31,706 rounds 7 stoppages

(+1 w/non-LCI extractor) 0 malfunctions 0 parts breakages

The G17 had just three short sessions this week totaling less than six hours on the range. There were no stoppages or problems of any kind. Also, to the continued disappointment of someone in Tukwila, WA neither the pistol nor I were involved in any dramatic gun battles this week. Sorry.

The modified Grip Force Adapter continues to behave like a rabbit’s foot, bringing luck and success. Cold F.A.S.T. runs were all sub-5 and clean this week, as they have been since installing the darn thing:

8-Aug, 4.55 (clean) : 1.53, .49 / 1.85 / .24, .23, .21

: 1.53, .49 / 1.85 / .24, .23, .21 10-Aug, 4.37 (clean) : 1.42, .45 / 1.83 / .24, .22, .21

: 1.42, .45 / 1.83 / .24, .22, .21 12-Aug, 4.96 (clean): 1.58, .61 / 2.01 / .26, .26, .24

On today’s run, I rushed my grip in the holster and needed more time to recover for the follow-up shot on the 3×5; then I caught myself looking at the target to see if I’d hit when I should have been concentrating on the reload. Candidly, I was surprised to see I made it under the 5-second wire.

As mentioned last week, the pistol was due for its 30,000 round maintenance. In addition to a thorough cleaning, the recoil spring assembly, slide lock spring, and trigger return spring were all replaced. I cannot tell a difference in the tension between the old RSA and the new one. As I’ve said previously, the current G17 gen4 recoil spring assembly (0-2-1) probably doesn’t need to be replaced as often as recommended by Glock. But to the extent possible, all factory parts replacement recommendations are followed for the pistol-training.com endurance tests.

The back-up G17’s round count is now 550. Still no stoppages but the gun continues to toss brass in random directions. While we’re all genuinely interested to see how it runs, there is this nagging thought that the gun I need to rely upon if my primary breaks might have a known unresolved issue… and that just doesn’t seem too bright. Of course at this point the back-up also needs different sights, connector, slide release, and a modified GFA to be an identical quick swap for the test gun. Perhaps it needs a different designation than “back-up.”

Train hard & stay safe! ToddG
