I picked up another rod for my 17 but this time I went with the ISMI spring to compare. I found I could still run a 13lb but the 15lb felt better. Most of my other Glocks use ISMI so I will stick with those but either spring seems to work well in 15lb with my Gen 5's.
Since the short test session I have only shot a 150rnd club match. I started to feel what I thought was grit in the break but by the end of the match it smoothed out. I remember him mentioning in one of his videos to give it a few hundred rounds to wear in.
Performance wise it's impressive. Travel is super short and pulls light while running the 4.5lb striker.
Anyone else noticing a need to run a slightly heavier spring in the Gen 5 to get the same results? I think the new longer guide rod is reducing a bit of spring preload.
I received my comp kit today and was able to get in a quick trip to the range. Very impressive with no adjustment needed. I'm still undecided on the break and think I will need to put a few hundred more rounds through it to really get a feel for it. I can say the pre/over travel and reset are the shortest I've seen and all the safeties are working.
Dillon seating die? If so I found you will get the ring those and some other plated bullets. I never found it to effect accuracy. Despite that it always did bother me so I have since switched to a Lee die.
I prefer 147's and just about everyone I know does as well in their Glocks. I've always had good luck with Titegroup (3.0 coated & 3.2 plated) and 147's rn or hp around 1.140". Do a search and you should find plenty of info.
Both my Gen 4&5 had the standard (7534) release installed from the factory. The extended is only a +.75mm difference with a bit larger radius on the corner.
The Vickers release is nice as well.
The magwell isn't a huge difference but definitely an improvement especially once you get a grip plug in.
As for accuracy I never had any issues with the previous gens. As an update in that department my new Dawson Gen 5 specific sights have me shooting POA/POI.
I just picked up my G5 17 last weekend and other than the stock plastic sights having me hitting low I'm very happy with it.
I typically like the dot connector but in this gun I threw in a polished minus connector and found I prefer that. I tried a 4lb striker spring and it wouldn't reset the trigger safety and the 4.5lb would just barely. I may order a 5lb and a plunger spring to try but for now I'm happy with polished OEM parts and springs.
You should be able to easily accomplish that with a little polish and a lighten striker spring. If that's not enough Taran Tactical is now offering their GM 3.25 kit for the Gen 5.
