Hi,
Here is my new build I need help with - done on top of the existing properly working G17.
G34 complete slide is brand new. It has no cutoffs on the top - solid slide, looks same as G17 gen5, only longer. Spring and rod part is identical to one in the G17 - has a mark 13 on it.
The question is for the owners of a similar gen 5 G34 guns - do you have an issue with 115gr ammo?
I took gun to the range today to test it and setup sights. Took 'venom' rounds with me -
http://www.medefence.net/ - those are supposed to be 115gr.
So, what happened is this - the slide would eject shells fine - but, the cartridge would not load in properly in about of 50% shots - it looked like slide was not able to push the cartridge into the barrel completely, so, it would be needed in most cases to manually pull slide all the way back, shake the cartridge out and manually reload. partially loaded cartridge would be sitting at some angle toward the barrel but not in it.
I went over 2 mags like that, then dismount the leupold red dot scope to remove that weight. It improved the situation somewhat, bringing issues rate down from 50% to 30%-20% underloaded cartridges.
So, the question is - among those Gen5 G34 - is it an expected common issue for 115gr loads to be insufficient to properly cycle the weapon? The obvious solution is to try 124gr and heavier loads - but - i was intending to use this as a competition gun and it would be very nice to make it work with 115gr loads with no issues.
Also, during that ordeal i removed G34 slide, placed on G17 slide - it cycled with no issues, i ran 2 mags of those venom rounds through it. I then took spring out of G17 slide and placed it into G34 - got no improvement of the issue, it would still get stuck on the reloading step same way. This G17 slide was may be through 400-500 rounds so far - so, it is fairly new too.
Range folks suggested several things - one was a hypothesis that may be my right hand grip is too loose for long barrel G34 and that messes up recoil force and a reload cycle - i will test that.
Other thing - OBVIOUS - was to use heavier loads. i will test it too. only others i have now are 'red army' 124gr. they used to be fine in sigs and glocks i have - will see.
Then, as I would really want this gun to take same rounds i use just fine with the G17 - cheap 115gr ones - we talked about ideas of replacing spring with a more stiffer one - that i am not so sure how to proceed with. I know of this product
https://www.glockstore.com/Wide-Diameter-Recoil-Springs?quantity=1&color=1&custcol7=99
but not sure which one to choose.
also I am not sure if it makes a lot of sense to do at all - so - i wanted to post it here in a hope that i am not a first one getting similar issues with a G34.
PS. I am fully aware that 'venom' is an absolute junk - do not punish me for that - but - i was totally out of ammo, so, i got a 500 of those, 50c each, to waste. G17 used to eat them fine, anyway.
