and I definitely want to know when I pull the trigger it will go bang, and have the next round ready!

10mm or 9x25?

[The_Shadow]

Pablo could you refine your question

10mm or 9x25?

Are you asking about a bear protection?

15 rounds of either. Which would you select for an angry grizzly?

[The_Shadow]

I'd carry the 200XTP @ 1240 fps if all I had was the 10mm.  The 9x25 is too small of a bullet even with the higher velocities, most 355" bullets are not designed for the speeds and some 357's might hold up, but you start trading speed for weight.
However I may would carry a bigger gun if I were anticipating dangerous animals such as big bears or lions/cats.  Even hogs with their quick reactions may need a hefty shot well placed to be effective.

I'd feel better with a 44 magnum 240 grain of 260 grain being pushed at the upper performance range.

For grizzlies the proverbial question is typically 5 shot hot .44 magnum vs. 15 shot hot heavy 10mm. One guy will say you'll be lucky to get a single shot off.

Wherein bear spray is recommended by a contigent of posters.

My 10mm's only hold 8 or 9 rounds, and I WOULD rather hit him with much more massive loads going about the same speed, hence my Taurus Raging Bull in .454 Casull.
