I took my Glock 20 Longslide out for another short range session the other day. My fist range trip was plagued with FTF issues while shooting full power loads. I bought a Wolff stainless guiderod, and a Wolff extra power recoil calibration kit. The XP spring kit came with 22/20/19/17lb springs, and at Wolff's recommendation, I started with the 22lb spring. Between the longer sight radius, the Dawson Precision sights, and the 10mm cartridge, this thing is rediculous. It wasn't cheap to put it together, but it was worth every penny. I experienced ZERO FTF's with the 22lb spring, so next time I'll throw in the 20lb spring and see how it runs.
40rds Triple R Munitions 180gr JHP
This is a very mild, high precision load. Using the 22lb spring, all rounds functioned flawlessly. I was a little surprised, because I wasn't sure if these mild rounds would cycle with the much stronger spring.
30rds Double Tap 200gr WFNGC
Using the 22lb spring, NOT ONE FTF!!! When I used the factory 17lb spring on the first range trip, 1 out of every 2-3 rounds would FTF. I was hoping that the stronger spring would be the fix, and so far it was.
50rds UMC 180gr FMJ
The first 20rds I shot just to check for function. Using the 22lb spring, they functioned flawlessly. I sent a B-27 target out to 15 yards for the next 30 rds. I fired as fast as they range allows, which is once every 2 seconds. I am pretty happy with the results, and I know if I focus I can get them a lot tighter. The target below is 30rds of UMC @ 15yds offhand.
