G35 Gen 4.

Thanks for that suggestion. Easy enuf to throw in a g17 slide stop, and if that doesn't fix it, I'll just take it out.

I thought about taking it out (the slide stop) just wasn't sure if there would be a down side to doing so??

Yes, randomly with all mags. Mags are stock Glock (no pmags or others).

I built a G35 for a distraction from 9mm major for open (IPSC). I built it using a G35 with a KKM comp'd barrel, Gomney Alpha trigger and a few other bits, but left things like the locking block and slide stop and spring are stock. I've been loading 180grn pills with various powders and for the most part it's been fine. Recently tho, I've started having an issue where the slide will lock back for now reason. I know I'm not riding the slide stop, I've had others watch my thumbs and confirmed I am not pushing the slide stop up or touching it in any way. It was fine most of last year, using the same loads (TG to WAC with 10 grn fcp pills. Any idea why this has started now??

So, on Sunday I was able to run thru about 160 rounds from my 8 mags. I had 2 ftfs both with the same mag #3. All the others worked beautifully. I then went back to some old notes from a while back when I was having other issues and it turns out that #3 was the one that I cut off 1 coil (it was suggested by someone) and I never fixed that spring. It now has a full length XP spring. The 2 that I stretched the spring worked beautifully. The other 4 with different front lip widths also worked beautifully. I think my next step will be to get all the lips to a std width and also stretch the springs I have until I can get some Wolff (or other?) XP springs. Thanks guys.

OK, so I've got a coupe of different front widths to test. I've also taken 2 mags and pulled the springs to extend them to at least temporarily provide more tension - getting anything in Canada these days is almost impossible - but if this helps, I can extend the others. Hoping to get out in the next couple of days to test the mag changes. I'm running a 10 lb recoil spring right now, would it make sense to increase or decrease? Is a stronger spring going to "help" the rounds get up the feed ramp, or would a lighter spring give more time for the slide to move and strip the next round?

Thanks. 10 thou wider in the front I presume?

I've made a lot of progress eliminating issues with this gun, but still have a feeding issue. About 1 in 10 rounds will seem to drive into the left hand side of the slide and miss the feed ramp and jam the slide. Pulling back on the slide the round drops free and in most cases the next round will feed no problem. I have done a bunch of polishing including the bottom of the slide and the bottom edge of the breach. Currently running a 10lb recoil spring, but have tried others from 9 - 13 and no real difference. My mags are stock large frame with the GCE base pads. I have a block in the base pad that puts a little more tension on the spring. Mag lips are all at ~.348" at the front. My rounds are 124 Campro RN with ~7.4gr WAC and an OAL of 1.16. I've tried other lengths, but they all seem to have the same issue. Shorter will do this more often it seems. I'm thinking this is a mag issue? Should I try to adjust the lips to try to angle it a touch to the right? Open up the RHS lip and pull in the LHS lip? Any other thoughts?

Thanks for the replies. I've tried a couple of things: 1) bent in the LHS mag lip a few thousands just to be sure there was nothing getting in the way. 2) tried loading out to 1.17 again, more as a process of elimination type thing. Also replaced the slide stop just to be sure. I also put a thin piece of tape on my thumb rest to keep my thumb a little out from the frame. Seems to have stopped after that. I guess somehow I was bending my thumb a little and pushing inward to push up the slide stop without knowing I was even doing it. Odd that I only started doing this now after owning the gun for close to 3 years, but I suppose stranger things have happened.

I just tried that and there seems to be no interference regardless of how far forward the next round is in the mag.

I seem to have developed a new issue with my Tanfo Gold Custom Eric. the short version: it gets locked open randomly before the mag is empty. Pushing the slide stop down releases it and loads the next round. the long version: gun has been running fairly well lately, with main load being wac usually somewhere between 7.2-7.4 gr, using a 124 jrn at 1.162 +/- oal. It started a couple of weeks ago, so gave it a full cleaning and after that didn’t help, I replaced the slide stop. No change. Had a 10.5 lb spring in it, changed it put for 11.5. Made a slight difference, but still had it happen on both 7.2 and 7.4 gr loads. Happens on all my mags. I have a thumb rest, so thumb is nowhere near slide stop. I’m at a loss to figure out what’s causing this or even what to try next. Even heavier spring to try to get the slide back forward quicker?

Might be a dumb question, but is there any advantage to, or can you even, roll size nickel plated cases? I get a lot of brass /nickel sourced from local LEOs who seem to love their nickel, and also use Glocks. I generally haven't been using it for my Open gun, but was thinking of trying some.

Sorry to resurrect, but what was the ultimate fix for the feed issue?? Also what recoil spring are you running (once fixed)?

Anything longer than oal of 1.155 gets stuck in the chamber. Haven't had a chance to get any ream work done to it (nor should I need to really...)

Having an issue with my Tanfo GCE. Getting rounds that will nose dive into the feed ramp and not get pushed up into the chamber (essentially a form of FTF). This happens mostly with JHP projectiles (Zero and Hdy) and much less so with any kind of RN. Gun currently has a 9# spring. Most common load is 125 Zero JHP with 7.1/7.2gr WAC oal of 1.150. Have tried slightly shorter oal at 1/145 a well. What to do: 1) load even shorter - 1.13-1.135? Can't really go any longer than 1.15 ish as they just get stuck in the chamber 2) heavier spring? I have a 10# spring, wondering if this would allow it to push the round up and in? 3) Use RN and skip the JHP? With 124 coated RN it seems to run quite well, but all the cool kids are running the Zero 125gr JHPs?? Other? TIA

I was having the same issue, thinking it was the case ramp thing not going in far enough and pulling out a bunch of hair. I finally tried the method described in the manual (tightening the lock ring with a case in the die) and haven't had the problem since, regardless of what die I use (including Dillon dies).

After power cycling the tablet, this time it works fine.

Neither end cycle or run do anything.

I'm playing around with my new M7Pro / S1050. I presume to setup dies etc you use the "move to bottom" to do things like set die depth etc. After using the move to bottom, I seem to have to re-calibrate before being able to do anything else. Is this normal? What am I missing? TIA

I have had a very similar problem with my 650 for a while. The case seems to go into the shellplate at stn 1, but 1 in xx would then have the trailing edge of the case hit the sizing die and the only way to procedd was to give it a little nudge into the die. The fix was to rtfm and follwo the process to tighten the die (with a case in the shellplate) as per the manual. Honestly, I've had this machine for 5 years, and somehow I totally missed that any time I've read the manual. Even bought a 1050 recently and didn't register that when I've read that manual. Once I did it according to the manual, I haven't had a case not feed correctly, going on a couple of thousand now on the 650. I'm probably somewhere in the same round count as you (25 - 30K at least) and I have veru little wear on the machine.

If you already figured it out, ignore this. However, I have had the same issue a few times. In my case the mag would get stuck too far up in the gun and it would stop the slide from coming forward. The only way to clear it was to pry the base pad down and forward. A couple of calls later and I was sent a new mag release and once I installed it, the mags no longer get stuck in that position. First pic is with a mag stuck in the gun. Second is the opposite side (rounds are dummy, no live rounds in there).

Has anyone used XMetal coated bullets for 9 major? They make all kinds of claims about being clean, safe, chemical free, lubricating and a touch faster than others. https://xmetaltargets.com/product/handyman-9-mm-124gr-hi-tek/ These are local for me (in Canada) and I've been able to get good velocity with 6.6 ish gr of WAC with a 124 gr rn. Gun is a Tanfo Gold Custom Eric.
