, I was thinking of writing about your Q95 issue before Jsega's quoted post beat me to the punch, but I'll put my two cents in anyway before all the pennies are gone.
I'm quite in agreement with his opinion on Shiro liner locks and his suggestion as regards tweaking the lock bar. Just bend it just a little while feeling you've made some difference, then put the knife back together and give it a try. Sometimes it takes a few dis- and re-assembly cycles and bends to get it right, but you should be able to stiffen the detent, making the flipping action a bit crisper and hopefully getting away from being able to shake it out. I've done so a few times with knives both to lighten and strengthen detents. A little fluoro grease on the detent ball helps with both flipping and closing action.
I never had such issues with my Shiro's, though the detent and flip do vary some from knife to knife. Both my F95's, my Neon UL, and 111 all drop shut nicely, but it took getting all the grease out, oiling them lightly, and some break-in over time to get those there. My Hati on washers took quite a few years to
almost get there with a very slight wrist movement to drop closed, while the RDD needs to be shaken closed, though I usually forefinger flick most knives closed anyway. My current and former Tabargans have sliding bar locks and don't count. I had a Quantum Ursus NL that was my only Shiro that dropped shut out-of-box, but I found the knife to be a bit meh and moved it along.
