Chapman Mfg Gunsmithing Screwdriver Tools Set 8900: Checking Bit Fit On S&W and Colt Revolvers 

I just got this Chapman gunsmith screwdriver bit set and wanted to see if it was going to be a good fit for some common screws. Pleasantly, it does seem like it’s going to work great for my revolvers from Smith & Wesson and Colt. It conveniently also fits my Rock Island Armory 1911 grip screws.
The kit seems to be high quality and I like the fact it’s made in the USA. Price seemed quite reasonable and the variety of bits is good.
I bought this kit with my own money and am not compensated by any vendors or manufacturers for demonstrating this set. The opinions are my own.
