IMHO - It is about screwdriver fit and hardness, more than 'brand'.

I have a set by 'Chapman' that has an array of 'changeable' tips. The tips are ground to fit the slots of gun screws. The tips fit a handle and handle extension. There is also a lever that fits on the shank of the extension, when more torque is needed.

I also have a screwdriver by Hoppe's which works similar and stores tips in the handle. It is 'magnetized', which I don't like. But, it is convenient for my Range Bag.

I also have a couple sets of those cheap 'Jeweler's Screwdrivers'. They are good for tiny screws.
