This is going to be primarily a woods gun - prepared for black bears and bad guys. Where bears are present I'm planning to load a hard cast and then a hollowpoint alternating, and where bears are not present only hollowpoints.

Glock 20 Gen 4
KKM Barrel (4.6)
Meprolight Night Sights
Doubletap 200 grain hardcasts
Underwood 180 grain XTP Doubletap 200 grain Noslers
(EDIT:Everything in this list has been ordered, I will have a range report probably in a week or two. I'm not interested in nuclear Underwood loads for this, I'm happy with another 20 grains and 100fps over .40 S&W. This will not stop me from experimenting with nuclear loads once this system is up and running though... )

Any recommendations before I pop on all this? Not going to need to upgrade the recoil spring assembly am I?

Thanks guys.

You *might* need a 22 pound RSA. I would shoot it first and see how it is. The function with full power ammo seems to vary from gun to gun, and/or shooter to shooter.

I'd go with a 3rd Gen 20 if you can find one. Plenty of upgrades available. Also for the barrel I'd stay with the stock barrel. Stock Glock barrels are really very efficient. Hickock45 did a video showing a negligible drop in bullet speed between the shortest block barrels and the longest barrels of the same caliber. Spend the money on getting the trigger smoothed out (not lightened).

Look I have an FBI model S&W 1076 that has been through the Smith and Wesson Performance Center. It is extremely accurate. I also have a Glock 29 with the stock barrel a smoothed out trigger (done by Ghost Glock) and it is almost as accurate as the S&W.

www.gunwatcher.com They have a few up for sale. I run it with the 22lb Wolff spring and steel guide rod. Eat's it all.

radiotom welcome to the forum.

You DON'T want my opinion about getting ANY Glock!   

They do not make one single model that feels right in my small short fingered hand. A 1911 feels oh so much better to me.

I 2nd the Gen 3. I bought a Gen 4 & had lots of issues. Glock replaced it with a Gen 3.

There are more options for RSA's available for the Gen 3. A lot of people have good results with the stock springs, but nice to have the ability to tailer to the load. I use a 20lb spring even with soft shooting 10mm in my G20.

Regarding the stock barrels they are great. You might see how well it does with the hardcast first before opting to buy the KKM. Accuracy might be fine with the stock for a 200gr hardcast. Hickock45 had terrible results with 230gr Doubletap in the stock barrel, but good results with a different companies slightly lighter load.

Yea Gandog56, but your going to bash the glock anyway.

radiotom, Welcome to the forum!

The G-20 Gen -4's have had some issues with the higher impulsed ammo using some of the heavier bullets.  Getting one to run correctly may lend itself to tailored ammo that the gun itself likes and functions with.  The recoil systems of the Gen-4 is different from the Gen-3's and not many aftermarket RSA choices are available just yet.  Take your time to study the choices and find people who are having success with their setups.

Companies like Underwood Ammo would produce a reduced loaded ammo to possible help your gun work with a lower impulse round should you need.

There are so many things that can cause stoppages in the newer Gen-4's, most seem to related to the impulse, slide timing and lockup, but some can be magazine related and cartridge length.  Finding a balance of ammo performance with the timing     seem to be more exacting that the previous generations.

Best regards!

So I have a G20 Gen4, running 21lb spring both with and without glock barrel and kkm standard lenght (4.6").  Consistently shooting 4-6 inches low.  I shoot g21 nuts on.  Is the G20 G3 have better accuracy?

RadioTom - have you made the purchase yet, if so what are your thougths?

Had a gen 4, sold it and bought gen3. I had problems with the gen 4 shooting hot loads. My gen 3 with 24lbs spring set will eat anything now with no problems.

How much does that gun weigh, IC?

Edit: Disregard. I found it.....1200 grams. The Glock 20SF weighs 875 grams and carries how many more bullets? 4 right?

Your Tanfo might make a nice range gun, but try carrying it for a 12 hour duty shift. How about carrying it for a day in the woods, humping up and down mountains and hills in the snow while wearing a pack, along with a rifle and ammunition, calls, and flashlights?

I don't see Glock owners interdicting on Tanfo threads here telling Tanfo owners how great Glocks are, so why the other way around?

Different tools for different tasks. 

Lets say you drop the pistol in the sand along a lake.  The action is locked open, and sand gets all over. 

Tanfoglio is done for the day.

Good chance you can blow the sand out well enough the Glock will function.  If not, go to the water, insert Glock, swish it around a bit, and your back in business.

One is a nice, pretty target pistol that may do fine in some settings.

The other is an ugly black combat weapon that is loose enough just about everywhere that no matter what happens, the thing still works.

I have a G4-G20 and it doesn't eat every ammo.  It doesn't with a 22lb spring either.  Its the extreme upper edge of the hot ammo it has issues with.  If given the choice, do Gen3 if your going to do Glock, at least if you want to run the very hottest ammo.

If the pistol isn't going to see abuse, consider something like the Tanfoglio Match for about the same price. 

I think Tanfo's holds 14+1, Glocks hold 15+1.

Taking a Tanfoglio in the woods is like putting silk on a bowling ball, unless it's the Hunter.
