Glock recoil springs

Why are you wanting to change recoil springs?


Good question. I've used Glocks for about 13 years and a friend of mine since they were imported (1986 or 87) and only once had to change a recoil spring and guide. That was when the guy broke the guide putting it back together wrong. I was a LE firearms instructor and oversaw several hundred Glocks so we're not talking a small sampling.
 
the factory springs in most models should cycle about anything but super light loads...you could trim a little off a factory I guess? They are less than $10...I wasn't aware of the guiderod rule....I assume that is if it's not factory? Anyway I use Wolf one piece non-captured guidrods and have an assortment of tuning and replacement springs...I trust a solid one-piece design...and I use wolf springs so that just makes sense...I've never had a failure of a factory $7 assembly but they do tend to get chipped and chewed up looking....still....for $7 you get a whole new one. The only one I've seen broken was a GLOCK 30 with the dual recoil assembly...a customer decided to strip it down and tried to re-assemble it before I got there and "sproing" it went (cracked the base off having failed to seat it properly) GLOCK sent a replacement free. It was a little disturbing how easy it broke though...so although I've never had one fail...I still preffer the wolf one piece...which their springs fit perfectly so that's nice.

I shoot factory weight in my 21SF and +1 in my 23. I will order the lower power calibration set for the 21 if my 21 fails to cycle my target loads with the 17# spring...but I havent gotten a stainless barrel to shoot lead through it with yet so it hasn't been an issue (200gr SWC with a whole 5 gr. of Unique) it's a nice paper puncher and you can deffinately let anyone shoot it all day! It ran fine in a 5" 1911 with 18.5# spring...but then the 21's slide probably has more mass....so who knows...time will tell. Years ago I went up in spring power several pounds in my old 21 and found it increased recoil and decreased my accuracy....weird huh? You never know till you play I guess.

Setting it up for IDPA. Just received a Wolff Calibration pack of 15#, 14, and 12. I will have to use them uncaptured. Got a Ghost Rocket connector with ot stop, increased power trigger spring, aand reduced power striker spring. With a lot of polishing, got a 2# trigger. Shooting 147s Berry plated bullets at about 850fps to make power factor. Wanting the flattest cycle I can get. No :) muzzle flip.
