GunBugBit Posted March 23, 2018 Share Posted March 23, 2018 (edited) My friend will be shooting his first USPSA and/or Steel Challenge matches soon. He has a new Gen 4 G34, belt, holster, pouches, pretty much ready to start. He has been looking into reloading and has questions that I can't answer very well because I reload .45 ACP for my own 1911s. I'm settled on my recipe and haven't thought much about 9mm loads. He is asking if he should go light or heavy with the bullet. All I've told him is that less powder is needed to get a heavier bullet to a given power factor, and they might shoot softer. So he says, should I go with 147gr then? I don't know for sure. So I said, try some factory 115s, then some 147s, maybe some 124s, and see what you like best; we can chrono them and I'll let him know what power factors he is shooting; then we can work up a reload recipe that is similar. That's about all I can think of to tell him for right now. I also mentioned that he will probably want to try some different recoil spring weights than the factory spring in his quest for reliability, minimal muzzle flip and best feel. If any of you guys would be kind enough to share 9mm load recipes that you like in your G34, I'd appreciate it. In general, my friend wants to be above the minor floor and be sure he can knock down steel poppers, but have a reliable, reasonably soft-feeling load.

NWfront Posted March 23, 2018 Share Posted March 23, 2018 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.

wtturn Posted March 23, 2018 Share Posted March 23, 2018 I would actually advise against doing a lot of experimentation and load development as a new or early shooter. 1. It's going to retard growth by sucking up time that is better spent learning how to play the game, and 2. They have no requisite technique or foundation so they're not going to be able to tell the difference anyway. Have him pick a load, and stick with it for at least a full first year. I like 125gr coated bullets, but it's really irrelevant. I'd suggest 124/125 for cost reasons. 125gr coated lead 3.8gr of Titegroup or Sport Pistol will make PF through most anything.

I agree with wt. Just get a load that runs reliably and makes power factor. There is so much to learn regarding shooting. Fiddling with loads is down the road. Getting one's grip and learning how to call shots is much more important. Having said that, a lot of people use NWfront's 147 load, me included.

cs62 Posted March 23, 2018 Share Posted March 23, 2018 I had a G34 awhile back and my load for it was 4.3gr of Silhouette with 147 gr Xtreme PRN and CCI 500 SPP. It was soft shooting. Link to comment Share on other sites More sharing options...
Beef15 Posted March 23, 2018 Share Posted March 23, 2018 Coated 147 3.0-3.2 Titegroup or Bullseye 1.14 or shorter if he has to. Reasonable accuracy. Or go all crazy and get some 135gr coated and load them over 3.3gr of Clay Dot, very accurate in both my Glocks. With two very different profile bullets.

Almost identical to a load I've shot in my G34. 147gr RN with 3.0gr of Titegroup 1.130-1.135 OAL Recoil is more of a push than a flip. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted March 24, 2018 Share Posted March 24, 2018 7 hours ago, GunBugBit said: My friend will be shooting his first USPSA and/or Steel Challenge matches soon. What experience does he have shooting ? Link to comment Share on other sites More sharing options...
T-Free Posted March 24, 2018 Share Posted March 24, 2018 Same here -> 3 grains of tightgroup and 147 grain. One other thing I highly recommend for him is a fiber optic front and adjustable rear (have 2 sets of Dawson's and love them) Link to comment Share on other sites More sharing options...

GunBugBit Posted March 26, 2018 Author Share Posted March 26, 2018 One additional question. When shooting a load such as described above (147gr, PF around 130), what weight recoil spring in a G34 do you guys like? Link to comment Share on other sites More sharing options...
CamboSoup22 Posted March 26, 2018 Share Posted March 26, 2018 I agree on the titegroup loadout! It was definitely my favorite load in 9mm. It’s been a while since I’ve run mine but I think I ran mine at 13lbs but I was using a glock 22 conversion to 9. Good luck and happy shooting.

Beef15 Posted March 27, 2018 Share Posted March 27, 2018 My G17s runs fine with a 11 in CO and 13 in production. Probably go to 11 in both next purchase for simplicity. Link to comment Share on other sites More sharing options...

Marshal82 Posted March 27, 2018 Share Posted March 27, 2018 Go 13lb spring. To get by with a 11lb you need to have lighter striker spring or it may induce issues. Link to comment Share on other sites More sharing options...
dogtired Posted March 27, 2018 Share Posted March 27, 2018 (edited) I run a 12# spring but for me (here come the arguments) its on the edge of reliability. Edited March 27, 2018 by dogtired Link to comment Share on other sites More sharing options...
bigtimelarry Posted March 28, 2018 Share Posted March 28, 2018 I tried an 11lb ISMI on my G34 and it was nice for 1,000 rounds or so and then it barely keeps the Slide Closed.. I went back to a 13lb ISMI Link to comment Share on other sites More sharing options...
