second outing with Glock 20 (shooting Underwood)

[dsonyay]

Went to the range and fired off nearly 200 rounds of the Underwood Delta Elite 180gr JHP through my Glock 20 with zero issues.  Very easy load to shoot.  Even though the load is slightly reduced, it still has a good bark to it. 
Brass seemed perfect and showed zero signs of pressure problems.  In fact it didn't have any noticeable bulge at all.
I'm thinking this load would be great for carry / self defense. 

Also shot about 15 rounds of their 180gr XTP loading.  No issues. The brass was ejected about 20 feet to about the 4 o'clock position.  Maybe a sign I need a slighly heavier RSA. 
No bulges or smiles with these either.   I used the standard RSA for both loads.   
These rounds were easy to shoot as well, although when shooting unsupported weak hand, the Glock 20 really jumped around!

I shot from a rest, two handed, unsupported strong and weak.

After all of that I shot a mag full of +p+ Rangers through my Glock 19.  Those felt like 25acp after all of the 10mm shooting.  Its amazing how light they felt.

Hey glad you got the chance to shoot that thing some more, now we need to take a look at what's inside both of those UW loadings so you can copy them when you get your dies, neck expander/powder drop tube and shell plate...

Hook up with later on.

Good report!

I run a 22 pound RSA for the hot stuff.

Is the factory spring 20 pounds?

[The_Shadow]

The factory Glock-20SF is stated to be 18 lbs, to fully rack the slide on mine measured exactly 18 lbs 0 oz at lock open.

[4949shooter]

From the factory they are specified as 17 pound springs.

Shadow, for some reason yours is heavier / slightly out of spec (which is a good thing).
