Glock 10mm question

[Karl Blanchard]

Love my long guns but not really a pistol guy. So for you glock experts, do I need to upgrade recoil spring to run the heavy buffalo bore hard cast?

[Oh Mah]

most say yes,mine has been done as i don't run max powder loads.

Did you overcome your fear of hunting in grizz country?

[porcupine]

No. I have heard of others doing this and it only causes other problem like FTE's. I have a stock RSA in my G20 and have experienced any problems and it has handled everything I've fed it.

Does Alaska count?

have you by chance tried the 220gr buffalo bore?

Karl - I just bought a G20 last week and have ordered a new guide rode and 22# spring.  I'm going to test the Underwood 200 and 220 grain flatnose over my labradar to see what velocity difference I get between the OEM spring and after market set up.  Will also try to assess recoil and muzzle flip.  From what I've researched some users say the stock gun performs fine...others have failures. 

I'm sticking with the factory barrel for this test.  If accuracy sucks then I'll upgrade to an Alpha Wolf or KKM.  I expect the factory barrel to perform just fine.

By the way, A GS chest rig is on the way for this gun too.

well hurry up!  I leave for AK in 3 weeks 

But seriously, my reading has been similar.  Some say it's a must, some say dont touch it 

[porcupine]

No, I have not.  I just checked out Buffalo Bore's web site. They have an interesting and detailed paged for the 180gr JHP and not much for the 220 hard cast flat nose. I confess, Their 180gr are hotter than my max reloads and I might have to give them a try. Thanks. They recommend the stiffer recoil springs to control the extreme velocity spreads, over 50 fps. Are you experiencing this?

[CaNINE]

The pressures on.  I may get out there in the next week or two.  You over on the east side of the hill?  If you're over this way we take these guns to the range and put them through the paces.

To be on the safe side you might consider the 200 grain Underwood ammo.  There seems to be consensus that it performs well in the stock guns.  200 grains of hot lovin' running at 1200 FPS is going to drive deep into bear flesh.  And they're even on sale.

I have the same setup,  lone wolf barrel + SS guide rod and 22# recoil spring.

On top of that I've changed out the sights to trijicon night sights.

another thing you'll eventually need to do is change out the magazine springs to +10% heavy duty magazine springs. 
I had fail to feed issues on stock magazine springs, the HD springs cured it.

just for chits and giggles..
 I loaded up 3 magazines randomly stacking in each magazine 180gr stock double tap bulk ammo,  200gr underwood high power, and 220 grain underwood ammo in each magazine and rapid firing it. I of course would never do this in a real world scenario but I was reliability testing the gun. 

it ran flawless, with all the brass travelling far enough away to be acceptable,  nothing landed at my feet nor did anything eject 20 feet away. 

For accuracy I was hitting an 18" plate constantly at 100 yards

On my g20 I left it alone and never had issues regardless of the round I shot. It ate everything. I have a g40 set up with a 22lb spring. As this is a hunting rig I find the heavier spring easier to recover from recoil making for eaiser follow up shots with the max loads from buffalo and underwood. My opinion is that the stock spring will likely do just fine but with the heavy loads it slams back to the point I somewhat expect the slide to fly off over my shoulder. The heavier spring brings that closer to stock spring with target load cycling. I have also shot the 180 grain armscor target ammo from the heavier spring and had no issues. To be honest while ugly the glocks fit my hand and shoots really well for me. The only time I have seen one fail is from new shooters limp wristing. Of course this is my experience and my

Well I'm thinking a spring is cheap so may as well. Ordered a new spring, some 220's and those 200gr Underwood.  Already into this goat hunt basically all of my annual hunting budget so what's another $8 for a spring

So maybe the mule deers will get a little relief this year?

I highly doubt that. He's got a sickness
