| Hi, Just got back from montana bowhunting trip where I carried a glock 20 as backup...I was very happy with it in a desantis holster, I forgot it was there even hiking several miles...my question is, if I'm only going to use hot ammo like DT or buffalo bore, do I need to replace the factory spring? I will not be using it full time at the range, only a few to shots to keep familiar...is this necessary? thanks for input! |

You do not need to replace the factory recoil spring to shoot hot 10mm loads in your G20. You may need to replace the spring more frequently if all you shoot is full power loads instead of the watered down 10mm loads that most factory ammo is now.
The reason some use stronger springs when running full power, or "nuclear" loads, is for better performance and consistency. The way it was explained to me is that the heavier springs keep the slide and barrel locked together just enough longer to allow the full power loads to reach their peak velocity before the breech opens. With the factory 17# spring, the breech may open too soon, which causes some gas to escape, and therefore some velocity is lost. I don't know how much of a difference it really makes since I've never tested it myself. However, I do run a 20# Wolff spring on a Wolff steel guide rod in my G20, and it seems to tame the pistol a little. It also made the ejection of brass more consistent in my pistol. With the factory spring, some cases were thrown up to 20 feet away, and scattered all over. With the heavier spring, all my brass lands in a 2-3 foot circle about 6-8 feet away at about 4 o'clock. Makes finding my brass much easier. I tried a 22# spring for awhile, but I was getting some failures to lock back on an empty magazine, so I switched to the 20# and that problem stopped. |

cool, thanks for replies! guess i'll just leave it...A while ago I bought one of those buffers that goes at end of guide rod, should I throw this in there or was that just a waste of $'s? Ditch the buffer! It's not needed and you would have another thing which could possibly fail and bugger up the pistol rendering it inoperable. |
