Hello,
Recently having issues with my Blade-Tech retention. Seams like the sweet spot is pretty much as loos as it can be without the "Chi-town Screws" falling out lol. Considered Loctite but Id like to have adjustment on the fly. While searching online I noticed that there are some online shops what are selling these thumb retention adjustment screws that do not require a screwdriver to adjust, so with these you can essentially adjust your retention on the fly, maybe have it a little looser before your draw and tighter in between matches? Anyway, to make a long story short. I found what was being charged online for $9.99+shipping, for $2.00 at my local HW store.
For Blade-Tech size needed is 8-32 x 3/4"
