reflex Posted February 13, 2020 Share Posted February 13, 2020 I just built a new G19 with a 2 port carver comp and even with the 11# spring it doesn't want to cycle my existing inventory of 135ish PF 147s. It cycles 124gr gold dots and 147gr HST +Ps just fine (those are 140-145 PF i think). What is the best way to get this thing to work? I'd prefer something softish shooting for training the kids/wife/etc. As of now I have no bullets to burn up, so I'm open to whatever bullet weight. Only caveat is that I'd like to avoid lead, but plated, poly coated are on the table. Also powders I should be looking at would be useful. During the great powder shortage I scored an 8# keg of 700x so I've been shooting that with the 147s I have now, but I'm willing to go with whatever.

reflex Posted February 13, 2020 Author Share Posted February 13, 2020 I shall pick up some 124s then and give it a shot. Thanks! Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted February 13, 2020 Share Posted February 13, 2020 If I had a lot of ammo lying around, I'd drop the spring until it fed my ammo. Link to comment Share on other sites More sharing options...
iflyskyhigh Posted February 13, 2020 Share Posted February 13, 2020 I think you might have a tough time making enough gas to run the comp with the 147’s and a small charge of powder. No matter how low you go on the spring. I have tried a 10lb spring on glocks before when searching for a steel challenge load, but anything less than 11-12lbs has a tough time returning the gun battery constantly.With that comp you can for sure get 124’s to run, but you might even try 115’s and use a little more powder. You will make more gas and the comp will work more efficiently and effectively as designed. I can’t comment on that powder as I haven’t used it.

HesedTech Posted February 14, 2020 Share Posted February 14, 2020 (edited) I have a G19 build, no comp, and with a lightened recoil spring it eats all my 130ish (in TF and CZ) PF 147s no problem. So I assume it's the comp which is causing you some sort of problem. I assume your slide rails are smooth and free? This is the recoil spring combo I'm using: https://www.ndzperformance.com/Glock-19-Recoil-Spring-Guide-Rod-Kit-Gen-1-3-p/ndz-g19-g3-rpr.htm Personally, other than the weight difference, my TF S2 and my son's CZ Shadow 2 shoot a whole lot softer with less recoil than the 19, not to mention having smoother triggers. But I do have fun shooting the 19 and it is a better/lighter carry gun than my USPSA competition stuff.

Sent from my iPad using Tapatalk Racking it by hand with the 11# is already iffy to get it back in battery. What other powders will work well with the 124s? BE-86 or sport pistol i've seen good stuff written about. Any others I should try? I was going to find a box of 124s locally, and get a selection of powders and do a couple of tests until I find what it likes, and I like. Link to comment Share on other sites More sharing options...
Hi-Power Jack Posted February 15, 2020 Share Posted February 15, 2020 I've used 700x powder to make some very light loads (PF110) for use in my KelTec P-11. Worked great with factory spring and was reasonably accurate at 10 yards. All with a MG 124 JHP bullet (Only bullets I had at the time). Link to comment Share on other sites More sharing options...
GMP Posted February 19, 2020 Share Posted February 19, 2020 I built a P09 with a Primary Machinel comp and it runs great with 124g RMR plated and 5.4 -5.6g Autocomp. This is about 138 -140 PF. 13lb spring. It will cycle and shoot fine with a variety of loads but this is the sweet spot. Link to comment Share on other sites More sharing options...
