I just finished customizing my new Glock 20. I didn't know if Glock was going to make a 20SF, so I built one. :)

Brand new Glock 20 (picked up on Feb. 14, 08) - BEFORE

AFTER - Polished all internal parts, hand fitted a Bar-Sto G20 10mm Barrel, Tru-Glo T.F.O. sights, Ny-1 Trigger, Ghost 3.5 connector, ISMI 22 lb. recoil spring, ISMI Stainless steel guide rod, Grip reduction and stippling (done by me :) ) That's it for now.

Very cool! You had the sights installed? Or did that yourself? I'm familiar with the NY trigger, but thought that it had an 8 lb pull. But you say you installed a 3.5 lb. connector?

Both mine break right at 4.5 lbs., which is a good compromise. The 2 year old G23 has a better factory trigger than the orig. almost 20 year old G19.

On all my pistols I usually install an aftermarket barrel. On 1911's, the average reduction in group size is over 2" with a custom barrel. I use Briley or Bar-Sto.

So when I got my G19 it shot great, but still sent it to Bar-Sto for them to fit one. A couple hundred dollars later I got it back, and my group sizes shrunk by... 3/8". LOL! The factory barrel was that good.

Thanks for sharing. Good closeup pictures too.

P.S. I guess it's just me but I really don't like the ISMI springs. I bought two of them (Glock has changed their spring weights several times over the years), but neither one would fit over the stainless steel aftermarket guide rod I bought years ago, or over a Haarts Recoil reducer rod. The rods made 10 and 15 years ago had a larger OD.

I ended up ruining one spring trying to drill it out. It was just on the spring end coils. There's no need for them to be that tight. Switched back to Wolff springs and they fit fine. I would use the ISMI springs on a factory style captive guide rod, but I like the flexibility of the non-captive spring/rod setup.
 
If you contact a Glock dealer, you should be able to have them get a G21SF lower for you. Then just install the G20 ejector housing and drop on a G20 upper. All the new mags I've seen for nearly all calibers have the cutout in the mag body for the SF mag release. Of course, I'm just a guy on the internet, so refer to the wisdom of an accredited Glock armorer before listening to me.

Great work on the grip reduction for your G20, BTW!

I did all the work. Including the sight install. The standard Glock trigger pull is about 5 lbs, but the coil spring sometimes break. I had 2 break on me, so I went with the NY-1 trigger spring (8 lbs) with a 3.5 connector , thus making 5.5 to 6 lbs without the trigger spring snapping. When I polished out the trigger contact surfaces, conector, firing pin safety plunger, and portion of the trigger bar that disengages the firing pin safety plunger, it gives me on average a 4.6 to 5 lb trigger break.

The ISMI spring are working fine for me when I use their SS guide rod. So far I have not encountered any problems. The Bar-Sto's for my guns shoot in the 1" mark at 25 yards with the loads it likes. I guess I have been lucky. I like the Bar-Stos and other barrels because they offer more case support when I shoot hot loads. :)
 
Just got back from the range with my new baby! Damn, I'm tired. It's been a while shooting real 10mm ammo.

I shot 500 rounds total (Double Tap ammo : 100 rds of 180 gr FMJ, 100 rds of 135 gr JHP, 100 rds of 155 gr Gold Dots, 100 rds of 165 gr Gold Dots, and 50 rds of 180 gr XTPs, 20 rds. of 155 gr Hornady XTPs, and some 30 rds of Winchester 175 gr Silvertips.

No malfunctions at all!
