I replaced the hammer spring and installed the steel parts kit at the same time. I've run nothing but new factory brass, but still cheaper stuff. I'll try out a few boxes of quality stuff to see if that could be the issue. Will try /u/mmiski's idea of testing the trigger pull to see if I might have gotten a bad spring. Yeah it has definitely been high enough for me to take notice of it. Go to 2:55 for the firing-pin part although the entire video is informative for 92 shooters. Like someone else said, don't tap-rack-bang after a LPS, pull that frickin' trigger again FFS! Get that G conversion, you've just discovered why it should be on every 92! As Earnest Langdon said after he discovered the 92G, "Holy Sh**! This is the only thing you guys should be building! I don't understand why'd you build an F!" For exactly this reason I told them to put the 14 lbs spring in mine, and I've already had one or two LPS in the 5k or so that I've put through it. If nothing else were done, the 13 lbs spring will definitely aggravate the LPS problem, but the rest of the trigger job will be replacing things like the hammer and trigger bar which may eliminate the problem. If you get even a single LPS with 20 lbs mainspring, I'm certain something other than spring is wrong. If the ammo doesn't fix it, it's easy enough to leave everything else the same and change back the 20 lbs spring, run a thousand and see what happens. How old is the pistol and what round count? One thing that occurs to me is broken firing pin, it's been known to happen and might have already been broken but the reduced spring aggravated it. Installing steel parts kit may have caused a problem but given that it went back together and the gun fires at all, I'm skeptical that's the problem. I've never heard of that happening in commercial ammo and you don't seem to be loading your own, so I'm skeptical, but easy to rule out. Hard cups are not the only factor, "high primers" (not fully seated in the primer pocket) can also be an issue.

Get some decent commodity ammo until this is sorted out, just to rule it out. All were CCI primers, considered some of the hardest cups available (although S&B are also considered hard). I've put around 25k rounds through a mostly bone stock 92FS with a D spring (equivalent, Wolff 16 lbs) without a single light strike. Has anyone had a similar experience with this, or should I just go back to the stock spring? Thanks in advance for any help or advice!ġ in 100 is way too many, D spring or not, something's wrong. Would this be heavier or lighter than the Beretta D spring? Langdon lists the pull weight for the #13 at 6.3 to 7lbs, but Beretta doesn't have theirs listed. I've been debating buying the Langdon Tactical trigger job in a bag kit with the #13 hammer spring. Could I have messed up something around the firing pin changing those parts that could have caused this? I got the steel parts kit and installed it at the same time as the hammer spring. Made sure I got some extra practice at Tap, Rack, Bang, but also highlighted that I need more practice not accidently hitting the safety during, or to get a G model conversion kit.Īre these ammo brands known to have hard primers? It would be easiest to just not buy those brands again and go from there, but if not I'd prefer not to spend more on training ammo.

This hasn't been too annoying at the range, but also occurred during a course this past weekend.

The primer would be dented and the round would fire if loaded again. I'd estimate 1 out of 100 times it would result in a failure to fire. I figure I've gone through about 1000 rounds of each. Both Sellier & Bellot 124GR and ZQI 123GR. Well I think I have been getting light hammer strikes on two different types of range ammo. It really helped smooth out the double action and has been mostly great. Recently changed out the stock heavy spring on my 92fs for the Beretta D spring. Figured I'd ask the experts here before changing the springs back out or getting a different one.
